目的国市场对出口企业产品质量升级的影响

摘要

本文通过理论模型分析出口目的国市场消费者偏好对企业最终产品与中间投入品质量的影响。在此基础上，利用中国企业的微观数据，同时控制出口成本、企业规模与企业出口密集度等变量，验证理论模型的结论。结果表明，企业最终产品质量会随着出口目的国市场收入水平的增加而显著提高，部分原因可能来自于中间投入品的质量升级。最后，分别采用海关数据与世界银行数据构建相关替代指标与目的国收入水平的工具变量，在控制内生性问题的情形下，进一步考察目的国市场对于出口企业产品升级的直接与间接影响，以验证模型的稳健性。%This article analyzes the impact of consumer preferences in export destination on quality of enterprises’ final goods and intermediate inputs.Chinese enterprises’micro data are used to verify the theoretical model’s analysis by controlling trade costs of enterprises,enterprise scales and export intensive.The results show that the final products’ quality will increase when the income level of the countries exported improves,and it is partly because of inputs’quality upgrade.Besides,data of customs and the World Bank are used to construct alternative quality index and instrumental variables of destination countries’income,verifying the robustness of the index and the model.
