Industrial Linkages and Comparative Advantages in Beijing's Industries
利用北京投入产出表数据，研究发现1987-2002年间劳动和资源密集型制造业优势减弱，资本和技术密集型产业优势增强，产业关联强化了基于资本、知识和技术要素的比较优势。
Economic base theory contends that urban economic growth is attributed to external demand and industrial comparative advantages lie in basic sectors. Using net exports of industries computed from Beijing Input-Output tables, this study found that labor and resource intensive manufacturing industries have been losing its momentum while capital and technology intensive industries have gaining advantages during the period of 1987-2002. Producer services and knowledge intensive services have been replacing traditional services as the critical sectors. Statistical results indicate that strong industrial linkages have enhanced Beijing's comparative advantages,which are based in production factors of capital, knowledge and technology.
