针对国内以往检验“出口学习”效应的文献在方法上存在的一些问题,本文将出口行为引入企业生产率动态轨迹中,在估计生产函数时,考虑了出口内生性问题,以更稳健的方法检验了“出口学习”假说在中国情境下的适用性。通过对1998-2007年企业样本的研究发现:(1)在总体水平上,存在一定程度的出口学习效应,一年的出口经历可使企业生产率提升约2.2%;(2)出口学习效应不仅在不同行业中存在较大差异,其大小也随企业出口密集度的上升呈倒U形变化;(3)出口企业的集聚在提升企业生产率的同时,也在一定程度上促进了出口学习;(4)研发支出提高了出口企业的生产率,但对出口学习效应的影响不显著。
Aiming at some problems existing in the literature of domestic test “export learning ” effect, this paper introduces the export behavior into the dynamic trajectory of enterprise productivity. When estimating the production function, we consider the export endogeneity problem and adopt a more robust method Test the applicability of the “exit learning” hypothesis in China. Through the study of the corporate samples from 1998 to 2007, we find: (1) At the overall level, there is a certain degree of export learning effect, and one year’s export experience can increase enterprise productivity by about 2.2%; (2) (3) The agglomeration of exporting enterprises promotes the export-oriented learning to a certain extent while promoting the productivity of enterprises (4) R & D spending has increased the productivity of exporting enterprises, but the effect on export learning has not been significant.
