摘要
依据理论机制与模型论证基础设施和共同富裕的关系,并基于2010—2020年全国208个主要地级市数据,实证检验交通、教育基础设施改善对共同富裕的作用、路径及异质性效果。研究表明:交通和教育基础设施改善能显著促进共同富裕,但存在区域城市异质性效果和时滞效应。交通基础设施改善能通过推进人口城镇化、促进就业、强化经济集聚能力建立促进共同富裕的长效机制,而教育基础设施在通过改善人口城镇化助力共同富裕方面存在一定的阻碍。在农村收入占比的双重门槛约束下,两种基础设施的共同富裕效应存在差异:当农村收入占比处于低门槛区间时,教育基础设施的共同富裕效应显著,但交通基础设施效果失灵;随着农村收入占比的增长,交通基础设施的挤占效应消失;当农村收入占比处于高门槛区间,教育基础设施作用不显著,交通基础设施的边际贡献显著为正。
Based on theoretical mechanisms and models to demonstrate the relationship between infrastructure and common prosperity,and on the data of 208 major prefecture-level cities in China from 2010 to 2020,we empirically test the role,paths and heterogeneous effects of transportation and education infrastructure improvement on common prosperity.The study shows that transportation and education infrastructure improvements can significantly promote common prosperity,but there are regional urban heterogeneity effects and time lag effects.Transportation infrastructure improvement can establish a long-term mechanism to promote common prosperity by promoting population urbanization,boosting employment,and strengthening economic agglomeration capacity,while there are obstacles to the mechanism of education infrastructure to promote common prosperity by improving population urbanization.Under the double threshold constraint of rural income share,the common prosperity effect of the two infrastructures differs.When the rural income share is in the low threshold range,the common prosperity effect of education infrastructure is significant,but the effect of transportation infrastructure fails;as the rural income share grows,the crowding-out effect of transportation infrastructure disappears;when the rural income share is in the high threshold range,the effect of education infrastructure is not significant,the marginal contribution of transportation infrastructure is positive.
