【摘要】While there is considerable empirical evidence on the productivity-enhancing effectsof manufacturing agglomeration, the impacts of knowledge intensive business services (KIBS)agglomeration have rarely been examined. We propose a mechanism-based framework to studythe precise channels through which KIBS agglomeration contributes to urban productivity. Byestimating a model of urban productivity that incorporates agglomeration of manufacturing,KIBS and non-KIB S using city-level data from China, we ?nd that KIBS agglomera tion is animportant source of aggregate urban productivity. The importance of KIBS agglomeration incity productivity growth is systematically related to a city’s level of economic development.
