Research on Supernetwork Equilibrium about Deep Convergence of Enterprise Alliance for Breakthrough Innovation

+e realization of breakthrough innovation with high risk and uncertainty has always been the focus of the theory and practice of technological innovation. Based on the supernetwork theory, this paper constructs a supernetwork equilibriummodel about deep convergence of enterprise alliance for breakthrough innovation and uses numerical simulation tools to find out the equilibrium conditions for deep convergence of enterprise alliance in different stages of breakthrough innovation. It is not only conducive to understand the process of enterprise alliance’s deep convergence in “Creativity-Research-Production-Sales” but also helpful to understand the roles that deep convergence in enterprise alliance can play in achieving breakthrough innovation. It not only expands the existing research on breakthrough innovation but also provides a scientific reference for the deep convergence of enterprise alliance in practice.


The Introduction
Breakthrough innovation is considered a kind of discontinuous innovation that breaks away from the original technological trajectory and significantly reduces the product cost or improves the product performance in a revolutionary way, which will have a huge impact on the market and industry [1]. e formation of breakthrough innovation has great contingency and uncertainty, and it is difficult for enterprises to realize the process of breakthrough innovation from technology research, technology productization to marketization by themselves. With the accelerated development of science and technology, the innovation paradigm of enterprises has changed from "closed competition" to "open collaboration," and the boundary about organizations has been gradually diluted. Organizational cooperation has become the key content in the field of breakthrough innovation. Enterprises need to acquire a large amount of internal and external resources and establish enterprise alliance partnerships, so as to obtain more development opportunities through deep convergence, collaboration, and cross-border search. At present, more and more enterprises begin to explore the convergence mode that take themselves as the leading factors and combine the multiple innovation subjects. e enterprise alliance of "multialliance and multiproject" has been paid attention to in practice and research as the most representative convergence mode. e diversity of alliance combinations is conducive to the generation of breakthrough innovation [2]. Enterprises build alliance network relations by selecting members with different industry attributes or crossing different knowledge boundaries, which can help to enhance the convergence among organizations and facilitate the transfer and absorption of enterprises' knowledge in the stage of technology research, and it is conducive to share the material supply, marketing, and sales channels in the stage of commercialization. It is also helpful to improve the innovation ability of alliance enterprises and accelerate the pace of enterprise innovation [3]. e diversity of technology, information, production capacity, and users within the alliance enterprise lays a foundation for the enterprise to acquire abundant heterogeneous innovation resources, which is conducive to the formation of breakthrough innovation and to reduce the risks and uncertainties in the process of breakthrough innovation, so as to avoid the "locking effect" of the enterprise and realize risk sharing [4]. erefore, enterprise innovation strategic alliances can significantly promote enterprise breakthrough innovation [5], and the establishment of a benign alliance network relationship has important practical significance for the breakthrough innovation of enterprises. e deep convergence of enterprise alliance for the breakthrough innovation is not only the convergence across the enterprises but also a process in which innovation participants participate in the generation of new technological ideas, the formation, and marketization of new products. e collaborative innovation model among alliance enterprises lays an important foundation for leapfrog development and promotes the occurrence of deep convergence. Some scholars have realized that knowledge, technology, products, and market are closely attached to the collaborative cooperation among enterprises. Due to the high risk of breakthrough innovation activities and the uncertainty of the result of deep convergence among alliance enterprises, it will bring delayed or even loss-making economic returns to enterprise alliances. erefore, alliance enterprises should establish a comprehensive system of deep convergence, and the supernetwork theory provides ideas for this study to explore the process of deep convergence within the enterprise alliance based on the knowledge characteristics, technical characteristics, product characteristics, and market characteristics. is paper combines the collaborative cooperation of alliance enterprises with the deep convergence of "Creativity-Research-Production-Sales" by drawing on the method of supernetwork and finds out the supernetwork equilibrium conditions about the deep convergence of the enterprise alliance for breakthrough innovation which is of great significance for enterprises to achieve breakthrough innovation, establish the alliance partnerships, and explore the deep convergence about each stage of breakthrough innovation.
is study mainly includes the following four steps: the first step is to deeply study the stages of breakthrough technological innovation and deep convergence and then use the supernetwork theory to connect them into the deep convergence supernetwork of enterprise alliance for breakthrough innovation. e second step is to construct the deep convergence supernetwork, which is composed of knowledge convergence subnetwork, technology convergence subnetwork, production convergence subnetwork, and market convergence subnetwork. e third step is to construct and analyze the supernetwork equilibrium model and propose the mathematical model. Finally, in the fourth step, the problems are described and the parameters are set, the mathematical model of the integrated structure is built, and then the simulation results are analyzed. We put forward the optimization and management strategies of the supernetwork equilibrium model about the deep convergence of enterprise alliance for breakthrough innovation, as shown in Figure 1.

