Abstract: 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 improving 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. The improvement 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.

Key words: input servitization in Manufacturing industry; labor income share; service heterogeneity
