广义物流与天然气管道输送网络经济悖论

Economy Paradox Between Logistics and Natural Gas Pipeline Network

从"广义物流"概念扩展出发,提出"网络状产业"和"网络型产业"的概念,用节点双向连通的容易程度加以界定,并按照E的大小对广义网络状产业进行了排序。分析了管道输送业的本质技术特征与网络型产业的异同,指出管道输送网络和连接起来的两个网络都不具有梅特卡夫递增效应,即天然气管道输送业不具有网络型基础产业边际报酬几何递增的经济特性,因此对管道输送业只能按照一般具有规模经济性、范围经济性的产业予以监管。

Having expanded from generalized logistics, it presented the concept o f 'Network-industry' and 'network-type industry', defined the extent by using tw o-way connectivity and sorted Generalized Network-industry by E Size. It analyze d the essential technical features of pipeline transportation industry and the d ifferences between network-type industries. It pointed out piping network and ot her two linked networks would not have the Metcalfe incremental effect, namely n atural gas pipeline transportation industry have no marginal return geometric in cremental economic characteristics compared with network infrastructure industri es, so the industry can only be supervised being a common industry with economie s of scale.
