中文摘要：

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年中关物流业在国民经济产业影响力、产值、C．DP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。

英文摘要：

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.