e Stage of Breakthrough Innovation Formation.
e formation of breakthrough innovation with high uncertainty and contingency has caused great difficulties to the research of breakthrough innovation; however, the stage characteristics of breakthrough innovation are relatively clear. We can grasp the results of breakthrough innovation starting from different stages of breakthrough innovation. e formation of breakthrough innovation needs to be based on the analysis of the characteristics in each stage. e origin of breakthrough innovation can be traced back [6], and the process or stage of breakthrough innovation can be dynamically tracked. Existing studies have many ways to classify the stage of breakthrough innovation but generally include the creativity stage, technology stage, products stage, and market stage [7]. e creativity stage is fuzzy, unconventional, dynamic, and uncertain, and the front-end planning is unpredictable, with few prior strategies [8]. e generation of fuzzy front-end creativity needs the convergence and creation of diversified creative knowledge [9]. e technology stage is a process from the generation of ideas to the emergence of new technologies. Breakthrough technology is a new technology that has separated itself from the existing technological trajectory, showing the characteristics of diversity, frontier, complexity, pioneering, breakthrough, and convergence [10]. erefore, higher requirements are imposed on enterprises, forcing enterprises to establish cooperation with external organizations and obtain information, knowledge, capital, and other resources through higher network structure, relationship, and cognitive embeddedness of alliance enterprise [11]. e production stage is the result of the joint action of each enterprise. e enterprise alliance cooperates with each other to provide supporting measures such as equipment and services. In the market stage, the restructuring of the market pattern is the main feature of breakthrough innovation.

Deep
Convergence. At present, we focus more on technology convergence; the convergence is not just a single, isolated phenomenon at the technological level. In the process of the emergence and development of convergence, not only do the relevant basic and applied science provide important support for convergence but also the industrial convergence is closely related. In addition, it is also affected by the social economy, legal rules, and users and other influencing factors. erefore, we can understand and master the operation mechanism and dynamic characteristics of deep convergence including technology convergence more accurately and comprehensively by adopting the system point of view. Acklin divided the whole convergence process into four time series: knowledge convergence, technology convergence, application convergence, and industry convergence through observation and practical case analysis. Curran et al. proposed a similar framework, but the difference is that he replaced application convergence with market convergence and proposed the convergence evolution framework of "knowledge convergencetechnology convergence-market convergence-industry convergence" [12].
In this paper, the deep convergence of enterprise alliance for breakthrough innovation starts from cross-referencing among various scientific fields and gradually goes into the multidisciplinary knowledge convergence. As the distance about basic disciplines is gradually shortened and the technology is constantly developing, technology convergence occurs, and it further promotes the emergence of new products, leads to the emergence of market convergence, and finally completes the industrial convergence. It is the process of breakthrough technology from formation to marketization and finally subverting the market and industry, as shown in Figure 2.

