Dynamic input - output model analysis of three industrial structures of heilongjiang province 黑龍江省3次產業結構的動態投入產出模型分析
3 . a sensitivity analysis for solutions to dynamic input - output model is performed 對動態投入產出模型的解及其靈敏度問題進行了分析。
The dynamic input - output model had been put forwarded by w . leontief . since the problem of its balanced solution has not been solved , its application is very limited 動態投入產出模型最早由w . leontief提出,因其穩定解問題沒有解決,使它的應用十分有限
First , we consider a dynamic input - output model with deterministic consumption vector s ( t ) , random consumption coefficient matrix and random investment coefficient matrix which the time lag is one 首先,對時滯為1的動態投入產出模型,將隨機因素、消費向量考慮進去,研究時滯為1且帶確定性消費的前向延遲型隨機動態投入產出模型
Consider the randomness of economic development , in this paper , we study a random dynamic input - output model with consumption , and get the conclusion that the economic balanced growth solution for this model does not exit 考慮到現實中經濟發展變化的隨機性,本文對帶消費的時滯為1的隨機動態投入產出模型穩定增長解的存在性問題進行了深入研究,用隨機分析的方法得到了經濟穩定增長解不存在的結論
Under some natural weak assumptions that do not require the technological coefficients matrix is indecomposable , the fact that the dynamic input - output system is not asymptotically stable and the closed dynamic input - output model exists a balanced growth solution is proved 利用矩陣特征值理論和廣義系統理論,在相對弱的條件下(不需要直接消耗系數矩陣不可分解) ,證明了動態投入產出系統不是漸近穩定的。
A dynamic input - output model with random consumption vector s ( t , ) , random consumption coefficient matrix and random investment coefficient matrix which the time lag is one has been discussed . by means of modern stochastic analysis and markov process , it has been proved that the random dynamic input - output model does not have a balanced growth solution 對具有隨機消費向量s ( t , ) ,隨機投入產出消耗系數矩陣、隨機投資系數矩陣的動態模型,利用現代概率分析、馬氏過程等工具,證明了其經濟穩定增長解不存在的結論
Moreover , the paper out stretched its model : it has accounted the produce solicitation coefficient of ten departments in shannxi and established the nonlinear dynamic input - output model of shannxi ten departments and the 2010 requirement forecast model for modenized hous - ing industry in shannxi province 此外,本文還對所建立的模型進行推廣:計算出陜西省十部門各自的生產誘發系數,建立陜西省十部門非線性動態投入產出模型及陜西省住宅產業現代化2010年需求預測模型。
