报告题目:Examining Sectoral Structure Differences Between China and Japan Through Network Analysis
报告摘要:Comparisons of the economic structures between China and Japan have consistently intrigued development economists. In order to explore the sectoral distinctions between these two nations from 1995 to 2018, we analyzed the annual input-output tables (IOTs) to construct weighted and directed input-output networks (IONs). This approach allowed for more nuanced network analyses. Variations in strength distributions highlighted differences in economic interactions across sectors. The weighted, directed assortativity coefficients illustrated the tendency of similar sectors to connect. Adjustments in PageRank centrality helped pinpoint the key sectors, while community detection techniques shed light on the clustering patterns within the sectors. As expected, the analysis identified manufacturing as the pivotal sector in China, whereas Japan leaned towards the services sector. However, upon closer examination, each country showed distinct sectoral developments. Despite these differences, the sectoral communities in both China and Japan displayed remarkable stability throughout the period studied.
王涛简介:王涛,教授,统计学博士,英国雷丁大学访问学者,山西财经大学统计研究院副院长,中国工业统计学教学研究会理事,中国青年统计学家协会理事,入选山西省“三晋英才”支持计划,获2020年全国大学生市场调查与分析大赛十周年“优秀指导教师”称号,获得“山西省优秀博士学位论文”荣誉。国家社会科学基金重大项目子课题负责人,主持2项国家社科基金项目和10余项省部级课项目,在《统计研究》和《Physica A: Statistical Mechanics and its Applications》等国内外期刊发表数十篇学术论文。
报告会中,王教授为我们分析了中国与日本的年度投入产出表(IOT),以构建加权和定向投入产出网络(IONs)。这种方法允许进行更细致的网络分析。力量分布的差异凸显了各部门经济互动的差异。加权的、有向的分类系数说明了相似部门之间的联系趋势。该分析得出制造业为中国的关键行业,而日本则倾向于服务业。经过调查审查发现,每个国家都显示出不同的发展方向。尽管存在这些显著差异,但中国和日本的部门指标值都表现出显著的稳定性。
王教授的报告内容主题鲜明,向同学们展示了新的研究方向和研究内容,使同学们产生了极大的兴趣。同时,报告会后,老师和同学也对该话题展开了激烈的讨论。通过此次报告会,同学们对该方向的认识有了更深的了解,拓展了学生们的思维领域。
