浙江省行业间收入差距的变动特征及决定因素——基于制造业经济普查数据的实证研究

Characteristics of Changes and Determinants of the Income Gap between the Industries in Zhejiang Province——Empirical Research of the Economic Census Data of Manufacturing

文章根据2004年第一次、2008年第二次经济普查数据，对浙江省行业间收入差距的变动特征及决定因素进行了深入分析，得到以下结论：福利费支出扩大了行业间收入差距。在工资性收入的基础上考虑福利费之后行业收入差距的基尼系数会上升3％-7％；浙江省制造业行业问收入差距在下降，2008年与2004年相比，行业间收入差距的基尼系数下降了13％-15％；影响行业平均收入的行业特征变量按其重要性排序依次为行业盈利能力、行业资本密度、行业垄断、行业技术效率。2008年与2004年相比，行业盈利能力影响程度在加强，行业资本密度、行业垄断等行业特征变量的影响程度在减弱，表明浙江省劳动力市场一体化程度在加强。行业间收入差距在向更为合理的方向发展。

This paper made a depth analysis of the characteristics of changes and determinants of the income gap between the industries in Zhejiang Province based on the first and second economic census data in 2004 and 2008. The result show that, firstly, welfare spending expanded the income gap between the industries. The Gini coefficient of industries income gap would rise 3% to 7% after considering welfare on the basis of wage income. Secondly, the income gap between the Zhejiang manufac- turing was declining. Compared 2008 with 2004, the Gini coefficient of industries income gap has dropped by 13%-15%. Thirdly, industry characteristic variables which affected the industry average income are sorted to profitability of the industry, capital intensity of the industry, industry monopoly, and technical efficiency of the industry according to their importance. Compared 2008 with 2004, the influence of the industry profitability was strengthening, the influence of other variables was declining. The findings above show that the level of Zhejiang labor market integration was strengthening, and income gap be- tween the industries was developing to a more reasonable direction.
