基于MSIASM方法的沈阳城市代谢研究

本文采用社会代谢多尺度综合分析方法分析沈阳经济的演化过程。研究表明,1978～2003年,沈阳投入在第一、二产业的人类活动时间(HA值)所占比重有所下降;而第三产业的比重有增加趋势,但不明显;同时投入在家政部门的人类活动量(包括所有非经济活动)逐年下降;1978～1995年每个工作时间负担的非工作时间数量越来越小,1995～2003年每个工作时间负担的非工作时间数量越来越大,这与沈阳市的经济发展规律一致;沈阳社会/劳动生产率显著增加,社会经济生产率、社会劳动生产率、农业部门劳动生产率、生产部门劳动生产率,以及服务与管理部门的劳动生产率增长了20～30倍,说明沈阳的社会经济发展主要靠工业的拉动力。

A MSIAM based study on Shenyang City's metabolism

The methodology of multi-scale integrated analysis of societal metabolism (MSIASM) was employed to study the recent social evolution of Shenyang city. The result showed that from 1978 to 2003 the total inputs of primary industry and secondary industry decreased, while the total inputs of household sector and tertiary industry increased;from 1978 to 1995 the overhead of human activity time decreased, while the same value from 1995 to 2003 increased with the rapid development. This matches the same trend of Shenyang's economic development. Our research findings clearly indicate that both social and economic productivity has significantly increased, namely, the overall social labor productivity, labor productivity in agriculture sector, in manufacturing sector, and in service and government sector increased by 20～30 times. The above results show us that manufacturing industry was the main driver for Shenyang's rapid development.
