基于随机前沿的中国勘察设计行业效率影响因素分析

Analysis of China’s Engineering Survey and Design Industry Efficiency Influencing Factors Based on SFA

摘要:

对中国31个省市自治区2006-2011年工程勘察设计行业投入产出面板数据，采用随机前沿分析方法测定各省市行业生产效率及其变化，并对影响行业非技术效率的因素进行了定量计算和回归分析。结果表明：产出函数的技术非效率项对产出具有显著的影响，市场化程度、执业注册人数占比和规模经济同技术非效率项之间存在负向关联，而科研投入和中高级职称人数占比则对技术非效率项具有正向影响；该行业劳动力投入产出弹性（0.6721）远大于资本投入的产出弹性（0.4403）。

Abstract:

In this article the panel data of input-output of engineering survey and design industry in 31 provinces of China from 2006-2011 were analyzed by SFA and the technical efficiency and its variation of the industry of each province was evaluated. And non-technical factors that affect the efficiency of the industry were conducted a quantitative calculation and regression analysis. The results showed that: technical inefficiency outputs function has a significant impact on output, the introduction of technical inefficiency term is very necessary. There is a negative correlation between the technical inefficiency term and the variables that On behalf of the degree of market (Z1), certified enrollment proportion (Z3)and scale economies (market capacity) (Z5);and There is an active correlation between the technical inefficiency term and the variables that On behalf of the Research investment (Z2) and the percentage of senior titles. The industry output elasticity of labor input (0.6721) is much larger than the output elasticity of capital investment (0.4403).
