[0061] As noted in the Description of Related Art, the prior-art credit risk assessing modes on the one hand cannot acquire complete client information, operational information of the client in particular, whereby bad loan rate is rendered high, on the other hand, collection of client information via prior-art information obtaining mode is problematic in terms of long time duration and high cost of manpower, etc.
[0062] In order to overcome the aforementioned problems, in the embodiments of the present invention is creatively proposed a method of assessing user credit risk, the method utilizes user information data provided by a core enterprise in the supply chain (namely a first target platform) to extract information capable of differentiating clients credits, sets admission conditions and credit lines, and performs overall judgment on clients credits in combination with data provided by a third-party servicing company (such as a credit investigation company), thereby carries out credit loans to downstream clients of the core enterprise that satisfy the conditions, whereby credit risk assessing efficiency is enhanced, and bad loan rate of credit is lowered at the same time.
[0063] Fig. 1 is a flowchart illustrating the method of assessing user credit risk according to an exemplary embodiment. With reference to Fig. 1, the method comprises the following steps.

Date recue / Date received 2021-12-09
[0064] Si - obtaining a first user data of a target user on a first target platform and a second user data of the target user on a second target platform.
[0065] Specifically, the core enterprise of the supply chain usually possesses large data of downstream clients (such as small and micro enterprises), these data are mainly the information of the downstream clients picking up (purchasing) goods from the core enterprise, including, but not limited to, times and quota of picking-up per month, seasonal fluctuation rates of goods, categories of goods, and cooperation durations with the core enterprise, and so on. As a kernel link in the supply chain, the core enterprise sometimes collects some basic information of the clients, including the locations where clients businesses concentrate, and the circumstances of the downstream clients, etc. Many core enterprises further have their own reward and punishment mechanisms with respect to clients delivery, rewarding clients to pick up goods according to targets or even over the targets, these information and the information of downstream clients having been previously overdue in other financial institutions serve as very good indicators with which to judge the credits of the downstream clients.
[0066] In the embodiments of the present invention, the target user includes, but is not limited to, a small and micro enterprise, the first target platform includes, but is not limited to, a core enterprise in the supply chain, the first user data includes user data possessed by the core enterprise, the second target platform includes, but is not limited to, a credit investigation company, and the second user data includes credit investigation data of the user.
[0067] S2 - employing a preset algorithm to analyze the first user data, and obtaining a target variable to which the target user corresponds, wherein the target variable includes a variable describing credit risk of the target user.
[0068] Specifically, after the first user data provided by the first target platform has been obtained, it is required to base on the first user data to analyze the circumstances of the target Date recue / Date received 2021-12-09 user. During specific implementation, a preset algorithm can be employed to analyze the first user data, and the analyzed contents include, but are not limited to, distribution of various features of the client, distribution of circumstances of the client whose credits have been overdue in other banks, distribution of rewards and punishments for delivery, and distribution of delivery amounts of the client, etc. A risk indicator (namely target variable) is reasonably set in conjunction with the distribution circumstances of data and overdue features.
[0069] S3 - determining an initial admission condition of credit according to the target variable and a preset threshold.
[0070] Specifically, after the target variable has been determined, a corresponding initial admission condition is set in conjunction with the target variable and a preset threshold. Besides the target variable as chosen, consideration can be also given to some apparently financially meaningful conditions. Setup of the initial admission condition here can be combined with the analyzing result in the previous step.
[0071] The initial admission condition includes, but is not limited to, the following.
[0072] no appearance on the blacklist of the core enterprise of the supply chain;
[0073] exclusion of clients with inferior or severe overdue circumstance (over 7 days) on the credit list of the core enterprise of the supply chain;
[0074] exclusion of provinces or cities to which the business is temporarily not extended (due to reasons of small business quantity, undeveloped economy or inferior credit environment, etc.);
[0075] exclusion of clients whose yearly picking-ups of goods are less than three months (low picking-ups indicate unstable business);
[0076] exclusion of clients who pick up goods in just one month or less than one month in the recent three months;
[0077] exclusion of clients whose amount of goods picked up is less than 500,000 yuan RMB
(unduly low picking-up quota cannot get high credit line, being low in risk but also low in efficiency);
Date recue / Date received 2021-12-09
(unduly low picking-up quota cannot get high credit line, being low in risk but also low in efficiency);
Date recue / Date received 2021-12-09
[0078] exclusion of clients whose order completion rate is lower than 30%;
[0079] exclusion of clients whose amount of goods picked up is reduced over 50% on a year-on-year or month-on-month basis within one year; and
[0080] exclusion of clients who opened accounts at the core enterprise less than one year.
