贸易壁垒的降低和经济一体化的深化推动了全球贸易尤其是产业内贸易的发展,而贸易发展与其引致的要素市场调整之间的相互关系成为各方研究的焦点之一。本文选取2000-2007年中国制造业27个细分行业作为研究对象,运用广义矩估计等计量方法对“平滑调整假说”进行实证研究,结果一致证实了“平滑调整假说”在中国的有效性,即中国产业内贸易水平的提高降低了劳动力等要素市场的调整成本。回归结果还表明,显性需求和外资企业就业比重是中国就业变化的主要影响因素,对外开放程度的影响同样不可忽视。最后,本文在研究结论基础上提出了扩大内需、鼓励外商投资等建议,并指出了未来研究方向。

The results consistently confirm that the “smooth adjustment hypothesis” in China The effectiveness of China's intra-industry trade has lowered the adjustment costs of labor and other factor markets.
