我国区域生产效率及其影响因素实证分析——基于2001-2008年省际面板数据与随机前沿方法

Regional production efficiency and its influence factors analysis in China-Based on 2001-2008 inter-provincial panel-data and SFA method

运用随机前沿C-D生产函数,通过对全国和三大区域分别建模,对我国各地区的生产效率及其影响因素进行了分析.实证结果表明:生产效率区域格局为:东部大于中部大于西部;生产效率变化率的区域特征为:中部大于西部大于东部,中西部与东部生产效率差距逐步缩小;各模型一致表明,对外开放程度与基础设施的实际有效利用对生产效率变化具有普遍积极的作用;产业结构优化对东西部生产效率的边际效应最为显著;对中部而言,科技创新投入的作用最为突出.

With the use of SFA and the C-D production function,and models respectively for the nation and three regions,the author analyzes the regional characteristics of production efficiency of various regions in China and the influence factors of production efficiency.The empirical results show that the regional pattern of production efficiency：Eastern〉Central〉West;the regional characteristics of the change rate of production efficiency：Central〉West〉East,the gap between Central and West with Eastern is narrowing; All models consistently show that openness and effective and efficient use of infrastructure all have general positive effect on productive efficiency;Optimum of industrial structure has the most significant effect on marginal productivity to Eastern West;while the role of technological innovation is most prominent for Central.