[0081] S4 - readjusting the initial admission condition according to the second user data, and obtaining a target admission condition.
[0082] Specifically, the third-party credit investigation company and the Central Bank can also provide a lot of information relevant to a downstream client (a target user), such as business information of the client, judicially involved information, social loan information, etc. These information can provide fuller knowledge of each downstream client. The information provided by the core enterprise (first user data) and the credit investigation information (second user information) are combined to readjust the initial admission condition obtained in the previous step to obtain target admission data.
[0083] S5 - determining a credit line of each target user that conforms to the target admission condition according to the first user data and the second user data.
[0084] Specifically, by analyzing the first user data obtained from the first target platform in combination with experiences acquired from other projects can be sorted out the upper limit of creditable line of each target user. On the other hand, from information provided by the Central Bank or a third-party credit investigation company (namely the second user data of the second target platform) can be analyzed out the credit circumstances of each target user in other banks, including creditable line, already used line, overdue or collection information, etc. The actual creditable line of each target user can be obtained by combining the information of these two aspects.
[0085] As a preferred mode of execution in the embodiments of the present invention, the step Date recue / Date received 2021-12-09 of employing a preset algorithm to analyze the first user data, and obtaining a target variable to which the target user corresponds includes:
[0086] constructing a risk variable according to the first user data and a preset rule, wherein the risk variable is used to describe credit risk of the target user; and
[0087] employing a preset algorithm to analyze the risk variable according to preset dimensions, and screening the target variable out of the risk variable according to an analyzing result and a preset screening threshold.
[0088] Specifically, constructing a risk variable is to construct those potential variables that are capable of reflecting credit levels of the user. The risk variable constructed according to the first user data and a preset rule includes, but is not limited to, the number of months within a year in which orders are completed, goods picking-up quota in one year, credit balance, the number of months in which goods are picked up in the last year, the number of months in which goods are picked up in the last six months, the number of months in which goods are picked up in the last three months, goods picking-up quota in the last year, goods picking-up quota in the last six months, goods picking-up quota in the last three months, year-on-year growth rate of goods picked up in the last year, month-on-month growth rate of goods picked up in the last year, year-on-year growth rate of goods picked up in the last six months, month-on-month growth rate of goods picked up in the last six months, year-on-year growth rate of goods picked up in the last three months, month-on-month growth rate of goods picked up in the last three months, the region (province, city) where the client resides, the time when the client opened account, the amount of orders completed in the last year, etc. Economically speaking, these variables are related in certain extent to the non-performance of the client.
[0089] When the preset algorithm is employed to analyze the risk variable, dimension information to be analyzed can be set in advance according to actual requirements, the analyzing result as obtained is compared with a preset screening threshold, and a target variable that conforms to the requirements is screened out of the risk variable.

[0090] As a preferred mode of execution in the embodiments of the present invention, the preset algorithm includes a first preset algorithm and a second preset algorithm, the screening threshold includes a first screening threshold and a second screening threshold, and the step of employing a preset algorithm to analyze the risk variable according to preset dimensions, and screening the target variable out of the risk variable according to an analyzing result and a preset screening threshold includes:
[0091] employing the first preset algorithm to analyze the risk variable according to preset dimensions, and obtaining a first analyzing result;
[0092] screening out a plurality of risk variables according to the first analyzing result and the preset first screening threshold;
[0093] employing the second preset algorithm to analyze the plural risk variables, and obtaining a second analyzing result; and
[0094] screening the target variable out of the plural risk variables according to the second analyzing result and the preset second screening threshold.
