中国企业出口频率:事实与解释

Firm's Export Frequency in China: Facts and Explanations

本文采用2000-2006年中国工业企业数据库与中国海关数据库的匹配数据运用计数模型考察了出口频率的影响因素。研究结果发现,样本期企业出口频率普遍较低,中位出口频率为1次,平均出口频率为2.49次;企业、出口产品及目的国特征因素对出口频率都具有显著影响,尤其体现在出口产品特征上。企业出口规模、目的国不确定性以及出口产品多样化、出口产品核心程度增加均能显著提高企业出口频率。此外,本文还基于中国加入WTO对不同贸易方式出口的作用差异证实了出口频率能够作为出口增长边际的事实。

We adopt a count model with matching data of Chinese firm-level data and export data over the period 2000-2006 to study the determinants of export frequency. The results reveal that export frequency is generally low, the median frequency is one time and average frequency is 2.49 times ; the characteristics of firms, export products and destinations have significant effects on export frequency, especially for the export products characteristics. Firms＇ export scale, uncertainty of the destinations, diversification and the core degree of export products all have positive significant effects on export frequency ; Furthermore, different effects of China＇s accession to the WTO on general trade and processing trade confirm the fact that export frequency should be considered as an export margin.
