Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
The first embodiment is as follows:
referring to fig. 1, a method for evolution analysis of a service ecosystem according to a first embodiment of the present invention can be executed by an evolution analysis apparatus of the service ecosystem. In particular, execution by one or more processors in the evolution analysis device to implement steps S1-S4.
And S1, acquiring initial information of the service ecosystem. The service ecosystem comprises a service provider value co-creation unit, a service consumer value co-creation unit and a service platform value co-creation unit, and the initial information comprises the symbiotic action coefficient of each value co-creation unit, the initial scale, the market scale capacity and the natural growth rate.
It is understood that the evolution analysis device may be an electronic device with computing capabilities, such as a portable computer, a desktop computer, a server, a smart phone, or a tablet computer.
It should be noted that the action coefficient, the initial scale, the scale capacity and the natural growth rate may be calculated according to statistical data or estimated values estimated by human, which is not specifically limited in the present invention. It is not limited to how one skilled in the art obtains more accurate values.
The service ecosystem is shown in fig. 2, and specifically, the service ecosystem is an internet-based dynamically-evolving complex ecosystem composed of a large number of services, and is composed of a value co-creation unit, a co-creation mode, and a co-creation environment.
The service ecosystem comprises three types of main bodies, namely a service consumer, a service provider and a service platform. The service provider provides different mass services to meet the requirements of service consumers, the service platform searches and mines the services, uniformly describes and labels the services, and clusters the services with similar functions to form a service function field, so that a service market is formed. The service consumer selects the service suitable for the consumer according to the specific requirement
Value co-creation units refer to a collection of co-creation units having the same or similar functionality. Symbiotic units refer to the basic energy production and units that make up the symbiotic relationship. Each enterprise (i.e. service provider) providing services is a symbiotic unit, the symbiotic units providing the same or similar functional services form a value co-creation unit, and different value co-creation units and third-party service platforms are combined to provide corresponding requirements for consumers.
The symbiotic mode, i.e. symbiotic relationship, refers to the action mode among symbiotic units, which includes four symbiotic modes of competition, parasitism, partial interest symbiosis and mutual benefit reciprocity among service populations. The competition symbiosis mode means that in the environment of value co-creation, different symbiotic units have no symbiotic effect and are mutually exclusive; the parasitic mode means that in the environment of value co-creation, one type of parasitic value co-creation unit is damaged in development, and the other type of parasitic value co-creation unit is benefited in development; the bias mutualism means that in the environment of value co-creation, one type of value co-creation unit develops without damage and without benefit, and the other type of value co-creation unit develops with benefit; mutual profit and mutual benefit represent the symbiotic relationship of two types of value co-creation units in the value co-creation environment, wherein the two types of value co-creation units mutually benefit and mutually win.
The symbiotic environment refers to the sum of all elements except the symbiotic unit, and generally comprises government policy environment, economic environment, cultural environment and the like which can affect the operation of a service ecosystem.
The market environment capacity scale refers to the maximum scale capacity that can be achieved when the scale growth and change of the value co-creation unit are limited by a plurality of factors in the evolution process of the service ecosystem. The balance point refers to the scale of various value co-creation units when the service ecosystem evolves to a certain period to enable the system to reach a stable state. The natural growth rate refers to the growth quantity of the size of the service ecosystem value co-creation unit group in a certain time.
It can be understood that the service ecosystem comprises N types of service provider value co-creation units (for example, in an automobile production and sales service system, a whole automobile product provider, an insurance type service provider, a financial type service provider, a vehicle maintenance type service provider and the like), M types of service consumer value co-creation units and X types of cloud service platform value co-creation units (including a third party service platform value co-creation unit providing only search and a third party service platform value co-creation unit providing search, mining and service combination). The negative symbiotic coefficient represents that the development of the value co-creation unit is damaged, and the positive symbiotic coefficient represents that the development of the value co-creation unit is benefited. In the competitive mode, consider competition between value co-creation units that provide homogeneous functional services.
And S2, constructing a symbiotic evolution model of interaction of each value co-creation unit based on the extended Logistic basic model differential model according to the initial information. The symbiotic evolution model comprises a service provider value co-creation unit symbiotic evolution model, a service consumer value co-creation unit symbiotic evolution model and a service platform value co-creation unit symbiotic evolution model.