[0095] Specifically, in the embodiments of the present invention, employing the preset algorithm to analyze the risk variable according to preset dimensions includes analyzing a single risk variable and analyzing a plurality of risk variables, and employing the first preset algorithm to analyze the risk variable according to preset dimensions includes, but is not limited to, the following:
[0096] analyzing the number of months within one year in which the target user completes orders, the distribution of months, and the relation between goods picking-up quota in a total year and non-performance of the client ¨ usually speaking, the more number of months within one year in which orders are completed, the better;
[0097] analyzing credit balance distribution, overdue or non-performing balance distribution of the target user, and the relation between credit balance and overdue or non-performance on the basis of the first user data provided by the first target platform ¨ severely overdue (such as over Date recue / Date received 2021-12-09 30 days) and non-performing clients should be avoided;
[0098] analyzing the number of months in the last year in which goods are picked up, the number of months in the last six months in which goods are picked up, and the number of months in the last three months in which goods are picked up by each target user, and analyzing the relation between these data and change in goods picking-up quota of the client and possible overdue circumstances ¨ the more number of months in which goods are picked up, the better is the downstream business;
[0099] analyzing the relation between non-performance and the year-on-year and month-on-month growth rates of goods picked up in the last year, the year-on-year and month-on-month growth rates of goods picked up in the last six months, and the year-on-year and month-on-month growth rates of goods picked up in the last three months, and analyzing the relation between these growth rates and change in goods picking-up quota of the client in a total year and possible overdue circumstances ¨ usually speaking, a well operating company achieves stable increase in both the year-on-year and month-on-month growth rates of goods picking-up quota, and there is better not much fluctuation, as a less fluctuating and stably increasing client is the first choice for credits;
[0100] analyzing the relation between the region where the target user resides and the non-performance of the client ¨ different regions have different economic development levels, credit environments and credit cultures, clients from regions with higher economic development levels and better credit cultures are the first choice, and region selection should take potential business volumes, credit environments and economic development levels of regions into overall consideration;
[0101] analyzing the relation between the time when the target user opened account and the non-performance of the client ¨ in the case the account was opened too short, there is no sufficient historical data accumulation of the client, and there is also no way to analyze Date recue / Date received 2021-12-09 corresponding data and behaviors; generally speaking, the client's account should have been opened at least one year before sufficient goods picking-up history of the client can be accumulated for analysis;
[0102] analyzing the relation between the non-performance of the client and the goods picking-up quota in the last year, the goods picking-up quota in the last sixth months, and the goods picking-up quota in the last three months of the target user ¨ the goods picking-up quota is the data upon which the credit line mainly depends, the higher and more stable the goods picking-up quota of the client is, the better it will be, and the change in the goods picking-up quota of the client is closely related to the change in the operational circumstances of this client, so it is required to clearly analyze the potential tendency of the goods picking-up quota; and
[0103] analyzing the relation between the order completion rate of the target user in the core enterprise and the non-performance of the client ¨ the levels whereby orders are completed predict to some extent the levels of operations of the downstream enterprises.
[0104] The relations analyzed above can be reflected through certain statistics, including such statistic indices as AUC and KS. A first screening threshold is provided to the statistic index of each risk variable, and risk variables exceeding the certain first screening threshold are preliminarily selected to pass. After passing the first round of screening, plural risk variables possessing the capability to apparently differentiating client risks are screened out to serve as basis for the next round of analyzing a plurality of risk variables.
[0105] Analyzing a plurality of risk variables mainly aims to find out a collection of variables most capable of differentiating client credit levels. Likewise, a second screening threshold can be preset while the plural risk variables are being analyzed, the analyzing result is compared with the second screening threshold, and the optimal variable is screened out of the plural risk variables to serve as the target variable.

Date recue / Date received 2021-12-09
[0106] As a preferred mode of execution in the embodiments of the present invention, the second preset algorithm includes a regression algorithm, and the step of employing the second preset algorithm to analyze the plural risk variables, and obtaining a second analyzing result includes:
[0107] performing a discretization process on the plural risk variables, and obtaining fragments to which the plural risk variables correspond; and
[0108] employing the regression algorithm to perform regression analysis on the fragments, and obtaining the second analyzing result.
