摘　　要：在将SITC贸易部门分类与工业分类体系匹配的基础上,本文利用1998~2012年的跨国行业面板数据,通过固定效应和系统GMM方法,实证检验了全球及分国别的制造业行业进口对我国劳动收入占比的影响,并通过引入行业交互项,细致对比了进口对不同行业的影响差异。研究发现,进口贸易对劳动收入占比呈现出显著的负效应,即进口贸易扩张降低了劳动收入占比,且这种影响在不同国家间呈现明显差异,西欧和美国的负效应最为明显,而东盟和金砖国家的影响次之,日韩两国的影响则最小。区分劳动密集型行业和资本技术密集型行业的研究也证实,进口贸易对资本技术密集型行业劳动收入占比的降低作用大于劳动密集型行业,扩大了劳动收入占比的行业差异,且来自西欧4国和美国进口的影响同样大于东盟、金砖国家和日韩两国。By matching the SITC trade sector classification and industrial classification systems, the paper analyzes empirically the impact of the global and sub-country imports on China＇s labor income share using the cross-country industrial level panel data during the period 1998 - 2012. This paper also compares the difference of effects of imports on various industries through the fixed effects, system GMM and the interaction term method. The estimation results show that the import trade presents a significantly negative effect on the labor income share; in other words, the import trade reduces the labor income share. This effect shows significant differences between different countries, with the negative effect in Western Europe and the United States the most obvious, the impact in ASEAN and BRICS taking the second place, and the negative influences in Japan and South Korea the minimal. Research distinguishing the labor-intensive industries and capital and technology-intensive industries also confirms that import trade plays a more significant role in reducing the labor income share in the latter than in the former, which expands the industry differences in labor income share. This effect in Western Europe and the United States is also greater than that in ASEAN, BRICS and South Korea.
