基于“期货＋制造”视角的我国PVC产业链模式研究

在石化行业高成本支撑时代下，“期货＋制造”这一新颖产业模式是我国PVC产业可持续发展的路径选择。本文基于产业链升级作用机理提出的以期货工具为纽带的企业价值链模型和立体旋转“钻石”模型，构建了我国PVC期现市场共同健康发展的理论分析框架。实证结果显示，PVC期货价格发现功能有限，回避风险功能效果较差，现货市场仍起主要作用，因此PVC期现市场之间的互动还需进一步加强。     

The need for combining IEA and IE tools: The potential effects of a global ban on PVC on climate change

Over the last decades the concepts of Integrated Environmental Assessment (IEA) and Industrial Ecology (IE), both claiming to provide analyses and solutions for sustainability issues, have been developed separately as they emerged in response to questions from different policy-fields. In both fields, specific tools are used to support national and international environmental policy. The focus of IEA and IE tools, however, is different. IEA tools focus on one or a limited number of specific environmental issues. They often model the chain environmental processes with high spatial (and temporal) resolution, but have a low resolution for the material structure of the economy and only partly take into account indirect effects that occur via physical and socio-economic linkages. IE tools take into account all environmental issues related to a specific substance or product. They have a high resolution for the material structure of the economy and take into account indirect effects that occur via physical linkages, however, their environmental modelling is very limited. Both IE and IEA tools have proven to be very useful and neither is superior to the other. However, a combination of both can provide additional information that can be used for more effective policy making. We use the case of a hypothetical world-wide ban on PVC to show that a measure that is not directly related to climate change could still have significant climate effects. This indirect effect is a result of the linkages of material flows in society. We show that IEA tools are not well suited to include these types of effects and that IE tools can fill this gap partially. What is really needed is a broader systems perspective that takes into account the full range of possible side-effects of environmental policy measures.
