Abstract:Fostering and developing emerging industries of strategic importance is the focus to promote China to accelerating the transformation of economic development mode, adjusting and optimizing the economic structure. Meanwhile the fiscal support for the development of emerging industries of strategic importance is meaningful. Based on the DEA efficiency measurement of Guangdong emerging industries of strategic importance, this article builds a Tobit model to analyze the impact factors of fiscal support efficiency. The empirical results show that the lower mean of scale efficiency is the cause of why the overall efficiency is low, besides fiscal subsidies, tax incentives and government procurement is helpful to improve the efficiency of fiscal support, but the effect of fiscal subsidies is the most obviously. Therefore, the market-oriented means should be used to improve fiscal supporting efficiency, in order to recycling of funds. Also in different stages of emerging industries of strategic importance, different means of fiscal support should be adopted.
