长三角地区劳动收入份额下降的决定因素研究

Study on the Determinants of Labor Income Share Decline in Yangtze River Delta Region

长三角地区劳动收入份额呈逐渐下降趋势,由2001年的66.5%下降到2009年的56.6%,下降了近10个百分点。劳动收入份额的下降与经济的快速发展形成鲜明的对比。实证研究表明:长三角地区资本和劳动呈现出互相替代的关系,引进外资、发展对外贸易等全球化的经济活动并没有显著地导致劳动收入份额的下降。转型因素对劳动收入份额的影响作用显著,国民经济中劳动收入份额相对较低的第二产业和第三产业的比重上升以及地方政府绩效竞争降低了劳动收入份额,而城镇化则促进了劳动收入份额的上升。

The share of labor income in Yangtze River Delta experienced a gradual decrease from 66.5% in 2001 down to 56.6% in 2009,dropped by nearly 10 percentage points.The decline of labor income share is in sharp contrast to the rapid development of economy.Empirical study show that capital investment and labor input of the region have the relationship of replacing each other,and the activities of globalization such as introduction of foreign investment and development of foreign trade do not significantly lead to labor income share decline.Transformation factors have significant influence on labor income share.The rising proportion of secondary and tertiary industry in national economy and the performance competition of local governments lead to the decrease of labor income share,while urbanization increases labor income share on the other hand.
