Abstract: The research on the input-output efficiency and influencing factors of forestry ecological security is conducive to rationally allocate the resources of the forestry ecological security construction and the promotion of the symbiotic development of forestry ecology industry system. Based on the spatial-temporal analysis of forestry ecological security efficiency of 31 provinces in China from 2005 to 2014 by using DEA-SBM model and Malmquist index model, the influencing factor system of forestry ecological security efficiency is constructed by using PSR model and regression analysis is carried out by using Tobit model. The results show that the development of forestry industry depends more on the expansion of scale than on the improvement of technical level, which is not conducive to the sustainable development of ecological security. Because the dynamic fluctuation of the efficiency of forestry ecological security is large and the index of technological progress is low, it is difficult to coordinate the development of forestry ecology and forestry industry. In the influencing factor system of forest ecological security efficiency, urbanization level, forest growth and decline ratio, ecological forest area, forest accumulation per unit area, environmental protection and ecological construction fiscal expenditure play an obvious role in improving the efficiency of forest ecological security; the total amount of per capita resources, the intensity of scientific research investment have a greater impact on the development of forest ecological security. Finally, the paper puts forward some countermeasures, including optimizing the structure of forestry industrial to promote the intensive and efficient development of forestry industry, strengthening innovation and improving technical efficiency to promote the integrated development of forestry ecology and industry, realizing the coordinated development of the total amount of forestry resources and the construction of public ecological culture.
