Does geographical decentralisation harm the total factor productivity of firms in China?
利用中国工业企业微观数据，研究了城市工业分散化布局对企业全要素生产率的影响，发现分散化在城市化早期和中期会降低生产率，但多中心布局可缓解这种损失。
Under dual market and policy forces, industries vacated central business districts in Chinese cities, showing a decentralised layout. Using Chinese industrial firms’ micro-data (2004–12), with township-level division as the unit, we describe urban industrial decentralisation and polycentric layout, exploring their impact on firms’ total factor productivity (TFP). We found that: (1) industrial decentralisation negatively impacted TFP during the early and middle stages of urbanisation; (2) the polycentric layout can alleviate the firms’ TFP losses caused by decentralisation; and (3) industrial decentralisation reduces diversified agglomeration, lowering TFP. The conclusions of this study provide policy recommendations for urban industrial spatial planning.
