制造业投入服务化是否改善劳动收入份额——基于中国制造业企业数据的经验分析

Does Input Servitization in Manufacturing Industry Improve Labor Income Share? Empirical Analysis Based on the Data of Chinese Manufacturing Enterprises

运用投入产出表和中国工业企业数据等合并数据,从城市和企业层面探讨制造业投入服务化对劳动收入份额的影响。实证结果显示:制造业投入服务化显著提高了劳动收入份额。从服务投入异质性的视角来看,相对于生产性服务投入,生活性服务投入的劳动收入份额提高作用更大;分销服务投入的劳动收入份额提高作用同样显著,金融服务投入的劳动收入份额提高效应不显著,而电信服务投入和运输服务投入降低了劳动收入份额。制造业投入服务化程度的提高,通过增加企业竞争力、增强专业化分工水平和降低生产成本引起企业劳动收入份额的提高,但制造业投入服务化引致的人力资本的增长会引起企业劳动收入份额的降低。

This paper uses the input-output tables and Chinese industrial enterprise data to probe into the impact of the input servitization in manufacturing industry on labor income share from the city and enterprises level.The empirical results show that input servitization in manufacturing industry has significantly raised labor income share.From the perspective of service input heterogeneity,compared with productive services input,the labor income share of life services input have a better im-proving effect.The distribution services input has the same significant impact on the improvement of labor income share,while the effect of financial services input proves insignificant,but the telecommunication services input and the transport services input have reduced the labor income shares.Theimprovement of service input in the manufacturing industry can lead to the improvement of enterprises labor income shares through increasing corporate competitiveness,enhancing the specialization level and reducing production costs.But the increase of human capital caused by servitization input in manufacturing industry will give rise to the decrease of enterprise labor income shares.
