论文摘要

国际关系中的经济不稳定和持续发展需要在区域范围内建立自力更生的贸易和商品流网络,以有效解决一个国家不断增长的人类需求。尽管它在确保印度的粮食安全方面的重要性,但内陆贸易的潜在优势仍未得到探索。在这里,我们对农业流量进行了全面的分析,并将其与印度各州的非农业机构流动进行对比。研究了2010年至2018年期间两个网络的时空演化,并使用网络属性以及总交易价值进行了比较。我们的结果表明,农业和非农业贸易的年度交易销量分别增加了近37%和87%。在两个网络中观察到的总贸易量增加而没有明显的连通性增加,这揭示了过度依赖的依赖性和对特定出口中心的依赖性增加。我们的分析进一步表明,与非农业贸易相比,农业贸易的进出口连接节点之间的分布更加均匀,那里的印度州的出口高进口也很高。总体而言,我们的分析提供了对印度内陆贸易作为一个复杂网络的定量描述,该网络可以进一步设计美国境内的弹性贸易网络。

Rising economic instability and continuous evolution in international relations demand a self-reliant trade and commodity flow networks at regional scales to efficiently address the growing human needs of a nation. Despite its importance in securing India's food security, the potential advantages of inland trade remain unexplored. Here we perform a comprehensive analysis of agricultural flows and contrast it with non-agricultural commodities flow across Indian states. The spatiotemporal evolution of both the networks for the period 2010 to 2018 was studied and compared using network properties along with the total traded value. Our results show an increase in annual traded volume by nearly 37 % and 87 %, respectively, for agriculture and non-agriculture trade. An increase in total trade volume without a significant increase in connectivity over the analyzed time-period is observed in both networks, reveals the over-reliance and increased dependency on particular export hubs. Our analysis further revealed a more homogeneous distribution between import and export connection nodes for agriculture trade compared to non-agriculture trade, where Indian states with high exports also have high imports. Overall our analysis provide a quantitative description of Indian inland trade as a complex network that could further us design resilient trade networks within the nation.
