我国沿海11个省区市经济差异及影响因素分析

Analysis of economic differences and influencing factors in 11 coastal provinces,regions and cities in China

东部沿海地区是中国经济发展的重点地区,但其内部经济差异问题相当突出。为协调东部沿海地区的经济可持续发展,部分沿海省区市在2008年前后制定并实施了沿海发展战略。文章利用变异系数和基尼系数对11个沿海省区市2000-2020年经济差异变化进行探究,结果表明,区域经济差异在此期间总体呈现缩小趋势。其阶段性特征为:2000-2004年呈现缓慢上升趋势,2004-2014年总体为下降趋势,2014-2020年呈现回升趋势。然后文章利用面板数据模型对区域经济差异的影响因素进行分析,结果表明,存在沿海开发战略对11个沿海省区市经济差异存在正向影响。

The eastern coastal region is a key area for China's economic development,however.The issue of economic disparities within the eastern region is quite prominent.In order to coordinate the sustainable economic development of the eastern coastal areas,some coastal provinces,regions and cities formulated and implemented coastal development strategies around 2008.This article explores the changes in e⁃conomic disparities among 11 coastal provinces,regions and cities from 2000 to 2020 using coefficient of variation and Gini coefficient.The results show that regional economic disparities have generally shown a decreasing trend during this period.Its phased characteristics are:a slow upward trend from 2000 to 2004,an overall downward trend from 2004 to 2014,an upward trend from 2014 to 2020.Then,a panel data model was used to analyze the influencing factors of regional economic disparities and the results showed that the coastal development strat⁃egy had a positive impact on the economic disparities of 11 coastal provinces,regions,and cities.
