Input-Trade Liberalization,Technology Upgrade and Firms'Output Volatility
In recent years,the international environment has become increasingly complex,and China's foreign trade is facing a marked increase in instability and uncertainty.From the perspective of enterprise out-put fluctuation,based on China Customs data,China industrial enterprise data and HS-6-bit product tariff da-ta,the research studies the impact and mechanism of intermediate goods trade liberalization on the output fluc-tuations of Chinese manufacturing enterprises.The results show that:(1)On the whole,trade liberalization of intermediate goods significantly reduces the output fluctuation of enterprises.(2)Trade liberalization of inter-mediate goods significantly reduces the output fluctuations of export enterprises and domestic enterprises,but has a greater stabilizing effect on the output fluctuations of export enterprises.(3)From the perspective of in-fluence mechanism,trade liberalization of intermediate goods reduces the output fluctuation of enterprises through import diversification effect of intermediate goods and production technology selection effect.For export enterprises,trade liberalization of intermediate goods can also reduce the output fluctuation of enterprises through product quality upgrading effect.(4)The liberalization of trade in intermediate goods has a greater stabilizing effect on the output fluctuations of state-owned enterprises,larger enterprises,and enterprises that import mainly from developing countries.Therefore,we must not only break through key core technologies,enhance the independent and controllable ability of industrial chain and supply chain,but also continue to pro-mote the liberalization reform of intermediate goods trade and make better use of the international market.
