This study investigates the influence of urban agglomeration policy on innovation efficiency through a difference-indifferences analysis. Findings reveal that urban agglomeration policy has led to a decrease of 3.65% in the innovation efficiency of urban agglomerations, although there is heterogeneity in the policy's impact across these agglomerations. Cities within agglomerations are categorised into core and non-core cities, while the policy has boosted innovation efficiency by 10.1% in core cities but by −3.89% in non-core cities. Overall, urban agglomeration policies exhibit a more pronounced innovation siphoning effect, and mechanism testing of labour and commodity markets corroborates this observation.

Regional Studies

Regional Studies is a leading international journal covering the development of theories and concepts, empirical analysis and policy debate in the field of regional studies. The journal publishes original research spanning the economic, social, political and environmental dimensions of urban and regional (subnational) change. The distinctive purpose of Regional Studies is to connect insights across intellectual disciplines in a systematic and grounded way to understand how and why regions and cities evolve. It publishes research that distils how economic and political processes and outcomes are contingent upon regional and local circumstances. The journal is a pluralist forum, which showcases diverse perspectives and analytical techniques.    Essential criteria for papers to be accepted for Regional Studies are that they make a substantive contribution to scholarly debates, are sub-national in focus, conceptually well-informed, empirically grounded and methodologically sound. Submissions are also expected to engage with wider debates that advance the field of regional studies and are of interest to readers of the journal.

The journal publishes original research that spans the economic, social, political, and environmental dimensions of urban and regional (subnational) change. Its distinctive purpose is to systematically and rigorously connect insights across various intellectual disciplines to understand how and why regions and cities evolve. The research published distills how economic and political processes and outcomes are contingent upon regional and local circumstances. The journal serves as a pluralistic forum that showcases diverse perspectives and analytical techniques. Essential criteria for papers to be accepted in Regional Studies include making a substantive contribution to scholarly debates, focusing on sub-national issues, being conceptually informed, empirically grounded, and methodologically sound.
