制度环境与我国地区工业生产效率分析——基于面板随机前沿模型

Accounting for Environmental Influences on Industrial Production Efficiency of China in Stochastic Frontier Models

文章采用面板随机前沿模型,同时用市场化指数来衡量不同地区的制度环境,分析了我国的工业生产率。结果表明:资本的边际报酬显著为正,劳动要素投入偏多导致其边际报酬较低甚至为负;制度环境的改善可以促进工业增加值的增长和提高生产效率;时变模型表明我国地区生产效率伴随着时间的推进而显著提升。整体上看,中部地区的生产效率最高,西部次之,东部的生产效率最低,但是东中西间差异并不明显。文章据此提出了相应的政策建议。

In this paper, a panel stochastic frontier model is adopted, and the institutional environment of different regions is measured by the market index,and the industrial productivity of the 30 regions in 1999-2009 is analyzed.The results show that the marginal returns of capital is positive and significant,the marginal returns of labor is low or even negative;the improvement of institutional environment can promote the industrial added value growth and improve the production efficiency;time-varying model shows that China＇s regional production efficiency increased with the growth of time.On the whole,the productive efficiency of the central region is the highest,while the west is the lowest,but the difference between East and West is not obvious.
