Research On Material Flow Analysis And Dynamic Management Model

As a new form of economy, circular economy is based on recycling resources and environmental capacity and meets the mankind demand for materials in the new style of material metabolism, in which producers, consumers and decomposers efficiently coordinate. Material metabolism becomes the core of research on circular economy. As an important method of research on material metabolism, Material Flow Analysis is becoming the significant approach as well the dynamic material management model turns into the means of developing circular economy. So the contents of the paper are analyzing material low in circular economy and carries on the dynamic management model.At first, he background and significance of the research is stated, and the present conditions in domestic and overseas are summarized. Three analysis models about material flow are introduced, which are STRAMS(Statistical Research for Analysing Material Streams),STAF(Stock And Flow )and Input-Output Analysis. Material flow management models based on Input-Output analysis are drawn into the paper, which includes static Input–Output material flow management model, dynamic Input-Output management model and dynamic Input-Output feedback model. With the aid of dynamic models, the stocks of the individual progress and changes on time are reflected.Because the previous dynamic Input-Output feedback model established on the outflows, only adjusts the outflows and stocks in the economic system, which doesn't concern the inflows of resources from external. So an improved dynamic Input-Output management model based on the inflows is set up, in which the increase of material flows of individual progress is achieved by using internal stocks and inflows from external. With the internal stocks increasing, the demand for material...
