摘要
面对当今社会人类对资源的过度使用以及对生态环境的破坏,航运业必须要充分思考应如何提升其生态效用。认为应将航运企业作为节点放入生态系统的框架下,并将与其合作企业和货主的联系充分考虑在其中,才能创造真正意义上的生态效用。通过对生态物流定量的随机前沿模型加以数学描述,得到了新的内涵,利用"投入-产出"模式分析航运企业内部及航运企业与其他节点发生联系时的生态效用及其影响因素。通过该模型可得出影响因素对生态效用的贡献率,经排序,可得到船公司与不同节点合作联系时生态效用的优劣。
Excessive use of resources is harming ecological environment,so shipping industry should consider seriously how to increase its ecological effectiveness.This paper suggests that shipping company should be put into the framework of a ecological system and examined in conjunction with related businesses and customers which comprises itself and its relation with other nodes and customers so as to find out real ecological effectiveness.New knowledge of ecological logistics is obtained with a stochastic frontier analysis model.Ecological effectiveness of a shipping company alone and the ecological effectiveness of a company connected with other nods are analyzed by means of the ＂input-output＂ mode analysis.The influencing factors are studied.The contributions of influencing factors to the ecological effectiveness can be found with the mathematical model. The results under different combination can be taken as the criterion for selecting cooperation nods.
