为何高出口密集度企业的生产率更低?——基于固定成本异质性视角的解释

Why is the Productivity of the Export-Intensive Firms Still Lower? :An Explanation from the Perspective of the Fixed Cost Heterogeneity

为何高出口密集度企业的生产率反而更低?通过将出口密集度和固定成本的取舍关系融入经典异质性企业贸易模型,本文阐述了出口密集度与企业生产率的关联机制。模型结论表明:低效率企业会通过"低固定成本—高出口密集度"方式参与对外贸易,高效率企业则通过"高固定成本—低出口密集度"方式同时在国内和国外市场进行规模化销售。当外需减小时,大规模高出口密集度企业可能首先退出市场。利用中国工业企业层面的微观数据,本文为理论模型提供了稳健的经验证据。

Why is the productivity of the firms with high degree of export concentration(DOEC) is, conversely, still lower?By means of the fusion, of the relationship between the accepting or the rejecting of the DOEC, into the trade model of the classical heterogeneous firms, we have, in this article, elaborated the relative mechanism of the DOEC to firms' productivity. The model shows that the firms with low efficiency will, through the way of'the low fixed cost-the high DOEC', participate in foreign trade, and, however, the firms with high efficiency will, through the way of'the high fixed cost-the low DOEC', sell in large scale in both domestic and foreign markets. When the external demand reduces, the firms with the large scale and with high DOEC will, possibly, firstly withdraw from the market. Using the micro data collected from China's industrial firms, we have, in this paper, provided the experience proofs.
