Energy resources are dynamic sources of development of human society and economy.In reality, spatial distribution of energy resources is often uneven, and spatial dislocation ofenergy production and consumption is a more common phenomenon. So, the flow process ofenergy resources, including spatial displacement process and material utilization process, is themain mode of exploitation and utilization of energy resources, which is also an important directionin the study of resources flow. Currently, the study of energy resources flow mainly concernsof primary energy resources, such as coal and oil, which is of significant representativeness,typicality and important practical application value in the study of resources flow. Theyare widely used in macroeconomic analysis, energy policy and strategy development, transportationplanning, logistics and trading plan, analysis of energy efficiency, environmental valueaccounting, energy saving and emission reduction and other areas of policy formulation and decision-making.
The article combed and summarized research efforts of energy resources flow, and elaboratedthe content, focal points and characteristics of energy resources flow study from all relateddisciplines'research perspectives. It indicated that geonomics, geography of communication,logistics, industrial economics and industrial ecology were most closely related subjects tothe study of energy resources flow.
Next, this article elaborated the main contents of energy resources flow study from fouroutlines including the characteristics, mechanisms, effect, optimization and regulation. Accordingto the above-mentioned, the study of energy resources flow from various subjects mademuch enrichment and development on the theoretical study of resources flow. Therefore, this articleindicated that the directionality of resources flow and elements deconstruction of spatialstructure of resources flow should be a useful addition to the resources flow theory.
In discussion on energy resources flow research framework, Cheng Shengkui made ananalysis on resources flow into two main flow forms, one of which put resources flow resolveto horizontal flow, and another vertical flow. Horizontal flow occurred when resources made adisplacement in different geographic space. And vertical flow occurred when resourcesachieved of form, features and value's transformation in the process from original state resourcesto wastes. That was not only an accurate analysis on resources flow connotation, but also providinga basic research framework for thereafter resources flow empirical research. This articlesupposed that existing study framework of energy resources flow was consistent to the frameworkof vertical and horizontal analysis of resources flow. Their vertical and horizontal researchconducted independently and formed two very different research styles. At the sametime, the article pointed out that this research framework lacked of effective contact mechanismswhich could link up vertical and horizontal analysis. On the basis of the earlier studies,this paper finally put forward some gradual goals and outlook contents of the future energy resourcesflow research.
