高质量发展背景下中国省域绿色经济效率与社会公平绩效耦合性研究

Study on the Coupling between Provincial Green Economic Efficiency and Social Equity Performance in China under the Background of High-Quality Development

运用包含非期望产出的超效率数据包络法(US-SBM)和熵权法,对中国2008—2019年30个省份的绿色经济效率与社会公平绩效进行了测度,借助偏离系数的耦合度模型以及面板Tobit模型等方法,从省域层面探究了两者耦合度的动态演进规律并阐明了耦合机理与驱动机制。研究发现:全国绿色经济效率总体呈现出先下降后上升的趋势,且具有地区非均衡的特征,而各省份的社会公平绩效水平随着时间推移呈现出稳步提升的态势,绿色经济效率与社会公平绩效两系统耦合度保持稳定上升的趋势。大部分省份的耦合度变异系数呈现出先下降后上升的规律,其中东部地区的耦合度变异系数普遍高于其他地区;各省份耦合度的类型演变总体上以保持原有类型向相邻类型演变为主,在观察期后期仍有近1/3的省份处于初级以下的协调发展类型。在驱动因素探讨中,产业结构、财政分权、科技创新、对外开放以及环境规制均对两系统及其耦合度具有显著正向影响,而城市化率对耦合度的增长存在抑制作用;在分样本检验中,各要素对东部地区耦合度的影响效用更强。

Using super efficiency data envelopment analysis including unexpected output(US-SBM) and entropy weight method, this paper measures the green economic efficiency and social equity performance of 30 provinces in China from 2008 to 2019. With the help of the coupling degree model of deviation coefficient and panel Tobit model, this paper explores the dynamic evolution law of their coupling degree from the provincial level, and expounds the coupling mechanism and driving mechanism. The results are as follows. The overall efficiency of the national green economy shows a downward trend first and then an upward trend, and has the characteristics of regional imbalance. The social equity performance level of provinces shows a steady upward trend over time, and the coupling degree of the two systems maintains a steady upward trend. The coefficient of variation of coupling degree in most provinces shows the law of first decreasing and then increasing, and the coefficient of variation of coupling degree in the eastern region is generally higher than that in other regions. The type evolution of the coupling degree of each province mainly maintains the evolution from the original type to the adjacent type. In the later stage of the observation period, nearly one third of the provinces are still in the coordinated development type below the primary level.In the discussion of driving factors, industrial structure, fiscal decentralization, scientific and technological innovation,opening to the outside world and environmental regulation aa have a significant positive impact on the two systems and their coupling degree, while urbanization rate has an inhibitory effect on the growth of coupling degree. And in the sub sample test, each factor has a stronger effect on the coupling degree in the eastern region.
