贸易自由化与中国劳动需求弹性:基于制造业企业数据的实证分析

Trade Liberalization and Labor Demand Elasticity:Firm-level Evidence from China's Manufacturing Sectors

本文采用中国制造业企业1998-2007年的微观面板数据,研究贸易自由化对企业劳动需求弹性的影响。我们将中国加入世界贸易组织视为一次自然实验,以加工进口企业为"控制组",以一般进口企业为"处理组",采用倍差法和固定效应模型进行回归分析。结果显示,贸易自由化通过提高资本品和中间产品的可获得性,显著提高了劳动需求弹性。进口关税下降越多,企业的劳动需求弹性提高也越多。

Using 1998 - 2007 firm - level panel data of manufacturing finns, this paper investigates the effects of China＇s trade liberalization on labor demand elasticity. We take China＇s WTO accession as a natural experiment and regard processing import In-ms as ＂control group＂ and ordinary import fh-ms as ＂treatment group＂ . After implementing difference -in -difference and fixed -effect methods, we find trade liberalization increases labor demand elasticity by improving availabilities of capital goods and intermediate goods. The more reductions in import tariffs, the more increases in labor demand elasticity on firm level.