It is understood that the service ecosystem is a complex system consisting of a plurality of third party service platforms, a plurality of service providers and a plurality of service consumers, wherein the third party service platforms/service providers/service consumers comprise a plurality of different types of value co-creation units, and each type of value co-creation unit comprises a plurality of variable-scale/number co-creation units.
In a service ecosystem, when the interaction of the value co-creation units is considered, the growth rate of each type of value co-creation unit is influenced by the population scale of the value co-creation unit and the population scale of the value co-creation unit of the other side. Therefore, the symbiotic evolution model of the interaction of the N-type service providers, the M-type service consumers and the X-type third-party service platform value co-creation units can be described through the differential equation of the extended Logistic basic model.
Specifically, the differential model of the extended Logistic basic model is as follows:
N(t0)=N0
wherein N (t) represents the population size of the study subject in the t-th period, a represents the natural growth rate of the study subject population,representing the hindering effect of limited resources on the growth of the research subject's own scale, N*Represents the maximum environmental capacity, N, of the study subject due to resource density constraints0Is the initial population size.

where N is the number of service provider categories, piNatural growth rate, sp, for class i service providersiFor the initial size of the class i service provider,for the largest size of class i service providers,size sp representing the size of various types of service consumers versus the size of the i-th type of service provideriThe effect of growth, M is the number of categories of service consumers,size u for class j service consumerjSize sp for class i service provideriCoefficient of action of ujFor the initial size of class j service consumers,for the largest size of class j service consumers,size sp of class i service provider for other class service providersiThe influence of (c).Scale sp for class s service providersSize sp for class i service provideriCoefficient of action of, spsThe initial size of the class s service provider,maximum size of class s service providers.

S3, calculating and analyzing the progressive stability of the symbiotic evolution model by adopting a Lyapunov first method based on the Jacobian matrix.
Specifically, on the basis of the above embodiment, in an alternative embodiment of the present invention, the step S3 specifically includes the step S31 and the step S32.
And S31, carrying out progressive stability analysis on the symbiotic evolution model, and calculating to obtain an equilibrium point. Wherein the balance point of the symbiotic evolution model comprises E1、E2、E3、E4、E5、E6、E7And E8。

And S32, calculating the stability of each equilibrium point by adopting a Lyapunov first method based on the Jacobian matrix. If all the eigenvalues of the matrix J are negative, the balance point is stable; if at least one of the eigenvalues of matrix J is positive, it is unstable. Wherein, the Jacobian matrix is specifically as follows:
wherein the content of the first and second substances,
the stability at each equilibrium point is: e1Not a stable point, E2Is a balance point between the extinction of two types of service providers and the survival of service consumers, E3And E4Is a balance point where one of the two service providers is alive and the other of the service providers and the service consumer are extinct, E5Is a balance point where both service providers survive and service consumers die, E6And E7Is a balance point where one of the two service providers and the service consumer survive, while the other service provider goes out of service, E8(sp1 *,sp2 *,u*) Is a balance point where two types of service providers and service consumers coexist.
And S4, obtaining an evolution path in the calculation process and the scale of each value co-creation unit when the system reaches a stable state.
The embodiment of the invention fully considers a mesh structure consisting of a plurality of service platforms, service providers and service consumers, explores symbiotic modes and symbiotic conditions of different types of different objects in a service ecosystem by constructing symbiotic evolution models of the plurality of objects based on the extended Logistic model, and can more accurately simulate the service ecosystem so as to accurately obtain required information, such as the evolution process of a value co-creation unit and the scale when the value co-creation unit is stable.
In order to facilitate further understanding of the evolution analysis method of the invention, an example explanation is given below by using a three-class value co-creation unit symbiotic evolution model. For the service ecosystem, when the types of the value co-creation units reach 4, the model calculation amount is huge. To simplify the process without loss of representativeness, the following example simplifies the kinds of value co-creation units involved in the system model as follows. Here, consider that there are only two types of value co-creation units in the service provider: a class A value co-creation unit and a class B value co-creation unit; only one type of value co-creation unit (service consumer with common consumption capability) is considered in the service consumer, and only one value co-creation unit is arranged in the third-party platform.
