RESEARCH ON ENTERPRISE ECONOMIC BENEFIT AND SAFETY INVESTMENT DECISION.

Coal, as a key input factor to ensure China's economic growth, plays an important role in the orderly development of its industry. The safety guarantee of production link is the only way to ensure the stable development of the industry, so it is in urgent need of the investment of safety funds and effective implementation to protect it. As a high-risk industry, the coal industry has a poor working environment, difficult working conditions, backward safety technology, and endless hidden dangers. In the process of development, the coal industry blindly pursues benefits, while ignoring safety investment, which is exactly a common problem in China's coal enterprises and also the deep cause of coal mine safety accidents. This paper uses relevant theories to analyze the effect of coal enterprises' safety investment on economic benefit and determine its equilibrium point of safety and economic benefit. On micro level of building model, neural network model for coal enterprise economic benefit is explained variable, safety input as explanatory variables, core number of coal production, labor, labor productivity, and fixed assets and intangible assets investment as a intervening variable, such as inspection cause nonlinear relationship between safety investment and economic benefit are intermediary variables, to measure the influence of different variables on economic benefit enterprise security mechanism, which integrated the result of theoretical analysis and empirical research, puts forward coal enterprises safety investment economic efficiency maximization of promotion strategy.
