运用数据包络(DEA)方法测算了2000～2008年环境规制下中国西北五省区工业全要素生产率及分解指标值,结果为:全要素生产率整体水平低,低于全国的平均水平;技术进步对TFP增长的贡献大于效率变动贡献;规模效率水平高于技术进步水平。视环境规制强度、企业规模变化和研发支出强度为影响全要素生产率的主要因素并进行回归分析,结论为:环境规制强度提高1%,导致西北地区工业全要素生产率下降0.038%,技术效率下降0.076%,但能促使0.043487%的技术进步水平提高。在实证分析的基础上得出了较为客观的结论。
The DEA method was used to calculate the total factor productivity and the decomposition index value of the five provinces and autonomous regions in Northwest China from 2000 to 2008. The results showed that the overall level of TFP was low and below the national average, and the technological progress Contribution to the growth of TFP is greater than the contribution of efficiency changes; the level of efficiency is higher than the level of technological progress. According to the intensity of environmental regulation, the change of firm size and the intensity of R & D expenditures as the main factors that affect TFP, regression analysis shows that the increase of environmental regulation intensity by 1% leads to a decrease of 0.038% in industrial TFP and a decrease of 0.076 in technical efficiency %, But can promote the level of technological progress of 0.043487%. On the basis of empirical analysis, we come to a more objective conclusion.
