3.1 BPNN and enterprise technological innovation
The fully connected neural network is the simplest NN in DL [23, 24]. It can include multiple hidden layers, and each hidden layer can also include multiple neurons. It belongs to the feedforward neural network (FNN), the signal propagates in one direction, and there is no loop in the network. For the analysis of BPNN, it can be found that this is a multi-layer FNN, and its main characteristics are that the signal is forward-propagated, and the error is back-propagated. In the process of data transmission of BPNN, the first stage is the forward propagation of the signal, from the input layer to the hidden layer, and finally to the output layer. The second stage is the back propagation of the error, from the output layer to the hidden layer, and finally to the input layer, adjusting the weights and biases from the hidden layer to the output layer in turn, and from the input layer to the hidden layer. In BPNN, the calculation of the input vector X of the input layer, the output vector Y of the hidden layer and the output vector O of the output layer are expressed in equations (1) to (3) respectively:
$$\text{X}={\left[{x}_{1},{x}_{2},\dots ,{x}_{i},\dots ,{x}_{n}\right]}^{T}$$
1
$$\text{Y}={\left[{y}_{1},{y}_{2},{y}_{3},\dots ,{y}_{j},\dots ,{y}_{p}\right]}^{T}$$
2
$$\text{O}={\left[{o}_{1},{o}_{2},{o}_{3},\dots ,{o}_{k},\dots ,{o}_{q}\right]}^{T}$$
3
\(n,p, \text{a}\text{n}\text{d} q\) represent the number of neurons in the input layer, hidden layer and output layer respectively. For the data \({O}_{k}\) of the output layer node, the calculation is as follows:
$${O}_{k}={f}_{2}\left(\sum _{j=1}^{p} {w}_{k}{Y}_{j}-{b}_{k}\right)$$
4
\({w}_{k}\) means the output data of the hidden layer node, and \({Y}_{j}\) refers to the feedback error signal of the output layer unit. \({b}_{k}\) stands for the threshold of the network structure, and \({f}_{2}\) signifies the linear function of the upper layer input of the model.
The enterprise technological innovation method is studied using the DL algorithm. In the process of its reform, management is the human capital for the long-term development of an enterprise, and an important promoter to promote the blossom of new ideas and increase investment in technological innovation. In R&D activities, the government must not only understand market trends and consumer demands, but also monitor these activities, while bearing the consequences of R&D failures and the products entering the market. For the analysis of the structural network of enterprise technological innovation, the results are exhibited in Fig. 1:
3.2 Implementation of the dynamic mechanism model of enterprise technological innovation
The technological innovation capability of an enterprise is the foundation of its guarantee. At the same time, it is also the embodiment of enterprise technological innovation [25]. It includes innovative investment, innovative product productivity, and innovative product sales capabilities. The degree of support of enterprise technological innovation to promote the development of innovation activities directly affects the operation of its dynamic mechanism. In addition, market demand generates profits and drives the development of profitable markets. The government supports enterprises to increase investment in innovation, technology development, and modernization, and increase the production capacity of innovative products. With the successful sale of these products, the company has achieved excess profits. Profits intensify market competition, and market competition affects profit distribution.
Therefore, the operation mode of the dynamic mechanism of enterprise technological innovation can be summarized as, under the influence of external environmental factors, the external driving force (market demand driving force, market competition pressure, technology driving force, and government support force) directly or indirectly becomes its power source and supporting force around the profit-driving force of the enterprise. The innovation consciousness of enterprises can induce and expand this driving force. This kind of profit sensitivity can directly encourage enterprises to participate in technological innovation, or indirectly encourage scientific and technological personnel to participate in it through enterprise culture and internal incentive mechanisms. The technological innovation capability of the enterprise ensures the smooth progress of innovation activities. The latest technological innovation of the enterprise successfully feeds back its dynamic mechanism, stimulates new demands for innovation, and guides new activities. Figure 2 denotes the structure of the implemented innovation dynamic mechanism model:
3.3 Enterprise's innovation dynamic mechanism and technological reform
The structural analysis of the system is the basis of the research. As a system, the dynamic mechanism is composed of different subsystems in a certain form. It is characterized by the way that various elements are related to their own structural characteristics. The way enterprises participate in the reform of the incentive mechanism and technological innovation is not only the premise of the research, but also plays a significant guiding role in the whole research. The dynamic mechanism of enterprise shareholding itself is an extremely complex system and a complete whole. Hence, to analyze its internal operation law more comprehensively, it is divided into endogenous and exogenous dynamic systems. Among them, the endogenous dynamic system is an abstract concept on the basis of the interests of enterprises, and it is an organic combination that promotes enterprises to participate in the reform of organizational structure. As a for-profit organization, an enterprise must develop continuously under the influence of the market environment. It is an inevitable trend to generate demand in the process of domestic development. When a company's needs cannot be met through internal behavior, it seeks external help. Participating in the reform of the internal structure has become one of the means and channels to satisfy the demand. It can be seen that the driving force of the endogenous dynamic system comes from the practice of enterprise interest conversion. The essence of this process is the interaction and mutual promotion of many elements of the endogenous dynamic system. The analysis results of the influencing factors of the evaluation of enterprise innovation value are demonstrated in Fig. 3:
3.4 Analysis of edge cloud computing technology
In mobile networks, due to random changes in base station resource requirements, the relationship between the real world and the dynamic world tends to be complicated, and the deployment structure of edge cloud computing platforms will be constantly optimized. In order to solve the resource optimization problem of mobile computing platforms, a server implementation model based on uncertainty scheduling theory is implemented. As an overall optimization problem of mobile server resources with basic computing requirements, the real-time unification of network functions, storage resources, and users can be realized by using network devices. Edge cloud computing platforms are ubiquitous data reception centers that identify and process data by analyzing and interpreting it in the background. By implementing and coordinating solutions, incentives for technological innovation in enterprises can be effectively strengthened.
