城镇化、经济集聚与区域经济增长异质性——基于空间面板杜宾模型的经验证据

Urbanization, Economic Agglomeration and Heterogeneity of Regional Economic Growth——Empirical Evidence Based on Spatial Panel Durbin Model

前沿研究大多关注城镇化对经济增长的影响,却普遍忽视城镇化是否会通过区域经济空间关联影响经济增长。在结合区域经济空间异质性事实的基础上,通过运用空间面板杜宾模型检验城镇化的空间经济增长效应,结果发现:中国区域间城镇化的经济增长效应显著且空间异质性突出,经济集聚在其中扮演重要角色。正是地区集聚能力差异引发城镇化的经济增长异质性后果,西部地区更易通过资源集聚和消费提升扩大城镇化影响,集聚能力甚至显著抑制东中部地区城镇化的经济增长效应。分类检验结果发现,东中西部经济增长动力存在明显差异。

Frontier research pay more attention to the role of urbanization in regional economic growth,but generally ignores the spatial correlation between regions, and does not provide empirical evidence for exploring the story behind the economic growth induced by urbanization. Based on the spatial heterogeneity between regions, this paper uses the spatial panel durbin model to measure the effect of urbanization spatial economic growth and its underlying mechanism, and to explore the causes of urbanization differences in different regions.The results show that the economic growth effect of inter-regional urbanization in China is significant, and it strongly promotes regional economic growth. However, according to the test results of different regions, the economic growth effect of urbanization level has spatial heterogeneity. In the process of urbanization’s positive effect on economic growth, economic agglomeration plays an important role. The difference of regional agglomeration ability leads to the heterogeneous consequences of regional economic growth. We find that the western region is more likely to expand the role of urbanization in promoting economic growth through resource agglomeration and consumption promotion, while the regional consumption capacity has not shown a significant effect in the eastern and central regions, and agglomeration capacity has even significantly inhibited the economic growth of urbanization in the eastern and central regions. The development of the eastern region depends more on the upgrading of industrial structure and investment, while the investment in the western region has reversely inhibited the economic growth effect of urbanization.
