共同富裕视角下先富地区带动后富地区了吗——基于空间外溢效应的分析

Have the Earlier Prosperous Regions Boosted the Latter Regions under the Perspective of Common Prosperity——Based on Spatial Spillover Effects Analysis

依托先富地区带动后富地区促进区域均衡发展,是扎实推进共同富裕的重要路径。本文利用2010—2020年省际面板数据并采用空间计量模型,从共同富裕视角实证检验先富地区对后富地区的空间外溢效应,发现先富地区通过空间外溢效应带动了后富地区发展。机制分析表明,先富地区对后富地区的空间外溢效应主要表现在经济高质量发展、精神文化繁荣、公共服务均等和生态文明建设四个维度。进一步研究发现,省际对口帮扶样本的空间外溢效应具有统计显著性,主要表现在经济高质量发展和精神文化繁荣两个维度;共同富裕的空间外溢效应会受到地理距离的影响,随着地理距离阈值的提升呈现先增后减的态势,并且当地理距离的阈值超过1 400公里时,先富地区对后富地区的空间外溢效应不再显著。

The earlier prosperous regions boosted the latter regions,which is an important way to promote balanced development among regions and to achieve common prosperity.The article uses the data of the provincial panel from 2010 to 2020 and the spatial model,trying to discuss whether the earlier prosperous regions boosted the latter regions by the spatial spillover effect.According to the inter-provincial common prosperity index,the earlier prosperous regions and latter regions are divided,and the earlier prosperous regions drives the development of the latter regions through the spatial spillover effect.The mechanism analysis shows that the spatial spillover effect of the earlier prosperous regions to the latter rich areas is mainly manifested in four dimensions:high-quality economic development,spiritual-cultural prosperity,equal public service and ecological civilization construction.Further research shows that the spatial spillover effect of provincial counterpart assistance is statistically significant,and the driving effect is mainly manifested in two dimensions:high-quality economic development and spiritual-cultural prosperity.The spatial spillover effect between the earlier prosperous regions and the latter regions is affected by the geographical distance,and the driving effect increases first and then decreases with the limit of 1,400 km.In particular,when the geographical distance exceeds1,400 km,the spatial spillover effect does not show statistical significance.
