Affecting Factors and Quantile Heterogeneity on the Agglomeration of Specialized and Sophisticated"Little Giant"Firms:An Empirical Study Based on Quantile Regression Models
The specialized and sophisticated"Little Giant"firms play an increasingly important role in promoting the transformation,upgrading and strengthening of supply chains for Chinese SMEs.This article takes the five batches of specialized and sophisticated"Little Giant"firms recently recognized by the Ministry of Industry and Information Technology as research objects.It analyzes the regional and industrial distribution characteristics,and uses the quantile regression model to study the affecting factors of enterprise agglomeration and the heterogeneity of their effects at different agglomeration levels.The results show that:1)The regional distribution of"Little Giant"firms in different batches has distinct policy orientations,with a clear dominance in eastern regions overall,highly concentrates in central cities of the five major urban agglomerations.In terms of industry distribution,manufacturing industry accounts for more than half but with a slight decrease over time,while productive service industries show a steady increase proportionally.2)Industrial foundation,economic environment,business environment,policy environment,etc,collectively affect the level of"Little Giant"firms agglomeration.Moreover these factors have obvious heterogeneity in their effects on different percentile levels of agglomeration.3)Industrial foundation and policy environment only significantly promote low-level agglomerations among"Little Giant"firms.The economic development level has no significant effect on the improvement of the agglomeration degree of"Little Giant"firms(there is no"bigger one takes all"phenomenon).Human capital level has a significant effect on the improvement of the agglomeration degree of"Little Giant"firms.Business environment only significantly promotes the high-level agglomeration degree of"Little Giant"firms,the influences of human capital level and business environment both increase as aggregation increases.
