生产率对企业出口的影响研究——兼论新新贸易理论在中国的适用性

随着新新贸易理论的建立与不断发展,基于生产率异质性研究企业出口越来越受到重视。本文首先提出数理模型来分析生产率对出口的决定机制,再通过2007年中国制造业企业样本检验企业生产率对其出口决策以及出口规模的影响。结论认为:生产率的提高会使企业更具有能力选择出口,但是在自由决定进入国内市场以及出口市场时,企业未必会因为生产率的提高而选择出口;对于全体样本,实证检验认为生产率与企业出口行为是负相关的,对于出口企业样本,实证检验也认为企业生产率与其出口规模是负相关的。这样可以看出,新新贸易理论在中国的适用性还需更进一步研究。

The Study of the Influence of the Productivity to Export:The Applicability of New-New Trade Theory in China

With the establishment and the development of new new trade theory,the increasing attention is payed to export based on the heterogeneity of productivity.This paper proposes a mathematical model to analyze the decision-making mechanism of the influence of the productivity on export.Then it inspects the impact of productivity of the decision-making on export and its export scale through the sample of Chinese manufacturing enterprises in 2007.The paper concludes that the increase of productivity will make the enterprise more ability to choose export.But when it comes to a free decision to enter the domestic market or export market,the enterprise may not necessarily choose export because of its higher productivity.For the entire samples,empirical test show a negative correlation between the productivity and export behavior.In addition to this,empirical tests also consider that the productivity is negatively correlated with the export scale.This can be seen the applicability of new new trade theory in China needs further study.
