技术性贸易壁垒对中国蔬菜出口影响的实证分析

Influence of Technological Barriers to Trade on Chinese Vegetable Export: an Empirical Analysis Based on Gravity Model

技术性贸易壁垒对中国蔬菜出口的影响涉及GDP总额、人口总数、地理距离、汇率、技术性贸易壁垒系数等相关因素.通过构建引力模型研究以上因素可知:贸易国(地区)与我国GDP的上升对我国蔬菜出口存在正向影响,两地直线距离的延长对我国蔬菜的出口有着负面影响,同时技术性贸易壁垒也一定程度地阻碍着我国的蔬菜出口.

A technological barrier to trade （TBT） refers to the compulsory and non-compulsory technological measures imposed by the import countries （areas） when products, services and investments are coming from other countries （areas）. The influence of TBT on Chinese vegetable export involves several factors, such as the total GDP, population, geographic distance, exchange rate, and the coefficient of TBT. By establishing a gravity model of the above-mentioned factors, we can prove that the growth of GDP has a positive influence on Chinese vegetable export while the extension of geographic distance and technolofftcal barrier to trade will negatively affect Chinese vegetable export.
