This book from the current cycle of economic planning issues need to be resolved to start making full use of System Integration thinking, the planning and construction of circular economy as a systems engineering, advanced experience at home and abroad, from the economic cycle in the operating principles of the various aspects of complex system analysis cut from a cycle, circulating and small cycles of view, review and summarize the regional recycling economy, towns, parks, businesses, industries, resource consumption, support, supervision and theoretical foundation level. Sufficient basis for economic planning cycle to be solved by a complex system problem, use System Integration idea proposed model group technology system, construction solving framework all the problems in the whole cycle of economic planning, and give full play to the model group each model yuan Advantages , in connection with the practical problems involved in economic planning cycle characteristics, ecological footprint technology, self-organizing mining, Shift-share industry analysis, industry structure deviation technology, industry association structure analysis, comprehensive analysis of urban and rural integration process technology, ecological comprehensive zoning technology, time series forecasting analysis, neural network technology evaluation and analysis, input-output dynamics simulation technology evaluation and analysis, technical analysis and econometric forecasting systems analysis discusses the cycle of economic planning in scientific problem solving technique, while each technique solving specific problems for economic planning cycle are given detailed examples of solving. Comprehensive recycling economy theory and technology, according to the cycle of economic planning, at different levels gives the cycle of economic planning, recycling economy construction of the park and typical scheme typical business cycle of economic embodiment of a typical area for all levels of the cycle of economic planning provided actionable, great reference value cycle
