Abstract: As an important factor in promoting economic development, investment has always been attached importance by all countries. Nowadays, with the rapid development of China's economy, many problems have gradually emerged behind the high prosperity of the economy. How to deal with the relationship between economic development and environmental protection is an urgent problem that has attracted more and more scholars' attention. In order to solve this problem, the theory of green investment has been concerned by the academic circles. Investment in the field of environmental protection, ecological construction and then promote the generation of green capital, and improve economic output have become factors that must be considered in the development process of countries. Under the background of the new industrialization road proposed by the state and the construction of comprehensive, coordinated and sustainable economic and social development, the study of green investment is more important. In view of the above background, this paper defines the scope of research as green public goods investment. Through theoretical research and empirical research, the efficiency of green public goods investment in China is analyzed. First of all, through theoretical research, combined with domestic and foreign literature, this paper defines the concepts of public product investment, investment efficiency, green investment, etc. On this basis, the connotation of green public product investment is summarized, that is, green public product investment consists of environmental pollution control investment and forestry investment. Secondly, by referring to the relevant yearbook, this paper describes the status quo of China's green public goods investment from 2000 to 2013 and briefly analyzes its development trend. At the same time, the time series ARIMA model is used to fit the development trend and forecast the total investment in green public goods in the next five years. In the empirical part of efficiency, the DEA method takes environmental pollution control investment and forestry investment as input variables and gross domestic product as output variables to measure investment efficiency, and finds that the investment efficiency has been decreasing year after year, and analyzes that it is caused by scale efficiency. Finally, this paper selects Tobit model, selects 8 influencing factors from three different aspects of industry, city and forestry for regression of scale efficiency, and obtains the main influencing factors of current efficiency.
