地区专业化与全要素生产率增长——基于中国农药制造业的实证研究

Study on the Regional Specialization & Total Factor Productivity——Based on Empirical Analysis of China' Pesticide Manufacturing Industry

为探寻提高我国农药制造业的地区专业化与生产效率增长的关系,分别运用区位熵测算了我国农药制造业的专业化水平,运用DEA的Malmquist指数方法测算了农药制造业的全要素生产率增长状况,结果表明:专业化水平对农药制造业生产率增长有显著的正向影响。地区专业化积极地促进了农药制造业生产率的增长,通过对技术进步和效率改善的回归来看,专业化主要通过效率改善来促进全要素生产率增长的。企业规模对全要素生产率的增长和技术效率的改善都有显著负面影响;对技术进步的变化也有负作用,但无统计上的显著性。资本密集度对TFP增长、技术效率改善均有显著正向影响。FDI对农药制造业的TFP增长、技术进步及技术效率改善等均无明显影响。产权结构显著地促进了地区的农药产业技术进步,但对TFP的增长、技术效率改善均无统计上的显著性。

The regional specialization and others factors affect the technological progress and the technical efficiency improvement and total factor productivity respectively,results show that,regional specialization degree of pesticide manufacturing has a positive impact on productivity growth,that is industrial concentration degree actively promotes productivity growth.From the result of the regression of the technical progress and improved efficiency,the specialization mainly affects the total factor productivity through the efficiency improvement.The scale of enterprise has obviously negative influence on total factor productivity growth and technical efficiency improvement,and also has negative effect on technological progress,but no statistically significant.RCL has significantly positive effects on TFP growth and technology efficiency improvement.FDI has no significant effects on pesticide manufacturing TFP growth,technology progress and technical efficiency improvement,etc.Property right structure（PSR）remarkably promotes the region＇s pesticide industry technology progress,but for TFP growth,technical efficiency improvement the effects were not significant.
