政府补贴、区域一体化与西部地区经济高质量发展——基于企业异质性的新经济地理学理论

Government Subsidies,Regional Integration and High-quality Economic Development in Western China——New Economic Geography Theory Based on Enterprise Heterogeneity

以新经济地理学理论为基础,在空间视角上探讨政府补贴是否有效推动西部地区经济高质量发展。研究表明,区域一体化水平是影响政府补贴发挥政策效应的门槛变量,当区域一体化水平较低时,政府补贴不能有效促使企业转移到西部地区。而当不同企业对政府补贴反应异质性时,政府补贴不能有效促进高效率企业率先转移到西部。实证研究表明:区域一体化促使政府补贴发挥政策效应存在临界值,当区域一体化水平大于该临界值时,政府补贴才对企业转移发挥显著作用。只有持续推动区域一体化发展且继续加大对西部地区企业补贴力度,才能有效推动西部地区经济高质量发展。

Based on the theory of new economic geography,this paper explores whether government subsidies can effectively promote the high-quality economic development in the western region in China from a spatial perspective.The research shows that the level of regional integration is the threshold variable that affects the policy effect of government subsidies.When regional integration is at a low level,government subsidies cannot effectively promote enterprises to transfer to the western region.When different enterprises have heterogeneous responses to government subsidies,government subsidies cannot effectively promote high-efficiency enterprises to transfer to the western region first.The empirical study shows that there is a critical value for regional integration to promote the policy effect of government subsidies,and when the level of regional integration is greater than this critical value,government subsidies will play a significant role in enterprise transfer.Only by continuously promoting the development of regional integration and increasing subsidies to enterprises in the western region can we effectively promote the high-quality economic development in the western region.
