Entropy and scaling behaviors of international trade patterns

초록

We investigate the impact of international commodities trade on economic growth of five Asian countries including China over the last two decades. We examine the exports of eight commodity categories from 1995 to 2018. Firstly, we calculate trade entropy by considering the probability of exporting a product from one country to another. Our analysis reveals a significant increase in China's trade entropy for manufactured goods primarily classified by material, compared to other products. The strong correlation between changes in gross domestic product (GDP) and trade volume in China indicates a remarkable contribution of manufactured goods to GDP during the studied period. Additionally, we establish a power law-scaling relation between GDP and product exports over time. Notably, the growth of manufactured goods from China exhibits a super-linear relationship with GDP.