[0109] Specifically, many methods can be employed to analyze the plural risk variables, such as methods of linear regression, logistic regression and decision tree. Taking logistic regression for example, the logistic regression can employ the modes of forward regression, backward regression, and simultaneous forward regression and backward regression. What a mode is specifically employed can be decided by comparing plural results to see which mode is the best.
[0110] Before the plural risk variables are analyzed, the variables should be converted, and such conversion includes, but is not limited to, the WOE mode, namely to subject the variables to discretization to be partitioned into plural fragments, and to calculate the ODDS of each fragment, namely a ratio between quality clients and inferior clients, which ratio is used to enter regression analysis of the next step. Judging which variables are the best can be measured by indicators with regression effects, and the indicators with regression effects include such statistics as AUC value, KS value and relevancy, etc., to which no definition is made in the embodiments of the present invention, as it is possible for users to base on actual requirements to select one or more therefrom. Taking the AUC value for example, a collection of variables with the best AUC value is selected through the foregoing steps to serve as the target variable.
[0111] As a preferred mode of execution in the embodiments of the present invention, the coefficient of the regression result of the aforementioned plural risk variables can be further taken as a reference to setting the initial admission condition. When the product of the coefficient Date recue / Date received 2021-12-09 with the ODDS of a corresponding variable is apparently lower than the average value, for instance, lower than twice as much as the average value minus a standard difference, then the value of a variable to which the value twice as much as the average value minus a standard difference corresponds can be set as a threshold. Each variable is performed with similar analysis before the corresponding threshold of each variable can be obtained.
[0112] As a preferred mode of execution in the embodiments of the present invention, the step of employing a preset algorithm to analyze the first user data, and obtaining a target variable to which the target user corresponds includes:
[0113] classifying the target user according to a preset classifying rule, and obtaining a classified type to which each target user corresponds;
[0114] determining any target user that satisfies a preset analyzing condition according to the classified type; and
[0115] employing a preset algorithm to analyze the first user data to which the target user that satisfies the analyzing condition corresponds, and obtaining a corresponding target variable.
[0116] Specifically, in order to enhance risk assessing precision, in the embodiments of the present invention, when the preset algorithm is employed to analyze the first user data, the first user data of a non-performing client (also referred to as "inferior client") can be selected for analysis, so as to analyze out features of the non-performing client to serve as reference to subsequent setting of the admission condition. Accordingly, it is possible to firstly ascertain definitions of the non-performing clients; during specific implementation, clients whose loans were once overdue, clients appearing on the blacklist of the core enterprise, and clients having no amount paid to picked up goods in six months are defined as inferior clients or non-performing clients, while clients clear of the above circumstances are defined as quality clients.
[0117] Target users are classified according to the above definitions, the classified type to which each target user corresponds is judged as to whether the target user is a quality client or an inferior client, those target users that pertain to non-performing clients are screened out, and the Date recue / Date received 2021-12-09 first user data to which these target users correspond is analyzed to obtain corresponding target variables.
[0118] As a preferred mode of execution in the embodiments of the present invention, the step of determining a credit line of each target user that conforms to the target admission condition according to the first user data and the second user data includes:
[0119] determining a first line of each target user that conforms to the target admission condition and a coefficient to which the first line corresponds according to the first user data and a preset line table;
[0120] determining a second line of each target user that conforms to the target admission condition according to the second user data; and
[0121] calculating to obtain the credit line of each target user that conforms to the target admission condition according to the first line, the coefficient, and the second line.
[0122] Specifically, in the embodiments of the present invention, it is possible to base on actual requirements to set the formula for calculating the credit line of a target user, as a preferred example, the calculation formula can be as shown below:
credit line = max (basic line * coefficient ¨ Central Bank credit investigation used line, 0)
credit line = max (basic line * coefficient ¨ Central Bank credit investigation used line, 0)
[0123] What should be determined in the formula are the two parameters of basic line and coefficient, the Central Bank credit investigation used line indicates credit extension obtained in the name of an enterprise, calculated is only the used credit line already extracted, and this can be extracted from a credit investigation report of the Central Bank. The basic line is the first line, and the Central Bank credit investigation used line is the second line. The principle of setting credit lines of the target user is that the profitability of the client is capable of covering the existent credit line and the newly added credit line.
