绿色生产技术、规模、管理与能源利用效率——基于全局DEA的实证研究

The Green Production Technology,Scale,and Management and Energy Efficiency——A Application of Global DEA

本文引入全局DEA和＂环境技术＂概念框架,结合方向距离函数和SBM模型来构造绿色生产率和能源利用效率指标,并运用面板数据计量分析方法实证研究绿色生产技术、规模、管理对中国能源利用效率的影响。结果表明：（1）2002~2011年间中国绿色生产率累积增长达9.79个百分点,技术进步、规模效率、资源配置效率对生产率增长的贡献率分别为265.57、-76.43、-89.14个百分点;（2）绿色生产技术、规模效率、管理水平以及煤炭占比、能源价格每提高1个百分点,能源利用效率分别提高0.4450、0.8099、0.9309、-0.2515、0.0390个百分点。由此可知,合理调整生产规模,提高规模效率,加快市场化改革,积极发挥市场在要素配置中的作用,提高资源要素配置效率是现阶段中国提高能源利用效率的重要出路。

By introducing the concepts of global DEA and ＂environmental technology＂, combining directional distance function and SBM model, this paper constructs the green productivity and energy efficiency indicators. On this basis, an econometric analysis of the impact of green production technology, scale and management on energy efficiency using provincial panel data. The results show that： （ 1 ） during 2002 - 2011, accumulation of China green productivity growth was 16.56%. Technical progress, scale efficiency and resource al- location efficiency contributed 265.57, - 89.63, and - 76.20 percent to productivity growth; （2） production technology, scale, and management level, coal proportion, and energy price increase by one percent, energy utihzation efficiency would increase by 0.4450, 0.8099, 0.9309, - 0.2515 and 0.0390 percent respectively. Combining with the previous results, we can obtain the conclusion that ad- jnsting production scale so as to improve scale efficiency, speeding up the marketization reform so as to improve the efficiency of resources allocation is thought to be an effective approach to improve energy efficiency.
