为了研究贸易成本降低的效果，我们开发了一个模型，从商品和产业两个方面来重构国际贸易网络。首先，我们估算了复制WIOD和NBERUN数据的交易成本。利用这些成本，我们估算了按商品种类划分的部门特定贸易的贸易成本。我们成功地重建了部门特定的贸易为每种类型的商品，通过最大化配置熵与估计的成本。在WIOD中，相同的工业部门之间的贸易活跃。另一方面，在NBER-UN，邻国之间的贸易活跃。这似乎是一个矛盾。我们按照商品类型对重建的行业特定贸易网络进行了社区分析。共同体分析表明，产品在邻国的相同行业部门之间进行了积极的贸易。因此，观察到的妇女组织发展网络和国家经济研究所-联合国网络的社区结构特征是互补的。
We developed a model to reconstruct the international trade network by considering both commodities and industry sectors in order to study the effects of reduced trade costs. First, we estimated trade costs to reproduce WIOD and NBERUN data. Using these costs, we estimated the trade costs of sector specific trade by types of commodities. We successfully reconstructed sector-specific trade for each types of commodities by maximizing the configuration entropy with the estimated costs. In WIOD, trade is actively conducted between the same industry sectors. On the other hand, in NBER-UN, trade is actively conducted between neighboring countries. This seems like a contradiction. We conducted community analysis for the reconstructed sector-specific trade network by type of commodities. The community analysis showed that products are actively traded among same industry sectors in neighboring countries. Therefore the observed features of the community structure for WIOD and NBER-UN are complementary.
