摘要
贸易增加值分解提供了研究GVC的新视角和新数据。利用最新的贸易增加值分解方法对世界投入产出表(WIOD)分解所获得的数据,分析了价值链的国家和地区差异及演变趋势。实证发现:(1)从VSS的来源视角,GVC在很大程度是地区价值链或者发达国家和地区价值链,但全球化的趋势在加强。(2)VSS与地区一体化程度正相关,且后者能显著提升来自地区内的增加值比重。(3)相对于地区内发达国家,发展中国家隶属于国内价值链和全球价值链的行业数更少,但地区价值链类型的行业数更大。对于劳动密集型制造业,发达国家在扩大其全球外包的进程,发展中国家的价值链也在完善。但对于技术密集型制造业和现代服务业,这两类国家的竞争力差距还较大。
Trade in value- added decomposition provides new methods and data for Global Value Chain（ GVC）. Based on the World Input- Output Database（ WIOD）,the paper obtains value added data from the latest approach that decomposes bilateral sector level gross export into various terms. Besides the trend of development,we also analyze differences of value chains among different countries and regions. Main findings are as follows. First,based on the source of VSS,GVC is regional value chain or big countries and regional value chain,but it＇s more and more global. Second,VSS is positive related to regional economic integration and the later can increase value added coming from the region. Third,compared to developed countries of the region,developing countries have less sectors belonging to domestic value chain or global value chain,but have more sectors belonging to regional value chain. Finally,developed countries are outsourcing more tasks of their labor- intensity manufacturing to developing countries and the later also are more competitive in these sectors. But the stories are different for technology- intensity manufacturing or modern service sectors.
