中等收入阶段产业结构变动对劳动收入份额的影响研究

Impacts of Industrial Structure Change on Labor Income Share in Middle-income Stage

以中等收入阶段为时间背景,利用我国1998-2017年29个省份的面板数据,实证研究产业结构变动对劳动收入份额的影响及区域异质性,并运用系统GMM两步法对模型进行稳健性检验。结果显示:产业结构变动对劳动收入份额存在显著的正向影响,东部地区产业结构变动对劳动收入份额的影响程度大于中部和西部地区;第一产业与第三产业占比的提升对劳动收入份额有显著促进作用,第二产业占比对劳动收入份额存在显著负向影响且影响程度在三次产业中最大。总体来说,为提高劳动收入份额,应促进第三产业占比的提高,保证第一产业与技术的结合发展,加速劳动力结构转型;同时,也要考虑我国经济发展水平的实际和不同地区存在的差异,提升资源与各要素的使用效率。

Taking middle-income stage as the time background,the panel data of 29 provincial administrative units in China from 1998 to 2017 is used to empirically study the impacts of industrial structure change on labor income share and regional heterogeneity,and the systematic GMM two-step method is used to test the robustness of the model. The results show that industrial structure change has a significant positive impact on the share of labor income,and the influencing degree in eastern area is larger than that in middle and western areas;the increase of the proportion of the primary industry and the tertiary industry has a significant promoting effect on the share of labor income,while the proportion of the secondary industry has a significant negative effect on the share of labor income,and the influencing degree is the largest among the three industries. In general,in order to increase the share of labor income,the increase of the proportion of tertiary industry should be promoted,the combination of primary industry and technology should be ensured,and the transformation of labor structure should be accelerated. At the same time,the actual level of China’s economic development and the differences among different regions should also be considered to improve the efficiency of the use of resources and various elements.
