Industrial Policy and Competition
利用1998-2007年中国大中型企业数据，发现产业政策若投向竞争性行业或促进竞争，能提升生产率增长；衡量竞争用勒纳指数，政策包括补贴、税收优惠、贷款和关税。
Using a comprehensive dataset of all medium and large enterprises in China between 1998 and 2007, we show that industrial policies allocated to competitive sectors or that foster competition in a sector increase productivity growth. We measure competition using the Lerner Index and include as industrial policies subsidies tax holidays, loans, and tariffs. Measures to foster competition include policies that are more dispersed across firms in a sector or measures that encourage younger and more productive enterprises.
