Green GDP Linear Programming Model And Its Solution's Policy Enlightenment

It is a big contradiction that energy and environment factors are having more and more influence on the development of Chinese economy. The"high input, high consume, low output, low benefit"way of economic development is difficult to maintain. Facing the day-by-day tighter energy and environment problems, how to make a reasonable plan by which we can achieve our social and economic targets and reduce energy consumption and pollution at the same time as far as possible is a problem worthy of being studied and solved urgently. So, this paper has done the following concrete works:Firstly, the author considers energy, environment and economy factors, bases the complete value green input-output table on the input-output, energy and environment data in 2005 which were published by China Statistic Bureau. The author calculates these data strictly, puts four departments'data of energy consumption, energy saving, pollution emission and pollution administration into the original input-output table, works out the complete value green input-output table.Secondly, according to the 2020's social and economic targets which are made by the government, this paper uses the real data, especially the data of the green input-output table, sets up the linear programming model whose goal is maximum of Green GDP, then applies the model into practice. The model has obtained the best economic structure under the Green GDP's target and certain constraints which can provide industry-level, detailed and valuable information for the Government.At last, based on the foregoing study, this paper comes up with some suggestions and countermeasures to deal with the energy and environment problems, including developing energy-environment accounting, economic structure adjustment, and cyclic economy development, making market in action in the terminal process of environment administration and energy consumption and so on.
