以2002、2005和2007年京、津、沪、渝的投入—产出表为基础,运用投入—产出法分析生产性服务业发展对城市经济"减物质化"过程的影响。通过比较发现,生产性服务业发展与城市经济发展水平正相关,并有利于实现"减物质化",但粗放式经济发展模式下制造业对生产性服务业的需求不足使城市经济对物质资源形成高度依赖。因此,转变经济发展方式,增加生产过程中的生产性服务投入,有助于在提高经济增长效率的同时实现"减物质化"目标。
In 2002, 2005 and 2007 in Beijing, Tianjin, Shanghai and Chongqing of the input - output table as the basis, using the input - output analysis of producer services development of city economy "dematerialization" influence. By comparison, producer serv- ices development and city economic development level are correlated, and conducive to the realization of "dematerialization". However, the extensive economic development mode of manufacturing to the producer services demand that city economy to get rid of the material resources highly dependent on. Therefore, we must change the mode of economic development, increased producer services inputs in the process of production in order to improve the efficiency of economic growth and achieve"dematerialization"target.
