出口质量提升如何影响了企业产出波动——基于出口强度的视角

How the Improvement of Export Quality Affect Enterprise’ Output Volatility:From the Prospective of Export Intensity

从出口强度的视角考察出口质量提升影响企业产出波动的理论机制,并利用2000-201 3年中国海关数据库和工业企业数据库进行实证检验。研究发现:将企业总产出波动分解为出口波动和国内波动,出口质量提升通过出口强度的增加减少了出口波动,加剧了国内波动;对于总产出波动,出口强度有门槛效应,当出口强度小于0.411时,出口质量提升能够减少总产出波动;出口质量的集约边际减少了出口波动,出口质量的拓展边际加剧了出口波动和总产出波动。

This paper examines the theoretic al mechanism of the improvement of export quality affecting enterprises’ output volatility from the perspective of the export intensity, and then it conducts an empirical test based on the China customs database and the industrial enterprise database from 2000 to 2013. The findings show that when the enterprise gross output volatility is decomposed into the export volatility and domestic volatility, the improvement of export quality will reduce the export volatility through the increase of export intensity and intensify the domestic volatility. As for the total output volatility, there is a threshold effect on the export intensity: when the export intensity is smaller than 0.411, the improvement of export quality can reduce the total output volatility. The intensive margin of the export quality can reduce the export volatility, and the expansion margin of the export quality can intensify the export volatility and the total output volatility.
