异质性企业、技术进步与比较优势——对微观企业贸易数据的经验分析

摘要笔者以1998年～2008年的中国微观企业出口贸易数据为基础, 实证检验了企业异质性、技术进步对出口贸易比较优势的影响。研究结论表明, 在控制了经济规模、贸易成本、汇率、行业产出、区域和所有制差异等变量后, 偏向性技术进步比中性技术进步更适合解释中国异质性企业的出口差异问题, 且偏向资本的技术进步是我国劳动密集型企业出口比重下降而资本技术密集型企业出口比重上升的重要原因。进一步使用偏向性技术进步实证检验中国出口贸易的比较优势后, 偏向资本的技术进步有助于防范中国出口贸易陷入“比较优势陷阱”, 实现出口贸易的动态比较优势升级。

Abstract： Given the micro-firms’ trade data of China from 1998 to 2008, the paper empirically analyzes the effects between heterogeneous firms, technical progress and comparative advantages. The results show that the biased capital technical progress is more suitable to explain the differences between Chinese heterogeneous firms’ exporting, and capital biased technical progress is the main reason to decrease the export of labor-intensive firms but increase the capital-intensive enterprises, even controlling the variables of economic scale, trade costs, exchanging rate, industrial output, regional and ownership difference. Moreover, the biased capital technical progress can prevent China to fall into the traps of comparative advantage, and realize the dynamic comparative advantage for exporting.

Keywords： Heterogeneous Firms Neutral Technology Progress Biased Technology Progress Comparative Advantage
