中国工业增长质量的区域差异研究———基于绿色全要素生产率的收敛分析

The Research on Growth Quality Difference of China's Regional Industry ——Based on Convergence Analysis of Green Total Factor Productivity

经济增长质量反映增长的优劣程度。笔者运用SBM方向性距离函数和Luenberger生产率指标测度了过去10年30个省市工业部门包含了能源消费和污染排放的绿色全要素生产率,并将此作为各地区工业增长质量的度量指标,研究区域工业增长质量的差异。研究结果发现,我国东中西三大区域的工业增长质量呈梯度分布趋势,但界限已不再明显;三大区域中,东部地区工业增长质量呈现明显的俱乐部收敛特征,东部各省份工业增长质量差异随时间推移逐步缩小,而全国总体及中西部地区工业增长质量差距呈扩大趋势;全国总体及东中西三大区域工业增长质量存在条件收敛,对外开放水平和环境规制程度对区域工业增长质量差异的缩小起促进作用。

This paper researches the difference of regional industrial growth quality by calculating green total factor productivity about 30 provincial industrial sectors including energy consumption and pollution emissions with SBM directional distance function and Luenberger productivity index over the past ten years. The research results show that： The industrial growth quality about three areas of east, middle and western present gradient distribution trend with less obvious boundaries. Among the three areas, the industrial growth quality of eastern region present club convergence obviously, while the middle and west region show enlarge trend; The regional indus- trial growth quality about east, middle, western and the overall present conditional convergence, and the level of opening up and envi- ronmental regulation narrow the difference of quality about regional industrial growth.
