区域差异是由于自然资源、不同的区位、技术差异(包括基础设施)、人口等因素所形成的经济社会发展差异。区域差异是我国区域经济和县域经济发展水平差异的主要原因。因此,缩小我国东西部差距,实现区域经济的均衡发展和壮大县域经济,必须缩小区域差异,才能缩小区域经济发展的差距。 Regional differences are due to differences in economic and social development resulting from natural resources, different geographical locations, technological differences (including infrastructure) and population. Regional differences are the main reasons for the differences in the level of economic development between the regional economy and the county in our country. Therefore, narrowing the gap between eastern and western China, achieving balanced development of regional economy and expanding county economy, we must narrow the regional differences in order to narrow the gap in regional economic development.
