黄土高原地区县域经济发展的时空异质性及主要驱动力

Unbalanced economic growth is a ubiquitous phenomenon while investigating the regional development at a large spatial scale.Therefore,it is of great significance to analyze the spatio-temporal pattern of regional economic growth and the drivers to understand and facilitate the economic development of low development areas.Taking a county as a fundamental study unit,we used the county-level per capita GDP data on the Loess Plateau from 2005 to 2017,and geographic variables such as slope,elevation,and population density to analyze the spatio-temporal differences and the driving factors of the county-level economic development in the Loess Plateau by employing both conventional and advanced quantitative methods including Exploratory Spatial Data Analysis(ESDA)and the geographic detector model.Our results suggested that:(1)The selected indicators,including absolute difference,the fluctuation of relative difference and total difference of economic development on the Loess Plateau,all show steady increasing trends,respectively.(2)There are 64.5%of the counties with economic development being below the average level of the whole Loss Plateau region.The relatively high developed counties are distributed in the"A"-shaped regions in Inner Mongolia Autonomous Region,Shaanxi,and Henan provinces,however,the low development counties are mainly located in the"V"-shaped regions in Gansu and Shanxi provinces.(3)GDP,investment in fixed assets and urbanization rate are the major driving factors influencing the regional economic development,and the combined effects are far greater than that of any individual factor.

Comparison and Measurement of Economic Growth in Coastal Areas and Inland Provinces of China

This study aims to measure the regional difference in economic growth and the driving effect of export of coastal areas for inland provinces in China from the perspective of labor division.Embedded input and output data are adopted on the basis of the input-output theory for economic growth and trade accounting.Since China’s accession to WTO,vertical specialization across areas has been improved in general,but the areas differ widely in their participation in labor division in the global value chain(GVC)and national value chain(NVC).Different areas in China mainly rely on local production for economic growth,but engagement in GVC and NVC labor division is the major driver for the country’s rapid economic growth.Under the external impact,local economic growth has relied less on the outside,but more on local production since 2008.The driving effect of export of coastal areas for inland provinces is mainly reflected in agriculture,indicating that inland provinces and cities indirectly participate in international division of labor mainly by providing raw materials for production for eastern areas.This study,based on GVC and NVC integration and interaction,conducts in-depth research on the driving effect of export of coastal areas for the economic development of inland provinces,and offers a new perspective for studying the regional difference in economic growth in China.