[0124] The basic line mainly takes into consideration the safety of the line as provided, after the user has passed the target admission condition, the basic line is mainly related to the Date recue / Date received 2021-12-09 repayment capability of the user, while the repayment capability is mainly related to the income of the user. By way of example, the sales amount of money (goods picking-up amount of money) of the user can be used as a benchmark for consideration, and the basic line is realized by multiplying the benchmark with a certain proportion. A reasonable base is 20%
to 40% of the goods picking-up amount of money, the consideration here is that a certain proportion of the goods picking-up amount of money should be in loan, and the loan limit is risky when this certain proportion is exceeded; after a certain period of time with credit history in the future, this proportion may be increased or decreased according to non-performing circumstances of the client. This proportion is also closely related to the core enterprise (first target platform), as the stronger the core enterprise is, the higher can be the proportion.
to 40% of the goods picking-up amount of money, the consideration here is that a certain proportion of the goods picking-up amount of money should be in loan, and the loan limit is risky when this certain proportion is exceeded; after a certain period of time with credit history in the future, this proportion may be increased or decreased according to non-performing circumstances of the client. This proportion is also closely related to the core enterprise (first target platform), as the stronger the core enterprise is, the higher can be the proportion.
[0125] As an example, calculation of the basic line can be as shown in the following Table.
Table 1 Table of Correspondence between Sales Amount of Money and Basic Line Sales Amount of Money of the Target Corresponding Basic Line User in the Last 12 Months 0-500,000 yuan RMB 0 yuan RMB
500,000¨one million yuan RMB 200,000 yuan RMB
one million-2.5 million yuan RMB 400,000 yuan RMB
2.5 million-5 million yuan RMB 1 million yuan RMB
million-7.5 million yuan RMB 2 million yuan RMB
7 million-10 million yuan RMB 3 million yuan RMB
over 10 million yuan RMB credit to be manually examined and approved

one million-2.5 million yuan RMB 400,000 yuan RMB

[0126] The corresponding coefficient should be further determined after the basic line has been well determined. The coefficient is a parameter with which to adequately readjust the basic line based on other information or newly appearing information after the basic line has been given.
The higher the coefficient is, the better will be the credit of the enterprise, otherwise, a lower Date recue / Date received 2021-12-09 coefficient indicates that the enterprise falls short of perfect credit or leaves something to be desired of the credit.
The higher the coefficient is, the better will be the credit of the enterprise, otherwise, a lower Date recue / Date received 2021-12-09 coefficient indicates that the enterprise falls short of perfect credit or leaves something to be desired of the credit.
[0127] The coefficient is preliminarily determined as follows:
Table 2 Table of Correspondence between Order Completion Circumstance and Coefficient Order Completion Circumstance in the Corresponding Coefficient Last 12 Months 80%+ order overfulfilled 1 65%-80% order overfulfilled 0.9 50%-65% order overfulfilled 0.8 35%-50% order overfulfilled 0.7 0-35% order overfulfilled over upper limit 0.7, to be decided by credit examining personnel
Table 2 Table of Correspondence between Order Completion Circumstance and Coefficient Order Completion Circumstance in the Corresponding Coefficient Last 12 Months 80%+ order overfulfilled 1 65%-80% order overfulfilled 0.9 50%-65% order overfulfilled 0.8 35%-50% order overfulfilled 0.7 0-35% order overfulfilled over upper limit 0.7, to be decided by credit examining personnel
[0128] After the coefficient has been determined, it is then considered to readjust the coefficient.
Readjustment of the coefficient mainly reflects the information of the user relevant to recent change in credit risk, and the information includes possible negative early warning signals, abrupt decrease in the sales (goods picking-up) amount of money, and overdue circumstances of currently existing credits, etc. And readjustment of the coefficient aims to adequately lower the credit level of the client, control the credit line of the client, and even reject loan to the client when potential risk is encountered.

[0129] The main conditions relevant to readjustment of the coefficient include, but are not limited to, the following:
[0130] lowering the coefficient for one grade if there is an early warning signal against the target user;
