需求引致增长、结构增长与中国空间不平等

Demand-Led Growth,Structural Growth and China's Spatial Economic Inequality

本文将区域邻接关系引入传统基尼系数,构建了空间基尼系数指标,并基于地级区划数据测度了中国省域的空间基尼系数,以反映中国空间不平等水平。同时,将区域之间的商品贸易分解为需求引致增长和结构增长,基于2006—2020年有关数据,采用空间计量技术考察了需求引致增长和结构增长对省域空间基尼系数的影响。结果表明,商品贸易的需求引致增长会促进省域空间基尼系数上升,但是结构增长会抑制省域空间基尼系数上升,整体上结构增长的抑制作用大于需求引致增长的促进作用,兼具短期和长期效应。运用共同因子法处理需求引致增长、结构增长与空间基尼系数之间的内生性之后,结果具有较强的一致性和稳健性,且空间不平等具有时空维度的循环因果累积效应。因此,本文的研究结论对实现区域经济全面协调发展具有启示意义。

This paper introduces the regional adjacency relationship into the traditional Gini coefficient,constructs the spatial Gini coefficient index(SpGini),and measures the level of inequality in China's spatial economy based on prefecture level zoning data.At the same time,the commodity trade between regions was decomposed into demand-led growth and structural growth.Based on relevant data from 2006 to 2020,spatial econometric techniques were used to examine the impact of induced growth and structural growth on the provincial spatial Gini coefficient.The results indicate that demand-led growth caused by commodity trade will promote the increase of provincial spatial Gini coefficient,but structural growth will inhibit its increase.Overall,the inhibitory effect of structural growth is greater than the promoting effect of demand-led growth,and it has both short-term and long-term effects.After using the common factor method to handle the endogeneity between demand-led growth,structural growth and spatial Gini coefficient,the results show strong consistency and robustness,and spatial inequality has cyclic causal cumulative effects in terms of spatiotemporal dimensions.Therefore,the research conclusion of this article is beneficial for achieving comprehensive and coordinated development of regional economy.
