基于物理学中的场理论,以2007年甘肃省投入产出表为主要研究对象建立产业关联梯度场模型,计算甘肃省42个行业的产出梯度、影响力梯度、感应度梯度及其排名,从经济空间梯度的角度对各产业进行剖析,并以产业关联梯度场模型对甘肃省各产业在经济空间中的地位、作用及其动态变化情况进行量化分析,对今后不同产业在产业经济空间中的地位、作用、影响及其变化情况做出预测,并对甘肃省三次产业在经济空间中的结构进行分析,为今后甘肃省产业结构的战略调整提供决策依据。
Using the input-output table of Gansu Province in 2007, the industry relevance gradient field model is built and the output gradient, influence gradient, sense degree gradient and their rank of the 42 industries are calculated based on the field theory in physics. From the angle of the economic spatial gradient each industry is an- alyzed, and the status, function and dynamic changes of each industry in the economic space are analyzed quantita- tively by the industrial gradient field model and predicted for the future in Gansu Province. And the structure of the three industries' in the economic space is analyzed to provide the decision-making basis for the strategy adjustment of the industrial structure in Gansu Province.
