Through the analysis of statistical data, some scholars believe that the globalization of trade is declining, and de-globalization has become a trend, even since the financial crisis in 2008. However, the superficial decline of global trade volume cannot be taken as a corollary of the de-globalization. It needs go deep into the structural analysis, and “globalization or de-globalization” should be discussed by analyzing whether the global trade structure has changed. This paper finds that during 2007–2017, the global trade resistances are clearly classified, and trade resistance in the global community has increased significantly. Second, an expectation maximization (EM) algorithm is applied to divide global trade relations into two categories: intimate trade relations, whose barriers are mainly related to geographical distance; and unfriendly trade relations with high artificial barriers. Third, the trade purity indicator (TPI) is introduced to describe the trade environment of countries, and its evolution indicates after the financial crisis and for quite a long time, the structure of global trade has not changed much. And it shows some deterioration trend and structural adjustment after 2015, which indicates an opportunity for the emergence of de-globalization in such an international environment full of uncertainty and challenges.

是我们在去全球化进程？从全球贸易中的体现2007 - 2017年期间

通过统计数据分析，有学者认为，贸易的全球化正在下降，和去全球化已经成为一种趋势，甚至自2008年金融危机。然而，全球贸易额的肤浅的下降不能被视为一个必然结果的去全球化。它需要深入到结构分析，以及“全球化和去全球化”应该通过分析全球贸易结构是否发生变化进行讨论。本文发现在2007至2017年，全球贸易电阻明确分类，贸易性的全球社会显著上升。其次，期望最大化（EM）算法应用到全球贸易关系分为两类：亲密的贸易关系，其障碍主要涉及到的地理距离; 高人为障碍和不友好的贸易关系。第三，贸易纯度指示器（TPI）引入来形容国家的贸易环境，以及金融危机后的发展表示和相当长的一段时间，全球贸易的结构没有太大的变化。它表明2015年后一些恶化的趋势和结构调整，这表明去全球化的在这样的国际环境充满了不确定性和挑战的出现提供了机会。