Specifically, when the types of the service provider value co-creation units are two, the types of the service consumer value co-creation units are one, and the types of the service platform value co-creation units are one, the symbiotic evolution model of each service provider and each service consumer value co-creation unit is as follows:
the symbiotic pattern is shown in table 1:
TABLE 1 value Co-creation Unit Co-occurrence model
Progressive stability analysis was then performed on the model. First, an equalization point is calculated
E1(0,0,0)
E8(sp1 *,sp2 *,u*)
Next, model stability was analyzed using the leiapunov first method using the jacobian matrix. Seven equilibrium points and their stability analysis are shown in table 2:
TABLE 2 seven equilibrium points and stability analysis thereof
For the equalization point E8(sp1*,sp2U), transforming the formula symbiotic evolution model into a formula:
it can be derived that:
when | A |<0 and sp1*>0,sp2*>0,u*>At 0, it is stable. From this, E can be derived8The stable conditions were:
on the basis of the above embodiments, in an optional embodiment of the present invention, the evolution analysis method further includes step S5.
S5, obtaining evolution processes among various value co-creation units corresponding to different co-occurrence coefficients based on Runge-Kutta algorithm, and scales of the value co-creation units when systems corresponding to different market scale capacities reach a stable state.
Specifically, parameters affecting the evolution process and the final scale of each value co-creation unit can be obtained through the step S5. Therefore, the method makes reference to the marketing strategy made by each symbiotic unit and has good practical significance.
More specifically:
a famous automobile brand has a nationwide large market, and an Internet of vehicles service ecosystem comprising a service provider, a service consumer and a third-party service platform is developed on the basis of services such as traditional 4S shop sales, maintenance and the like. In the system, the service providers comprise equivalent value co-creation units of an automobile sales service provider, an automobile owner traffic and life service provider, an automobile insurance service provider and a vehicle maintenance service provider, the service consumers comprise equivalent value co-creation units of common consumers, advanced service consumers and VIP service consumers, and the third-party service platform comprises a value co-creation unit of the Internet of vehicles service platform.
In the symbiotic evolution process of all types of value co-creation units of the service ecosystem, only two types of service providers (each comprising service provider individuals with different scale quantities), one type of service consumers (each comprising service consumer individuals with different scale quantities) and a third-party service platform are considered in the numerical simulation experiment later. Service providers include two types of value co-creation units: insurance type service provider and vehicle maintenance service provider, the service consumer includes a type of value co-creation unit: the common service consumer only has one value co-creation unit of the third-party service platform, namely the Internet of vehicles service platform.
Under different symbiotic modes and symbiotic action coefficients, the symbiotic evolution track and rule of the value co-creation unit can be more intuitively reflected through numerical simulation and visual display, so that a relevant conclusion is obtained. The natural growth rates of the insurance type value co-creation units, the vehicle maintenance type value co-creation units and the common service consumer value co-creation units are respectively assumed as follows: 0.1, 0.15, 0.2; the initial scale was 100. Under a certain resource environment, the three-party development scale is 1000, and the evolution period is 800. By exploring the relationship between symbiotic effect coefficients, the evolution process, the path and the influence factors of the service ecosystem are obtained.
In the following, how the value co-creation units act and co-evolution under different values of the co-creation coefficients, and the influence of factors such as market scale capacity on the scale stability point are discussed.
Firstly, symbiotic mode analysis is carried out, and the influence of factors such as how value co-creation units act and symbiotic evolution under different values of symbiotic action coefficients and the influence of factors such as market scale capacity on scale stability points are discussed
In the present specific case, it is preferred that,representing the symbiotic coefficient influence of common service consumers on the insurance value co-creation unit,shows the influence of the symbiotic coefficient of the vehicle maintenance value co-creation unit on the insurance value co-creation unit,representing the symbiotic coefficient influence of common service consumers on the vehicle maintenance value co-creation unit,shows the influence of the symbiotic coefficient of the insurance value co-creation unit on the vehicle maintenance value co-creation unit,representing the sharing of insurance-like value co-creation units to common service consumersThe generation coefficient is generated by the generator and the generator,and the symbiotic coefficient of the vehicle maintenance type value co-creation unit to the common service consumer is represented.
