全产业链下物流业服务经济发展的贡献

摘要

国民经济发展离不开物流业，物流服务在错综复杂的产业链中起着不可或缺的“桥梁”作用。本文运用投入产出技术，首次推导并分解出全产业链下物流业的服务贡献值完耗表，计算和比较了2010年中美物流业在国民经济产业影响力、产值、GDP及就业增长等方面的贡献率，分析了1992～2010年中国物流业服务贡献率的变动情况及低估水平。研究表明我国物流业虽然自身发展水平相对落后，但在全产业链中服务经济发展的贡献却显著地高于美国。%It is hard to develop without logistics industry for national economy . Logistics services play an important role in intricate industrial chains . This paper applies the input-output technique to deduce and decompose the completely consuming table of logistics con-tribution to the whole industrial chain , calculating and comprising the logistics contribution to national economic influence and the growth of output value , GDP and employment between the China and the United States in 2010 . Then we analyzes the changes and undervalued lo-gistics contribution from 1992 to 2010 . The results show that Chinese logistics contribution to the whole industrial chain is significantly high-er than that of the United States , although its development level is relatively backward .
