    摘要:

    基于2003—2018年中国26个省份的面板数据,采用超效率SBM模型测算广义农业绿色全要素生产率,探究农产品国际贸易水平对农业绿色全要素生产率的影响。研究结果表明,农产品国际贸易水平对农业绿色全要素生产率存在促进作用,同时滞后性明显,估计结果稳健;农产品出口贸易水平和农产品进口贸易水平对农业绿色全要生产率均呈正向显著影响,且出口的影响系数小于进口的影响系数;南方和北方省份农产品国际贸易水平对农业绿色全要素生产率均存在正向影响,且北方省份农产品国际贸易水平回归系数高于南方省份;为考察不同层次的农产品国际贸易水平的影响进行分位数回归,随着农产品国际贸易水平的增加,农产品国际贸易水平的促进作用逐渐不显著。

    Abstract:

    Based on the panel data of 26 Chinese provinces from 2003 to 2018,the super efficiency SBM model was adopted to measure the generalized agricultural green total factor productivity, and it is explored the impact of the international trade level of agricultural products on the agricultural green whole factor productivity. The results show that, the international trade level of agricultural products promotes the agricultural green total factor productivity,and estimated results are robust.The level of agricultural export trade and the import trade level of agricultural products have a positive and significant impact on the productivity of agricultural green, the influence coefficient of export is less than that of import.The international trade level of agricultural products in southern and northern provinces has a positive impact on agricultural green total factor productivity, and the return coefficient of the international trade level of agricultural products in northern provinces is higher than that of southern provinces. It is conducted the quantile regression for examining the impact of international trade levels of agricultural products at different levels.As international trade in agricultural products increases, the promotion role of the international trade level of agricultural products is gradually not significant.
