【摘要】：以往的研究使用行业或者地区价格指数平减货币变量时忽视了企业定价异质性,可能导致价格偏误。通过匹配2007-2010年中国海关进出口数据库和工业企业数据库,合并企业财务层面的数据和进出口产品层面的交易信息,计算企业层面的价格指数,以考虑定价异质性。以此重新分析国际贸易与多产品进出口企业生产率的关系,分别考察国际贸易的生产率溢价、自我选择效应和学习效应,结果发现,使用行业价格指数平减低估了国际贸易的生产率溢价;相对于使用行业价格指数平减,使用企业价格指数平减时的出口自我选择效应更明显,但无论采用何种价格指数,进口自我选择效应都不存在;只有在使用企业价格指数平减时,出口学习效应才存在,但使用两种价格指数平减时都存在进口学习效应。
[Abstract]:Previous studies have ignored the heterogeneity of enterprise pricing when using industry or regional price indices to deflate monetary variables, which may lead to price bias. By matching the import and export database of China Customs from 2007 to 2010 and the database of industrial enterprises, combining the financial data of enterprises with the transaction information of import and export products, the price index at the enterprise level is calculated to take into account the heterogeneity of pricing. Based on the analysis of the relationship between international trade and the productivity of multi-product import and export enterprises, the paper examines the productivity premium, self-selection effect and learning effect of international trade. The use of an industry price index deflator understates the productivity premium in international trade; the export self-selection effect of the enterprise price index deflator is more pronounced than that of the industry price index deflator, but whatever price index is used, The import self-selection effect does not exist; only when the enterprise price index is reduced, the export learning effect exists, but the import learning effect exists when the two price indices are deflated.
