摘　　要：在中国经济转型和高质量发展的关键时期,通过释放大国空间红利将空间外部性优势转变为经济高质量发展优势具有重要的研究价值。本文利用中国工业企业数据和城市面板数据从要素供给和市场潜力两个方面对空间集聚外部性对城市经济发展质量的影响效应和作用机制进行系统探讨。结果显示,劳动力池、制造业中间品和中间服务空间共享、空间技术外溢等要素供给方面的空间外部性和国内大市场产生的市场需求外部性均有助于引领城市经济高质量发展。进一步研究还表明,国内市场需求的空间外部性与劳动力池效应、制造业中间品空间共享效应、空间技术外溢效应在推进城市经济高质量发展过程中具有协同效应,而国际市场需求外部性则仅与劳动力池效应和空间技术外溢效应存在协同作用。异质性分析表明,劳动力池、制造业中间品和中间服务品空间共享、空间技术外溢效应均显著提高了大城市和中等城市的经济发展质量,而市场潜力扩张则对大城市和小城市的经济发展质量产生了明显的提高作用;城市群政策进一步强化了各类空间外部性优势的充分发挥。In the critical period of China’s economic transformation and high-quality development,it is significant to transform spatial externalities advantages into economic highquality development advantages by releasing the spatial dividend of our big country.This pa-per systematically discusses the effects and mechanisms of spatial agglomeration advantages on economic development quality based on factor supply and market demand.The results show that the spatial externalities of factor supply,such as the labor pool,intermediate input sharing,and technological spillover,as well as spatial externalities of the market demand generated by the expansion of market potential,all contribute to leading the highquality development of the urban economy.Further study also finds that the spatial externalities of domestic market demand have synergistic effects with the labor pool effect,the spatial sharing effect of manufacturing intermediate goods,and the spatial technology spillover effect in promoting high-quality urban economic development.The externalities of international market demand only have synergistic effects with the labor pool effect and spatial technology spillover effect.Heterogeneity analysis found that the labor pool effect,spatial sharing effect of manufacturing intermediate goods and intermediate services,and spatial technology spillover effect significantly improve economic development quality in large and medium-sized cities.Expanding market potential contributes significantly to economic development in large and small cities.The urban cluster policies further strengthened the full exploitation of the advantages of various types of spatial externalities.
