Abstract: Based on the environmental protection investment and social responsibility of the food industry, this paper adopts the relevant environmental protection information listed by the companies in the food industry in 2000-2015,and attempts to analyze the comprehensive impact of the external environment and internal management of the enterprise on the environmental protection. Results show that the ownership centralism oflisted companies, the basic earnings per share and strategic attitude are positively related to the environmental protection investment. So is the relationship between government subsidies and environmental visits that enterprises receive and the environmental protection investment. The external environment regulation of the listed company has negative influence on its environmental investment.