Supernetwork
eory. Supernetwork theory is established on the basis of complex network research, which is used to describe the interaction and influence in different networks. Supernetwork is a method to study multidimensional equilibrium and optimization of various important attributes. It goes beyond the real network and is at the forefront of graph theory and network science. Supernetwork has the characteristics of multilayer, multidimension, multiattribute, multicriteria, convergence, and congestion. Supernetwork is composed of the subnetwork with related logical relationships, and each subnetwork is a relatively independent operation of the subsystems, which interact with each other through the connection and mutual influence between the nodes. e reliability of the whole network depends on the interaction and status of each subnetwork.
is study uses the supernetwork theory to connect the stages of breakthrough technological innovation and the stages of deep convergence into the deep convergence supernetwork of enterprise alliance for breakthrough innovation. Breakthrough innovation cannot be separated from the role of the network [13]. e success of breakthrough innovation requires the contributions and convergence of knowledge, information, technology, products, and markets, and the formation of breakthrough innovation comes from the joint efforts of many participants in the   e deep convergence supernetwork of breakthrough innovation is made up of many enterprises as nodes with different roles. e conflict about the demand for external resources and the nonsharing of internal resources among enterprises leads to the formation of a breakthrough innovation network which provides enterprises with knowledge, technology, equipment, market, and other resources, so as to ensure the innovation performance of the enterprise. So, this paper argues that the composition of deep convergence supernetwork of breakthrough innovation should be viewed from both horizontal and vertical aspects: first, from the perspective of the enterprise, deep convergence supernetwork of breakthrough innovation is composed of the interaction mode among the alliance enterprises. In the network, enterprises can make use of various interorganizational relations to obtain resources [14], which provides a guarantee for the realization of breakthrough innovation. Second, from the perspective of the breakthrough innovation stages and deep convergence stages, the formation of deep convergence supernetwork of breakthrough innovation goes through the knowledge convergence stage, technology convergence stage, production convergence stage, and market convergence stage. At each stage, different participants including alliance enterprises cooperate with each other and make efforts to construct the supernetwork and ensure the formation of breakthrough innovation, as shown in Table 1.

Construction of Deep Convergence Supernetwork of Enterprise Alliance for Breakthrough Innovation
Breakthrough innovation is the process of evolving from breakthrough technology to product and finally entering the market. e value of breakthrough innovation is realized only through a complete experience of "Creativity-Research-Production-Sales."

Knowledge Convergence Subnetwork (Creativity Stage).
Breakthrough innovations often require a large investment of heterogeneous knowledge that cannot all be acquired from the internal organization. According to resource-based theory and social network theory, acquisition of knowledge from outside can not only relieve the resources constraint of enterprises but also obtain complementary resources, so as to avoid the rigid problems of breakthrough innovation ability caused by the single source of knowledge [15]. According to the theories of network partnership and interorganizational learning, enterprise alliance can significantly promote the acquisition, interpretation, utilization, and creation of interorganizational tacit knowledge and thus accelerate the breakthrough innovation of enterprises [16].
According to the theory of knowledge-based, enterprises need to invest a lot of new knowledge to implement breakthrough innovation, but how to acquire new knowledge from external organizations effectively is the key to ensure the realization of breakthrough innovation [17]. Enterprise alliance is conducive to enhancing the degree of interaction between enterprises, and the exchange and communication among enterprises can not only close the distance of enterprises but also help to improve the level of knowledge convergence among enterprises. e network relationship of enterprise alliance builds a good communication and exchange platform for enterprises. e alliance enterprises can acquire a large amount of external knowledge through this platform and generate new knowledge through absorption, digestion, utilization, and knowledge convergence, which is conducive to the formation of breakthrough innovation.

