摘要: 利用WITS关税数据库和BACI微观贸易数据库,基于进口产品质量前沿距离理论模型,在测算中国数字产业出口产品质量升级标准化指数的基础上,研究关税税率政策与进口产品质量前沿距离对出口产品质量的影响机理。通过构建微观层面的系统广义矩估计动态面板数据模型,实证研究发现中国出口产品质量呈上升趋势,其动力源自贸易政策的调整和进口产品质量前沿距离的缩小;关税税率降低对单位产品价值波动有较大影响,进而交叉影响进口产品质量前沿距离,导致出口产品质量升级得以实现。异质性分析表明,高、低质量前沿产品,高、低关税产品和不同数字产业产品的政策效应差别较大。

Abstract: By making use of the WITS tariff database and the BACI micro trade database and applying the theoretical model of import product quality frontier distance, this paper studies the impact mechanism of the tariff rate policy and the import product quality frontier distance on the export product quality based on the calculation of the export product quality upgrading standardization index of China's digital industry. By constructing the dynamic panel data model of systematic generalized moment estimation at the micro level, the results of the empirical study show that the quality of China's export products presents an upward trend, which is driven by the adjustment of the trade policy and the narrowing of the frontier distance of import product quality. The reduction of the tariff rate has a great policy impact on the price fluctuation of unit products, which has a further cross impact on the frontier distance of the imported product quality, resulting in the realization of the upgrading of export product quality. The results of the heterogeneity analysis show that the policy effects of the high-quality and low-quality frontier products, the high-tariff and low-tariff products and the products of different digital industries are quite different.

Key words: trade policy, quality of export products, quality frontier distance, system-GMM estimation
