生产率异质性还是多重异质性——中国出口企业竞争力来源的实证研究

本文分析了Meltiz模型的情境条件，发现生产率异质性是与其三大前提假设紧密相关的。中国情境下，改革开放后不同阶段的不同类型的出口企业：与外商投资相关的企业、生而国际化的企业、先有本土市场而后国际化的企业,它们国际市场竞争力来源不只是生产率异质性，而是存在差异的企业区位、企业年龄、企业规模、创新、品牌、企业性质、企业级别、资本结构、人力资本、成长率等多重异质性。利用中国工业企业数据库，本文实证检验发现，在多个细分行业存在生产率悖论，生产率差异不能有效解释出口企业竞争力，而多重异质性具有更强的解释力，是中国出口企业竞争力来源。

Productivity heterogeneity or multiple heterogeneity: an empirical study on the source of Chinese export enterprise competitiveness

This paper analyzes the conditional situation of the Meltiz model, find that the productivity heterogeneity is its three major premise hypothesis of closely related. In Chinese context, there are different stages of the different types of export enterprises after the reform and opening up: FDI enterprises, born global enterprise, the gradual internationalization enterprises. Their competitiveness in the international market sources not only productivity heterogeneity, but there are differences in the firm location, firm age, firm size, Innovation, brand, the nature of the enterprise, the enterprise level, capital structure, human capital, growth rate of multiple heterogeneity. using China industrial enterprise database, this paper empirically tests found there, productivity paradox in a plurality of sub sectors, productivity differences cannot explain the export competitiveness of enterprises, and the multiple heterogeneity has stronger explanatory power, is the source of Chinese competitiveness of export enterprise.
