产业联系与北京优势产业及其演变

根据经济基础理论,城市经济增长源于城市外部需求.一个城市的比较优势体现在服务于外部市场的产业中.论文基于北京市投入-产出表,依据产业净流出,分析了北京市产业的比较优势及其变化.过去15年来,北京的劳动密集型和原料型制造业的优势逐渐丧失,以电子通信设备、化学工业和机械设备制造业为代表的资本和技术密集型产业正成为优势产业;服务业中,传统服务业从20世纪80年代的优势地位退居劣势地位,取而代之的是知识密集型的生产者服务业,如金融业、软件和计算机服务业、信息传输服务业、广告业、房地产开发业、商务服务、科技交流和推广服务业等.产业联系是北京产业比较优势的显著影响因素,资本、知识和技术是北京市产业比较优势的投入支撑.

Industrial Linkages and Comparative Advantages in Beijing's Industries

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.
