本文采用改进的Malmquist-Luenberger生产率指数对“十一五”期间（2006-2010年）中国制造业的绿色生产率增长进行测度。本文采用三阶段数据拟合分析模型，对政府措施对绿色生产率增长的影响进行了测度。主要结果如下：（i）Malmquist生产力指数的平均值为1.045，考虑到CO2排放量的Malmquist-Luenberger生产力指数的平均值为1.027。这意味着前者相对较高的价值是以大量的能源使用和CO2排放为代价的;（ii）中国的节能政策和措施，如大规模推广和采用节能技术，关闭和淘汰落后产能，减少产能过剩，对绿色发展至关重要;（3）在剔除环境影响和统计噪声对产出松弛的影响后，调整后的绿色生产率变化小于相应的初始水平，而调整后的技术变化大于相应的初始水平;（iv）中国制造业实施的节能政策远未达到最佳水平，更严格的执行将有利于制造业的绿色生产力增长。(C)2016爱思唯尔有限公司版权所有
This study introduces an improved Malmquist-Luenberger productivity index to measure the green productivity growth of China's manufacturing sector during the 11th Five-Year Period (2006-2010). A three-stage data envelopment analysis model is adopted to measure the effects of government measures on green productivity growth. The main results are: (i) the average value of the Malmquist productivity index is 1.045 and the average value of the Malmquist-Luenberger productivity index accounting for CO2 emissions is 1.027. This indicates imply that the relatively higher values of the former are at the expense of substantial energy usage and CO2 emissions; (ii) China's energy-saving policies and measures, such as mass promotion and adoption of energy-saving technology, closure and elimination of obsolete production capacity, and reduction of over-capacity are important for green development; (iii) after eliminating the effects of environmental influences and statistical noise on output slacks, the adjusted green productivity changes are smaller while the adjusted technical changes are larger than the corresponding initial levels; (iv) the energy conservation policies implemented in China's manufacturing sector are far from the optimal level, and more stringent enforcement would be conducive for green productivity growth in the manufacturing sector.