Technology Convergence Subnetwork (Technology R&D Stage).
In the context of the current technology convergence, the technology structure level, innovation mode, and innovation degree have changed greatly. Driven by breakthrough innovation, previously unrelated technologies are beginning to merge with each other [18]. e cross-border innovation of technology can break the shackles of the previous knowledge structure on the technological trajectory [19]. In this mode of innovation, many previously unrelated domains or technologies that span different knowledge structures are combined to produce new functions or applications, thus enabling technological innovation to complete the leapfrog of the technological trajectory. Breakthrough innovation results from the technological trajectory transition [20], so the convergence of different technologies promotes the evolution of breakthrough innovation. Enterprise is the main driving force of technological development, which obtains the technologies through technology acquisition, licensing, authorization, or equity alliances and utilizes the technologies to achieve technology convergence. e enterprise alliance makes the technology convergence barrier disappear. Breakthrough innovation is not limited to a single enterprise, but the linkage of multiple enterprises. e convergence of various technologies within the enterprise alliance forms an intricate network, which brings advantages that a single enterprise cannot achieve. Technology convergence is an important means of enterprise alliance cooperation and a necessary prerequisite for the reengineering of production technology and process flow.

Knowledge convergence The various scientific reference and cooperation
Technology convergence The distance between applied science and technology is shortened Market convergence New product-market convergence Industry convergence Convergence of enterprises or industry sector

Production Convergence Subnetwork (Production Stage).
In the early stage of breakthrough technology development, it requires very high costs and R&D expenses. In many cases, although the technology is advanced, it does not conform to the expectations of the market, which is not cost-effective. Breakthrough technologies come to the forefront only when they become products that can be sold. e stage of production convergence is based on the interaction among the alliance enterprises and the alliance enterprises are scattered in different parts of the production chain, which constitutes the production convergence network for breakthrough innovation. Alliance enterprises in the network can be suppliers, producers, supporters of complementary infrastructure, or providers of production and supporting measures to meet the needs of breakthrough innovation productization. With the continuous development of information and production technology, "fragmented" production has become a new production mode for enterprises to exploit their strengths, circumvent their weaknesses, and expand their profits [21]. e emergence of the production division of labor makes it unnecessary for enterprises to undertake all production processes [22]. Alliance enterprises take advantages of alliance networks to speed up the development of new products and increase the possibility of breakthrough innovation products [23].

Market Convergence Subnetwork (Commodity Sales Stage).
e success of breakthrough innovation means the commercialization of commodities or technologies [24]. With the acceleration of scientific progress and technological innovation, enterprises face a tougher business environment and it is difficult for enterprises to realize breakthrough innovation through limited internal resources. It is the key path for many enterprises to realize the "last mile" of breakthrough innovation by breaking organizational boundaries, obtaining external resources, and building the market convergence network of alliance enterprises. McEvily and Zaheer pointed out that those enterprises can obtain valuable information, capture new business opportunities, and maintain sustainable competitive advantage through interorganizational networks [25]. Many enterprises construct enterprise alliance networks to develop markets and achieve breakthrough innovation [26]. As breakthrough innovation focuses on the development of new businesses and new markets, the enterprise skills required for its commercialization are different from those required in the rest of the stage, focusing on collecting and processing the information of customer requirement and competitor capability [27]. With the help of the marketing network and other resources of alliance partners, it is easier to convert technical resources into salable products and produce more marketable products. With the deep convergence of knowledge, technology, and production in the alliance enterprises in the early stage, the product categories of the enterprise are increasingly cross-border, the market boundary is gradually blurred, and the market of enterprise alliance forms convergence. Market convergence is a process in which the alliance enterprises contribute their own original market and create a new market, enterprises are increasingly connected, multiple parties share information resources, the scope of convergence is expanding, and the network structure is optimized, as shown in Figure 3.
Deep convergence of enterprise alliance for breakthrough innovation involves all types of activities inside the enterprise alliance, as well as the resources to support breakthrough innovation activities. It is an organic system composed of a knowledge convergence network, technology convergence network, production convergence network, and market convergence network. Deep convergence of enterprise alliance for breakthrough innovation has the characteristics of supernetwork, and the supernetwork structure model can be constructed, as shown in Figure 4. e deep convergence of enterprise alliance for breakthrough innovation is characterized by multiagent, multilevel, multiattribute, multicriteria, and other features, as shown in Table 2.  In a supernetwork, subnetworks are described by a "set of points," connected by edges or arcs between each "set of points." Supernetwork is composed of multiple subnetworks, and each subnetwork is a relatively independent subsystem, which influences each other through the connection between nodes Discrete Dynamics in Nature and Society 5 convergence supernetwork model of enterprise alliance for breakthrough innovation and has corresponding relationships, which is called a node in the model. i, j are the two nodes in the subnetwork as shown in Figure 5.

