Study on the Influential Factors of Technical Efficiency Difference among Provinces of China----Based on Stochastic Frontier Analysis

This paper uses stochastic frontier analysis to make empirical study on the influential factors of technical efficiency difference among provinces of China. We find that the technical efficiency of every province gets steady increase from 1992 to 2003, but the difference among provinces is great. The development degree of non state-owned economy, foreign direct investment (FDI), the amount of imports and exports, and the region character all influence the technical efficiency. When the percentage of non state-owned economy in the total economy increases by 1%, the technical efficiency will increase by 0.4636%. When the percentage of FDI to GDP increases by 1%, the technical efficiency will increase by 3.4624%. When the amount of imports and exports increases by 1%, the technical efficiency will increase by 4.6549%. Under the situation of equal other condition, the technical efficiency of the eastern region is higher than that of the middle and western region of China
