摘要：The five central cities--Beijing, Tianjin, Shanghai, Guangzhou and Shenzhen--of the three most important strategic regions in China, namely Beijing-Tianjin-Hebei metropolitan region, the Yangtze River Delta and the Pearl River Delta, are taken as a comparative analysis on urban producer services＇ competitiveness, especially focusing on the comparative advantages and disadvantages of producer services in Beijing. Firstly, based on an integrated indicator system including one objective hierarchy, four standard hierarchies and 35 indicator hierarchies, the study applies factor analysis model and analytic hierarchy process model reformed by entropy technology to measure the comprehensive competitiveness of producer services in the above five cities. Secondly, Beijing has comparative advantages of capital resource, industrial base, scientific research resource and market scale, since it takes the first place of the five cities in the comprehensive competitiveness of producer services, the competitiveness of industrial development, business environment and living environment, only inferior to Shanghai in the competitiveness of talent capital. Thirdly, Beijing has comparative disadvantages in the level of producer services development, urban innovation capability and living environment. Finally, five proposals are put forth to enhance the competitiveness of producer services in Beijing, namely perfecting the system of laws and statutes, supporting the development of industry association, implementing scientific development planning, introducing preferential fiscal and taxation policies and strengthen- ing human capital reserve.
