WHAT MAKES CITIES MORE PRODUCTIVE? EVIDENCE FROM FIVE OECD COUNTRIES ON THE ROLE OF URBAN GOVERNANCE
研究了五个OECD国家中城市治理结构对生产率的影响，发现治理碎片化会降低生产率，而大都市治理机构能缓解这种负面效应，其影响至少与城市规模带来的集聚效益同等重要。
ABSTRACT In estimating agglomeration benefits across five OECD countries, this paper represents the first empirical analysis that contrasts cross‐country evidence on agglomeration benefits with the productivity impact of metropolitan governance structures, while taking into account the potential sorting of individuals across cities. The comparability of results in a multicountry setting is supported through the use of a new internationally harmonised definition of cities based on economic linkages rather than administrative boundaries. The analysis finds that cities with fragmented governance structures tend to have lower levels of productivity. The estimated elasticity for an increase in the number of local jurisdiction is 0.06, which is halved by the existence of a metropolitan governance body. The productivity effect is sizeable and at least as important as the agglomeration benefit found due to city size.
