中国八大区域经济发展质量的空间差异及其形成机制

Spatial Difference and Formation Mechanism of Economic Development Quality in China’s Regional Economies

基于新发展理念,以基本实现社会主义现代化远景目标为逻辑主线,从区域经济发展不平衡不充分的现实问题出发,构建涵盖创新驱动、协调发展、市场治理、绿色转型、开放经济和民生福祉等6个维度的经济发展质量评价体系,运用纵横向拉开档次法对2002—2018年中国八大区域经济发展质量进行动态评价,通过Dagum基尼系数和方差分解法剖析其空间差异并进行结构分解,提出“维度导向—目标识别—机制探测”的空间差异研究框架,揭示其空间差异的形成机制。研究发现:八大区域维度导向指数空间差异明显,沿海地区在各维度长期领先于内陆地区,但增速落后于内陆地区;区域经济发展质量指数增速稳定,呈现“东部沿海—南部沿海—北部沿海—东北—长江中游—黄河中游—西南—西北”依次减小的趋势;经济发展质量的空间差异以区域间差异为主,且呈现区域集聚的特征;经济发展质量的差异以开放经济和绿色转型为主,贡献率近60%;形成机制主要受制于协调发展、市场治理和绿色转型等维度,脱贫攻坚、创新投入、城乡协调和市场协调等目标层影响也较为显著。

Since the 19 th National Congress of the Communist Party of China,the important goal of China’s regional economic development is to effectively improve regional economic development quality and promote the coordinated development of regional economy.In this context,identifying the spatial differences of China’s regional economic development quality and its formation mechanism is of theoretical and practical significance for achieving this important goal.However,there are still some deficiencies in the existing literature on the connotation interpretation and spatial differences of China’s economic development quality,especially on the systematic research of the spatial differences and formation mechanism of regional economic development quality.Based on the new development concept,this paper takes the realization of the vision of socialist modernization as the logical main line,and starts from the practical problems of unbalanced and insufficient regional economic development to construct an economic development quality evaluation system,which covers six dimensions,namely,innovation-driven development,coordinated development,market governance,green transformation,open economy and people’s livelihood.In this paper,the vertical and horizontal scatter degree method has been adopted to dynamically evaluate the economic development quality in China and its eight major regions;and the Dagum Gini coefficient and the variance decomposition method is used to analyze the regional differences and structural sources.On this basis,the formation mechanism is revealed and explained based on the spatial differentiation research framework of dimensional orientation-target identification-mechanism exploration.The results show significant spatial differentiation in terms of different dimensional orientation indexs in eight regions,and the coastal areas have long been ahead of the inland areas in each dimension,but they lag behind the inland areas in terms of growth rate.The growth rate of regional economic development quality index is stable,and shows a decreasing trend as listed in the following sequence:east coast-south coast-north coast-northeast China-middle reaches of the Yangtze River-middle reaches of the Yellow River-southwest region-northwest region.Inter-regional differences are the main contributors to the difference in spatial economic development quality,and show the characteristics of regional agglomeration.The structural sources of spatial differences are mainly open economy and green transformation,with a contribution rate of nearly 60%;the formation mechanism is mainly subject to dimensions such as coordinated development,market governance and green transformation,as well as factors such as poverty alleviation,innovation investment,urban-rural coordination,and market coordination.This paper contributes to the existing literature in two aspects.First,this paper clarifies the logical main line of economic development quality under the current development objectives and practical problems,so as to realize the unity of its connotation in depth and breadth.Specifically,based on the new development concept,this paper takes the basic realization of the long-term goal of socialist modernization as the logical main line,redefines the connotation of economic development quality from the reality of the current unbalanced and insufficient regional economic development.Second,this paper identifies the spatial differences and structural sources of regional economic development quality from a systematic perspective,and then reveals the formation mechanism of spatial differences through the research framework of dimensional orientation-target identification-mechanism exploration.This paper,to a certain content,reveals the spatial differences and formation mechanism of China’s regional economic development quality from a systematic perspective,which helps the government departments formulate a comprehensive improvement scheme of economic development quality according to the heterogeneous evolution characteristics of economic development quality of different regions,and provides policy support for the coordinated improvement of regional economic development quality.
