【摘要】 与传统城镇化截然不同，中国正在经历的新型城镇化发展更强调通过城乡要素融合促进经济增长和城乡收入差距缩小，实现共同富裕。尽管国家新型城镇化综合试点政策是推进新型城镇化建设的重点策略，但关于其促进共同富裕的实证研究仍然不足。因此，本文以国家新型城镇化综合试点政策为准自然实验，收集2000—2022年中国1980个县(区、市)面板数据，运用多期双重差分模型分析该政策的共同富裕效应并揭示其影响机制。研究结论显示：该政策不仅促进了经济增长，还显著减少了城乡间的收入差距，这一效应随着政策实施时间的延长而增强；此政策效果在西部地区最为显著，其次是中部地区，而在东部地区则不明显；此外，与原非贫困县相比，原贫困县的受益更加显著；政策通过劳动力转移和资金及信息的融通等途径发挥作用。基于此，本文提出在持续释放试点政策共同富裕效应的基础上，完善劳动、资本、数据信息等生产要素城乡融合机制，并建议政策设计更加注重因地制宜的差异化策略。更多还原

【Abstract】 Unlike traditional urbanization, new urbanization that China is experiencing puts more emphasis on promoting economic growth and narrowing the urban-rural income gap through the integration of urban and rural resources to achieve common prosperity.Although the national comprehensive pilot policy of new urbanization is the key strategy to promote the construction of new urbarization, empirical studies on its role in promoting common prosperity remain limited.Therefore, this study treats the national comprehensive pilot policy of new urbanization as a quasi-natural experiment, using a panel data from 1980 counties(districts and cities)in China spanning 2000-2022.It employs a multi-period difference-in-differences model to evaluate the policy’s impact on common prosperity and uncover its underlying mechanisms.The findings show that the national comprehensive pilot policy of new urbanization not only promotes economic growth but also significantly reduces the urban-rural income gap, with its effect strengthening over time.The impact is most pronounced in the western region, followed by the central region, and is least significant in the eastern region.Additionally, formerly impoverished counties benefit more than non-impoverished ones.The policy’s impact operates through channels such as labor transfer and the integration of capital and information.Building on the ongoing realization of the common prosperity effects of pilot policies, this paper recommends improving the integration mechanisms for production factors like labor, capital, and data between urban and rural areas.It further suggests that policy design should prioritize differentiated strategies adapted to local conditions.更多还原