Construction and Analysis of Supernetwork
According to the relationship analysis of the model, this paper gives the following mathematical model: (1) In the knowledge convergence subnetwork, s ij is the level of knowledge flow between nodes i and j, values range from 0 to 1, the cost of each knowledge flow s ij is D ij � D ij (s ij ), income is W ij , and W ij � W ij (s ij ).
e competition and cooperation relationship in the breakthrough innovation enterprises alliance will lead to knowledge spillover risk in the process of cooperation, which is not conducive to knowledge sharing. As a result, the cooperation effect of breakthrough innovation enterprise alliance is unsatisfactory, so the establishment of knowledge flow s ij has certain risk X ij , and X ij � X ij (s ij ).
. e "ubiquitous innovation network" not only provides the enterprise alliance with rich resources for breakthrough innovation but also brings the risks of "loss of control" and "knowledge loss" to the enterprise alliance, so the establishment of technology flow h ij has certain risk R ij , and R ij � R ij (h ij ).
(3) In the production convergence subnetwork, technology is transformed into products to realize breakthrough technology materialization, i, j are two nodes, q ij represents the flow of materials among nodes, q ij is a comprehensive index of interenterprise relations, infrastructure conditions, exchange of production information, implementation and management degree of production, and standardization degree of production and manufacturing, values range from 0 to 1, the cost of establishing the flow of materials q ij is B ij , B ij � B ij (q ij , h ij ), benign materials flow q ij can gain income U ij , and U ij � U ij (q ij ), which is the revenue function q ij .
(4) In the market convergence subnetwork, i, j are two nodes, p ij represents the flow of market information between nodes, which is a comprehensive reflection of meeting customer needs, understanding the information of competitors, convergence of resources and capabilities, and marketization operation, the value of p ij is between 0 and 1, the cost of establishing the flow of market information p ij is A ij , A ij � A ij (p ij , q ij ), benign market information flow p ij can gain income V ij , and V ij � V ij (p ij ).
s ij , h ij , q ij , and p ij are the decision variable of the model and they are the comprehensive indicators, which need to be quantified. is paper constructs the four indicators based on relevant studies, as shown in Table 3. e construction of the above functions is based on the previous research on the deep convergence of enterprise alliances. For example, the cost of establishing market information flow in nodes is affected by p ij . Because production has an impact on the flow of market information, this paper considers that the cost of market information flow is the function of p ij and q ij . Similarly, the materials flow is affected by the technology flow, so the cost of materials flow is a function of q ij and h ij . At the same time, the "flow" in networks will bring some revenues, which will form the revenue function in different network systems. is paper assumes that all the functions above are continuous for the convenience of research. e goal of an individual in the supernetwork is the maximum revenue of knowledge flow, technology flow, (1) Suppose the weights of the above six objectives are α 1 , α 2 , α 3 , α 4 , α 5 , α 6 , α 7 and α 1 + α 2 + α 3 + α 4 + α 5 +α 6 + α 7 � 1. erefore, the objective function is shown in Model (2).
According to the theoretical analysis of supernetwork and the variational inequality, the optimal solution satisfying the above equation also satisfies the following variational inequality: For the convenience of the research, the hypothesis is as follows: e above variational inequality can be expressed in standard form: F(x * ), x − x * ≥ 0, F(X * ) � (F 1 (X * ), F 2 (X * ), F 3 (X * ), F 4 (X * )), X � (s ij , h ij , q ij , p ij ), and X * � (s * ij , h * ij , q * ij , p * ij ).
Discrete Dynamics in Nature and Society e supernetwork equilibrium model about deep convergence of enterprise alliance for breakthrough innovation is transformed into a mathematical model of a variational inequality, which is easy to analyze.

