摘要
运用基于跨期生产前沿的SBM-DEA模型测算了中国省际1999—2012年的绿色发展效率,对中国绿色发展效率的演变特征与区域差异进行了考察,并对其收敛性进行了检验。研究发现,中国省际绿色发展效率水平不高,总体呈"先降后升"的演变趋势,且节能减排无效率是绿色发展无效率的主要来源;东部在样本初期没有显著拉大与中西部的绿色发展效率差距,而始于1999年实施的区域协调发展战略和2006年以后严格推行的节能减排政策在高新技术产业向东部集聚和高耗能高污染产业大量内迁的双重影响下,却引致东部与中西部的绿色发展效率呈现出严重的两极分化格局;中国省际绿色发展效率不存在显著σ收敛和绝对β收敛,但存在显著条件β收敛,而东中西三大区域呈现出典型的"俱乐部收敛"特征,说明由于三大区域之间的绿色发展效率差异在不断增大,导致中国省际绿色发展效率差距在逐步扩大,并没有朝完全相同的稳态水平收敛趋同,然而各个区域内的绿色发展效率差距在逐步缩小,并以不同的收敛速度向各自不同的稳态水平趋近。
The paper estimates the green development efficiency of China's provinces from 1999 to 2012 based on the intertemporal frontier SBM-DEA, analyzes the evolution features and regional disparity of China's green development efficiency, and empirically testes its convergence. Our study finds that: (1)the green development efficiency of China's provinces is at a low level, its trend shows "descend first and then ascend" on the whole, and the inefficiency of energy saving and emission reduction is a main reason for green development inefficiency; (2)The eastern region does not make its green development efficiency significantly higher than that in the mid-western region atthe beginning, however, the regional balanced development strategy since 1999 and energy conservation and emission reduction policy since 2006 have greatly changed the polarization pattern of green development efficiency between the eastern region and midwestern region; (3)No significant o convergence and unconditional β convergence exist in the green development efficiency of China's provinces, but conditional β convergence exists and the three major regions present a typical"club convergence" feature, which implys that the gap in the green development efficiency of China's provinces is gradually expanding, and the increase of regional differences is the main reason, the green development efficiency of China's provinces doesn't converge to the same steady-state level, but three regions will converge to their own steady-state level at different speeds.
