中文摘要：

以2007年中国投入产出表为基础,运用威弗综合指数法构建了中国产业部门间联系网络,并对以煤炭开采和洗选业等为主的5个主要能源产业的网络特征进行分析。结果发现：1）相对于一次能源生产部门,二次能源生产部门对国民经济的影响范围和影响力都更广泛和强烈,但一次能源生产部门产业节点间网络密度大、资源流通效率较高;2）各能源产业本身也是高耗能产业,不仅对自身有较强的依赖性,各能源产业之间也存在很强依赖性;3）产业网络效益的提升是所有节点共同作用的结果,能源产业的发展需要重视基础性工业及第三产业的配套发展。

英文摘要：

Based on input- output table of China in 2007,we used Weaver Complex Index to build a Chinese industries network,and analyzed 5 main energy industries network attributes. Results indicated that firstly,compared with primary energy industries,the secondary energy industries had more abroad and violence influence on national economy. However,higher net density between primary energy industries nodes made it had better resource circulation efficiency and yields. Secondly,energy industries consumed plenty of energy too; all energy industries not only had strong dependence on themselves but also on other energy industries. Thirdly,the improvement of industries network efficiency was the results of all nodes,so the development of China energy industries need strengthen cooperation with tertiary industries and basic industries.