Solving and Analysis of the Supernetwork Equilibrium
Model.
e model is solved from a mathematical point of view. Formula (5) represents the marginal cost of the knowledge flow in the knowledge convergence network, formula (6) represents the marginal revenue of the knowledge flow in the knowledge convergence network, and formula (7) represents the marginal risk cost of knowledge flow in the knowledge convergence network.
When the marginal total cost of the knowledge flow multiplied by the corresponding weight is equal to the marginal revenue of the knowledge flow multiplied by the corresponding weight, knowledge flow reaches equilibrium; otherwise, it is not effective in maintaining such knowledge flow, as shown in the following formula: e marginal total cost of technology flow in the technology convergence network is shown in formula (9), formula (10) represents the marginal cost of technology flow in the technology convergence network, formula (11) represents the marginal cost of technology flow in the production network, formula (12) represents the marginal risk cost of technology flow in the technology convergence network, and formula (13) represents the marginal revenue of technology flow in technology convergence network.
When the above equilibrium solution is satisfied, all individuals i(i � 1, 2, . . . , k) obtain the maximum revenue. As a whole, the deep convergence system of enterprise alliance for breakthrough innovation has the greatest overall revenue under the current state. In the order to simulate the model proposed in this paper, the following assumptions are made.

Hypothesis 1.
ere are 3 individuals in the supernetwork system, which exist in the knowledge convergence subnetwork, technology convergence subnetwork, production convergence subnetwork, and market convergence subnetwork at the same time, and there is a one-to-one correspondence in the four-layer network.

Hypothesis 2.
e levels of knowledge flow, technology flow, materials flow, and market information flow are either positive or zero, and the negative case is not considered here; they are between 0 and 1, 0 ≤ s ij ≤ 1, 0 ≤ h ij ≤ 1, 0 ≤ q ij ≤ 1, 0 ≤ p ij ≤ 1.

Hypothesis 3.
e revenues, costs, and risks of individuals in the model can all be described by functions of corresponding parameters. In practice, the cost and revenues functions of individual i will be different in different subnetworks, Due to the fact that the knowledge flow s ij , technology flow h ij , materials flow q ij , and market information flow p ij among different individuals have different influences on individual i, they have different functional relationships. In order to facilitate the simulation, this article assumes that the cost, revenue, and risk functions of individual i are the same as those of other individuals in the same layer of the network, Individuals can be regarded as nodes in the network, for individual 1; s 11 , s 12 , and s 13 , respectively, represent the knowledge flow between this node and other nodes in the knowledge convergence subnetwork, revenue from establishing knowledge flow W 1j � 3 * sin(π/2s 1j ), the cost D 1j � �� � s 1j , and the risk X 1j � e s 1j . In the technology convergence subnetwork, h 11 , h 12 , and h 13 represent the technology flow between node 1 and other nodes, the revenue E 1j � 3 * sin(π/2h 1j ), the cost C 1j � �� � h 1j , and the risk R 1j � e h 1j . In the production convergence subnetwork, q 11 , q 12 , and q 13 represent the materials flow between node 1 and other nodes, the revenue U 1j � 2 * sin((3π/2) + πq 1j ), and the cost B 1j � 2q 1j /(0.1 + h 1j ) + 1.5 q 1j . In the market convergence subnetwork, p 11 , p 12 , and p 13 represent the market information flow between node 1 and other nodes, the revenue V 1j � 2.5p 1j , and the cost A 1j � 2 ��� p 1j . According to the requirements for knowledge value, technology value, product revenue, market revenue, risk, and cost of the system, different weights can be set to meet the actual requirements. In the simulation of this paper, the function does not have the meaning of the actual corresponding system, so for the convenience of simulation, the weight setting is not considered. In the practical application of the model, the weight can be set flexibly according to the actual requirements of the equilibrium operation about the deep convergence system of the enterprise alliance.

