In the stock market of China, the rights and interests of small- and medium-sized investors are frequently encroached upon. This criticism makes it an urgent task to effectively restrain the large shareholders and the insiders of the listed companies on the wealth and theft of small and medium investors. The trading data of listed companies show the characteristics of exponential explosion, rapid disclosure of information, and increasing information collection channels. Therefore, in this paper, the BP artificial neural network in data mining was introduced to study the proportion of dividend distribution and equity management. Based on the analysis of the principle and implementation process of BP neural network, the algorithm model was further optimized and updated, establishing a dividend policy identification model with the purpose of protecting the interests of small- and medium-sized investors. The simulation results show that this research has opened up a new research path for the small and medium investors’ equity interests and related policy research.

Although the domestic stock market has been developing for decades, the mechanism of dividend policy is still a stumbling block to the development of the stock market (Ernayani R et al. 2017) . The irregular fluctuations and ups and downs of relevant policies in the stock market, the unrestricted dividend distribution of the listed companies, the characteristics of low dividend payback, or higher non-violation of dividends, greatly affect the healthy and sustainable development of the stock market and hit the investor’s investment confidence and enthusiasm. In order to protect the rights and interests of small and medium investors who are in a weak position in the stock market, a good atmosphere and environment must be established for the management of stock market investment with Chinese characteristic (Chen Q et al. 2017) . Although in recent years, the national legal level, the introduction of the LLSV index system has a clear evaluation and management of investor rights and interests. Internationally, the law and regulations are also advanced. Within the listed companies, there is no effective maintenance of the rights and interests of small and medium investors, and even some companies are still trying to avoid the legal rights and interests of legal compliance (Nielsen T et al. 2016) . In particular, the large shareholders in the listed companies are often more rapid and ahead of the company’s information sources. In this convenient condition, the large shareholders adopt various kinds of practices of irregularities for favoritism and occupy the “oil and water” of small and medium investors from various levels (Zhang Z et al. 2016) . Many scholars have studied the stock market data of the past 10 years, and found that in the listed companies with the same dividend distribution, the more the ownership of the stock, the announcement of the dividend policy will be more welcomed by the investors (Qiu C et al. 2016) . When the listed companies carry out the same dividend distribution, the more the mutual supervision and restriction among all the shareholders is standardized, the more successful the dividend policy is to get the good evaluation of the investors (Yang B et al. 2016) . Under the support of this research result, the research on the interaction mechanism of dividend distribution and equity proportion is not only very necessary, but also has a positive scientific guidance role.
2 State of the art
The popularity of wireless network also promotes the prosperity of domestic stock market and ushering in new development space. With the exponential increase of Internet data, the channel for small and medium investors to get dividend policy is wider and more efficient. In this paper, the BP artificial neural network in data mining is introduced to establish a dividend policy identification model for the purpose of protecting the interests of small and medium investors, which explore a new way for the study of equity interests and related dividend policies for small- and medium-sized investors. The study of artificial neural networks began in the 40s of last century, which was originally used to study the function of the brain and the electrophysiological function of neurons. The initial mathematical model is a form neuron (Ji H et al. 2017) . Neural network is composed and connected by many simple neurons. The combination of different rules can form a neural network with different structure and complexity. The non-linear characteristics of this network can achieve parallel and adaptive processing, which has great structural and algorithmic advantages in the operation of complexity understanding (Gao H et al. 2017) .
The neural network is also a bionic model, which can simulate the function of the human brain neural system and can realize the same function as human, such as the ability of storing and processing information, the ability to analyze and processing, and the function of simplifying, summarizing, and simulating the information, making this algorithm more intelligent. Neural network uses a large number of neuron nodes to represent the structure and function of human brain. Use inductive learning method and large-scale empirical research to repeat learning. In the process of continuous adaptation, the weights of the interconnections between the neurons are corrected, so that the mutual structure and weights of the neural network are distributed steadily. The whole process is the learning process of human knowledge acquisition (Yang W R et al. 2016) . From the current statistical data, most of the neural network models are based on BP neural network. The BP neural network adapts to the change of the system by learning autonomously to change the connection value of the internal network, which has better fault tolerance and robustness. The multi input and output structure model can be better used to study and analyze the system parameters of multivariable (Guanzhou D U et al. 2017) .

So how many hidden layers need to be determined through experiments.
3.2 Optimization strategy of BP artificial neural network
In order to solve the problem that BP neural network is not easy to be determined by network structure, it is easy to cause local minimum and so on. In this paper, genetic algorithm is introduced to optimize it to improve the performance of neural network. Genetic algorithm has great advantage in global search. Based on population, it uses individual fitness as a standard to judge the subsequent legacy operation. Genetic algorithm not only has good global search ability, but also improves the local search ability in the presence of mutation operator. The main forms of genetic algorithm for neural network optimization are as follows: first, optimize the topological structure of each layer in the neural network and the various parameters of the neuron. In order to solve the problem that the hidden layer and node number of the neural network cannot be accurately determined, the genetic algorithm is used to optimize the topology structure and then the network parameters are optimized. Second, if the neural network structure is clear, the genetic algorithm is used to update the threshold and weight of the neural network.
4 Result analysis and discussion
In order to verify the research on the share distribution and policy based on BP neural network, the relevant data of the listed companies of steel industry from 2010 to 2017 are selected to carry out the simulation experiment. The database from 2010 to 2015 served as training data. Using 2016 to 2017 data as test data, the accuracy of neural network is evaluated. First, the model design is carried out. The related parameter design is that the transfer function of the hidden layer and the output layer uses the Tansig function, the training function is purelin function, the actual interval is set to 16, the learning rate of the network is 0.0012, the maximum training time is 360 times, the target error is 0.6*10^ (− 11).

As an evaluation model, BP neural network performs accurately, qualitatively, and efficiently, making it very capable of dealing with nonlinear problems. As an important representative of the efficient mathematical model, the model has made positive contributions to the management of all aspects of human society. Therefore, in this paper, BP neural network mathematical model is proposed using to study the proportion of dividend distribution and equity management. After in-depth analysis of the structure of BP neural network, it leads to over fitting phenomenon for the network to determine weights and thresholds randomly. Human factors affect the number of nodes, which bring about long network learning time, too many iterations and poor learning rate. The optimization is carried out to improve the accuracy and efficiency of the BP neural network prediction model. The weights of isoparametric values are improved to optimize the structure of BP neural network. The network learning rate formula is improved to help the network reduce the correction and overcome the slow convergence of the algorithm. The genetic algorithm is introduced to update the algorithm flow. After improving the performance of neural network, the optimized BP neural network is simulated. From the result of verification, the evaluation model based on BP neural network is successful and can help small and medium investors effectively identify dividend policies of listed companies. However, there are still some improvements in this study. The next step is to further study the prediction accuracy of neural models.
