Industry Chain Leading Firms,Super Large-scale Market and Manufacturing Labor Productivity
Industrial chain leading firms are key players in the super large-scale market to promote the high-quality development of the manufacturing industry.In the context of accelerating the construction of a unified national market in China,exploring the impact of industry chain leading firms on manufacturing labor productivity holds significant practical significance for unleashing the dividend of the industry chain in China's super large-scale market and promoting the high-quality development of manufacturing.This paper is to investigate the effects of industry chain leading firms on manufacturing labor productivity and the moderating effect of China's super large-scale market.In this paper,the top 100 firms in the total output value of each manufacturing two-digit industry are defined as leading firms,and the input-output coefficients are used to characterize the industrial chain association,based on which the index of industry chain leading firms is calculated.The empirical analysis in this paper uses the matching data of Chinese cities and industrial firms within the framework of agglomeration economics.The main data sources are the input-output table data published by the National Bureau of Statistics of China,and the China Industrial Enterprises Database.This paper finds that the industry chain leading firms significantly improve manufacturing labor productivity,and China's super large-scale market significantly strengthens the positive effects of industry chain leading firms on labor productivity.Based on the baseline regressions,the paper conducts robustness tests in terms of replacing the core variables,excluding alternative explanations,considering the spatial scope of the role of leading firms,and using transportation infrastructure to characterize the super large-scale market.We test the mechanisms by deconstructing the agglomeration externality of industry chain leading firms,and find that the labor pool,intermediate inputs sharing,and technology spillover effects related to industry chain leading firms are important mechanisms.Further analysis indicates that in improving manufacturing labor productivity,China's super large-scale market has a synergistic effect with the intermediate inputs sharing and the technology spillover of industry chain leading firms,but has a substitution effect with the labor pool of industry chain leading firms.Heterogeneity analysis shows that the super large-scale market reinforces the labor productivity-enhancing effect of industry chain leading firms on industries with a high degree of competition and larger firms.The policy implications lie in leveraging the advantages of super large-scale market and industry chain leading firms and thus promoting the high-quality of manufacturing.The findings of this paper provide useful theoretical guidance for the formulation of related policies.On one hand,we should give full play to the industry chain leading firms,so that they can drive more firms to improve labor productivity through various ways.By giving full play to the ecological dominance of industry chain leading firms,China's economy can realize effective qualitative improvement and reasonable quantitative growth.On the other hand,in building a new development pattern,it is necessary to unswervingly promote the construction of a unified national market.The government should continuously promote the advantages of the super large-scale market to empower industry chain leading firms,so that the super large-scale market can become an important engine for the high-quality development of manufacturing.The main innovations of this paper lie in two aspects.Firstly,this paper reveals the mechanism by which industry chain leading firms affect manufacturing labor productivity from the perspective of the externalities of large firms'agglomeration and confirms the synergistic effect between industry chain leading firms and the super large-scale market.This helps deepen the understanding of industry chain leading firms promoting high-quality development of manufacturing.Secondly,the paper optimizes the design of the index of industry chain leading firms,providing a more reasonable index for subsequent related research.