Model Simulation
Process. According to the above assumptions and model research, the mathematical model of the integrated structure is built.
e genetic algorithm tool in the MATLAB optimization toolbox is used for the simulation. e objective function is taken as the adaptive function, and the M file is compiled according to the objective function.

Analysis of Simulation Results.
e operation is stopped after 110 iterations, and the optimal value of the objective function is 2.012. It can be seen from Figure 6 that the iterative convergence of the model is faster, and the algorithm technology has strong operability and higher efficiency. e simulation results of the model show that the best level of knowledge flow should be 0.64, the best level of technology flow should be 0.85, the best level of materials flow should be 0.805, the market information flow is 1, and the overall income of individual 1 is the best. e optimal benefit of individual 1 in the system is 5.096, as shown in Figure 7.

Suggestions and Implications
6.1. Suggestions. Based on the specific numerical results obtained by model simulation and the previous analysis, this article can provide certain policy recommendations for the deep convergence system of enterprise alliance and build the deep convergence network of enterprise alliance. Enterprise alliance network has become an important way to promote enterprise innovation, and the construction of an enterprise alliance network is very important for enterprises to achieve breakthrough innovation. In order to obtain sufficient innovative resources such as knowledge, technology, production, and market, enterprises should change the practice of focusing on the development of a single field and build a whole convergence network process from creative development, breakthrough technology, production to sales, guided by market demand. It is necessary to promote the balanced flow of diversified and heterogeneous resources within the enterprise alliance network and accelerate the breakthrough innovation with the optimal enterprise alliance network relationship and strengthen and adjust the resource management of enterprise alliance. In the process of innovation, enterprise alliance should adjust resource allocation mode according to the developing situation and the macro environment and strategically build enterprise alliance network structure to ensure a diversified and lasting trust relationship in enterprise alliance, so as to obtain more abundant network resources, increase the stock of knowledge and technology in enterprise alliance, improve resource utilization efficiency, avoid the waste of resources caused by excessive flows, and enhance the level of resource flows in the deep convergence system of enterprise alliance. It is necessary to encourage core enterprises in enterprise alliance to open up innovation resources, promote cross-border convergence of different types of enterprises, guide collaborative innovation in the links about R&D, production, and market, strengthen enterprise alliance information sharing and technical exchange and business cooperation, expand communication channels of technology, production, and market, share all kinds of supply and demand information, and use big data and cloud computing technology to carry out in-depth information mining. In short, in different stages of the breakthrough innovation, the enterprise alliance should strengthen the information exchange among enterprises, integrate resources reasonably, and reach a consensus on cooperation, so as to achieve win-win benefits for all parties within the enterprise alliance.

Implications.
Breakthrough innovation is an important way for enterprises to obtain a sustainable competitive advantage, and an enterprise alliance network can promote enterprises to achieve breakthrough innovation. In this paper, the supernetwork theory is applied to construct supernetwork equilibrium model about deep convergence of enterprise alliance for breakthrough innovation. Based on the analysis of its structural relationship and balanced operation, the mathematical model of supernetwork equilibrium is given. is paper puts forward the optimization and management strategy of supernetwork equilibrium model about deep convergence of enterprise alliance for breakthrough innovation and then provides a reference for enterprise alliance to realize deep convergence and breakthrough innovation. In practice, the enterprise alliance should further promote the construction of the whole process convergence network from creative development, breakthrough technology, production to sales, promote the balanced flow of diversified and heterogeneous resources within the enterprise alliance network, and realize the breakthrough innovation with the optimal enterprise alliance network relationship. However, there are still some shortcomings in this study. In practice, the cost function, risk function, income function of knowledge flow, technology flow, materials flow, and market information flow are very complex and uncertain. For the convenience of the study, this paper assumes that the above functions are continuous. More factors can be considered to influence the supernetwork equilibrium model about deep convergence of enterprise alliance for breakthrough innovation.  14 Discrete Dynamics in Nature and Society
