我国农产品出口对氮肥使用的影响

摘要

At present, China′s agricultural products scale of export expands and brings more agricultural non-point source pollution.As the main source of pollution, Nitrogen directly affects the situation of agricultural non-point source pollution.Using 2000-2013 panel data of 31 provinces (municipalities and autonomous regions), this paper groups ac-cording to the level of agricultural production and the scale of export, and analyzes the influence of agricultural products export trade on the amount of nitrogen fertilizer used in agricultural non-point source pollution and regional differences, finding that low agricultural production regions and high export regions are using less nitrogen fertilizer.%目前，我国农产品出口规模日益扩大，农业面源污染问题也日益严重，以氮肥为主要的污染源直接影响农业面源污染状况。本文选取2000－2013年31个省、直辖市和自治区的数据，根据农业生产水平和出口贸易水平分组，分析农产品出口贸易对农业面源污染中氮肥使用量的影响及区域的差异，发现我国低农业生产地区和高出口贸易地区氮肥使用的改善程度明显。