As shown in fig. 3, when the service ecosystem is in the independent symbiotic mode, the symbiotic coefficient between the value co-creation units is zero, i.e., as shown in FIG. 3, three types of value co-creation units are independently increased from the initial scale to the maximum scale.
As shown in fig. 4, when the service ecosystem is in the normal competitive symbiosis mode and the symbiotic coefficient range is (-1, 0), the evolution paths of the value co-creation units are basically consistent, and the final scale stable points of the three value co-creation units are consistent. In the competitive symbiosis mode, the larger the absolute value of the symbiotic action coefficient is, the smaller the final scale stable equilibrium point is, the slower the evolution speed is, and the longer the final scale stable evolution time is.
As shown in fig. 5, when the service ecosystem is in the malignant competition symbiotic mode, the symbiotic coefficient is in the (-1- ∞) interval, which is the evolution of the malignant competition symbiotic mode. In the value co-creation units, at least one value co-creation unit evolves to gradually increase and finally reaches the trend of a stable state, and the final stable value is the maximum scale; at least one value co-creation unit is greatly inhibited from evolving, and tends to grow and weaken, and finally dies up.
As shown in fig. 6, when the service ecosystem is in the parasitic symbiotic mode, the symbiotic coefficients between any two kinds of the value co-creation units are opposite numbers, the parasitic value co-creation unit resources are consumed, the final stable scale is smaller than the maximum scale, the parasitic value co-creation unit benefits from the parasitic value co-creation unit, and the final stable scale is higher than the maximum scale under independent symbiosis. In the mode, more resources are needed among the value co-creation units, and the value sharing further promotes the symbiotic evolution, so that the system benefit maximization is realized. In the parasitic mode, the larger the absolute value of the co-occurrence coefficient, the larger the final stable value of the parasitic value co-creation unit.
As shown in fig. 7, when the service ecosystem is in the partial interest symbiosis mode, the symbiosis coefficients between any two types of value co-creation units are one zero and the other is greater than zero. Under the partial interest symbiosis mode, along with the increase of the symbiotic action coefficient, the evolution paths of the value co-creation units are basically consistent (gradually increased firstly, and are kept stable after reaching the maximum value), but the respective reached stable values are different; the larger the symbiotic effect coefficient is, the faster the symbiotic evolution speed is, and the larger the scale value to reach a stable state is.
As shown in fig. 8, when the service ecosystem is in the mutual-benefit mode, the mutual-benefit coefficient between any two populations is positive, and the final stable state of the population is larger than the maximum independent development scale. The symbiotic coefficient of the interaction of the three value co-creation units is larger than zero, the scale growth of any one part benefits from the other two main bodies, the stable value of the main body scale exceeds the maximum scale value of independent development, and the final stable point is E8(sp1 *,sp2 *,u*). Under the mutual-benefit mutual-generation symbiosis mode, the larger the symbiosis coefficient is, the larger the final scale stable equilibrium point is. According to simulation results in different symbiotic modes, symbiotic evolution of the service ecosystem value co-creation units is related to the symbiotic action coefficient. Under the mutual-benefit and mutual-benefit symbiosis mode, the final stable scale of the co-creation unit is the largest, and the co-creation unit is the best direction for symbiotic evolution of the service ecosystem.
And then carrying out simulation analysis on the relevant factors. Based on a reciprocal and mutual benefit symbiotic mode, the influence of the natural growth rate of the value co-creation unit, the initial scale of the value co-creation unit and the market capacity scale of the value co-creation unit on symbiotic evolution is explored.
As shown in fig. 9, in the mutualistic symbiotic mode, when the natural growth rate increases, the final stable scale does not change. This can result in: the symbiotic evolution stable point of the value co-creation unit is irrelevant to the natural growth rate of the value co-creation unit.
As shown in fig. 10, in the mutualistic symbiotic mode, when the initial scale is increased, the final stable scale is not changed, and it can be seen from the figure that the larger the initial scale is, the faster the evolution rate is. This can result in: the symbiotic evolution stable point of the value co-creation unit is independent of the initial scale of the value co-creation unit, and the larger the initial scale is, the faster the symbiotic evolution speed is.
As shown in fig. 11, the symbiotic evolution stability point of the value co-creation units is related to the market-scale capacity thereof, and the larger the market-scale capacity of each type of value co-creation unit is, the larger the stability-scale value is.
