As shown in fig. 2, the enterprise yield prediction method of this embodiment includes operations S210 to S270.
In operation S210, a share fluctuation mean and a share fluctuation rate of the enterprise whose yield is to be predicted are obtained. The share fluctuation mean is used for describing the status of the company in the industry, if the mean is higher, the company is a monopoly of the industry, and if the mean is lower, the company is a common company in the industry. The share fluctuation rate data represents the industry characteristics, namely, the share low fluctuation rate represents the mature industry, and the share high fluctuation rate represents that the industry is the growth industry. The share fluctuation mean value mu and the share fluctuation rate sigma can be directly specified manually or calculated through historical data, and when a scheme of obtaining parameters from the historical data is adopted, the calculation process is as follows:
in the formula, p i The length of the time window selected for the historical data n is the historical data of the share of the enterprise, and may be selected according to a time situation, such as a month or a year, which is not limited in the embodiments of the present disclosure.
In operation S220, an initial market share of the business is determined, which may be extracted from the business data, for example.
In operation S230, a prediction interval of the market share is calculated using a monte carlo method based on the share fluctuation mean, the share fluctuation rate, and the initial market share.

As shown in fig. 3, the step of calculating the prediction interval of the market share by using the monte carlo method in this embodiment includes:
in operation S310, the step size determining step: determining a step size S of the Monte Carlo simulation, wherein the step size S corresponds to the number of periods for calculating the market share. The specific number of periods may be specified according to an actual situation, for example, 1000 periods or 10000 periods are selected, the larger the number of periods is, the more accurate the estimation result is, but the performance requirement on the computer is higher, and therefore, the actual required accuracy and the existing computing capability may be comprehensively considered for determination, which is not limited in the embodiment of the present disclosure.
In operation S320, a random number generation step: and generating a random number based on the share fluctuation ratio, wherein the random number obeys a normal distribution N (0, sigma), and the sigma is the share fluctuation ratio. N (0, sigma) represents that the generated random numbers obey a normal distribution with a mathematical expectation of 0 and a variance of sigma.
In operation S330, the market share calculating step: calculating the market share of the next period based on the market share of the previous period, the share fluctuation mean, and the random number, wherein the initial market share is the market share of the 1 st period. It should be noted that, each time the market share is calculated, the random number is regenerated to improve the accuracy of the monte carlo prediction.
Exemplary, the formula for calculating market share at stage 2 is:
P 1 ＝P 0 *exp(mu+ep) (2)
the market share for phase x is calculated as:
P x-1 ＝P x-2 *exp(mu+ep) (3)
in the formula, P 1 Is market share of stage 2, P 0 For market share at stage 1, mu is the mean of the share fluctuations, ep is a random number obeying a normal distribution N (0, sigma), and x is 2 ≦ S.
In operation S340, the market share calculating step of the S-th stage: and repeatedly executing the random number generation step and the market share calculation step until the market share of the S-th period is obtained, wherein the market share of the S-th period is used as an intermediate prediction result of the market share.
According to the embodiment of the present disclosure, in the step of repeatedly executing the random number generation step and the market share calculation step until obtaining the market share of the S-th period, when the market share of the F-th period is equal to or less than 0, the market share of the S-th period is made 0; and when the market share of the F-th stage is more than or equal to 1, the market share of the S-th stage is 1, wherein S is more than or equal to F and is more than or equal to 1. In the process of calculating the market share of the S-th stage, if the market share of a certain stage in the middle is less than or equal to 0, the enterprise is broken in production during simulation under the path, so that no market share exists, the market share of the S-th stage is directly judged to be 0, subsequent calculation is not performed, so that the calculation resources are saved, and the calculation speed is increased; similarly, if the market share in a certain period is greater than or equal to 1, it indicates that the enterprise forms monopoly during simulation in the path, so that the market share is directly judged to be 1, and subsequent calculation is not performed.
According to an embodiment of the present disclosure, the step of calculating the prediction interval of the market share by using the monte carlo method further includes: repeatedly executing the random number generation step, the market share calculation step and the market share calculation step of the S-th period M times to obtain M intermediate prediction results of the market shares, wherein M is more than or equal to 2; and intermediate forecasted results of the M market sharesAs a prediction interval for market share. The greater the specific numerical value of M, the more accurate the prediction result is, but the performance requirement on the computer is higher, so that the actually required precision and the existing computing capability may be comprehensively considered for determination, which is not limited in the embodiment of the present disclosure. Illustratively, M may be 10000, i.e. the above-mentioned random number generation step, the above-mentioned market share calculation step and the above-mentioned market share calculation step of the S-th stage are repeatedly executed 10000 times, so as to obtain 10000 market share prediction results P of the S-th stage s 。
Returning to fig. 2, in operation S240, a prediction result of the market share is obtained according to the prediction interval.

For example, in the enterprise market share forecasting scenario, the market share forecasting results include an optimistic forecasting result, a neutral forecasting result and a pessimistic forecasting result, that is, the first forecasting result corresponds to the optimistic forecasting result, the second forecasting result corresponds to the neutral forecasting result, and the third forecasting result corresponds to the pessimistic forecasting result.
According to an embodiment of the present disclosure, the step of obtaining a prediction result of market share according to the prediction interval includes: taking the average value of the first K middle prediction results of the prediction interval to obtain a first prediction result of market share; taking the average value of the middle K middle prediction results of the prediction interval to obtain a second prediction result of the market share; and taking the average value of the last K intermediate prediction results of the prediction interval to obtain a third prediction result of the market share, wherein K is more than or equal to 1/3M and more than or equal to 1. And the prediction interval containing the M intermediate prediction results is converted into a first prediction result, a second prediction result and a third prediction result, so that the subsequent computation amount of the system can be greatly reduced, and the computation speed is improved. The selection of the value K may be determined according to actual conditions, and if the value K is selected to be 50, when the first prediction result is obtained, the intermediate prediction results of the M market shares in the prediction interval need to be sorted from large to small, and an average value of the top 50 intermediate prediction results is taken as the first prediction result. Correspondingly, the second prediction result is the average of the middle 50 middle prediction results, and the third prediction result is the average of the latter 50 middle prediction results. In addition, when the prediction result is obtained, the median of 50 intermediate prediction results may also be taken, and the specific value taking method may be selected according to the actual situation, which is not limited in the embodiment of the present disclosure.
