【摘要】：城市經(jīng)濟(jì)快速穩(wěn)步增長(zhǎng)的重要因素之一就是城市的產(chǎn)業(yè)結(jié)構(gòu)是否合理。近些年，延安市經(jīng)濟(jì)在增長(zhǎng)的過(guò)程中產(chǎn)業(yè)結(jié)構(gòu)變化并不明顯。作為西北地區(qū)中的中小城市，延安市發(fā)展起步晚，仍處于城市化的初級(jí)階段，但有很多經(jīng)濟(jì)發(fā)展的有利條件。本文通過(guò)數(shù)學(xué)模型的建立來(lái)優(yōu)化各行業(yè)的生產(chǎn)規(guī)模，從而使延安市經(jīng)濟(jì)在可持續(xù)發(fā)展的前提下快速發(fā)展。 首先，，結(jié)合區(qū)域經(jīng)濟(jì)學(xué)中產(chǎn)業(yè)結(jié)構(gòu)理論對(duì)延安市產(chǎn)業(yè)結(jié)構(gòu)現(xiàn)狀進(jìn)行了分析，并用SAS軟件的相關(guān)分析得到三次產(chǎn)業(yè)中前10個(gè)主要行業(yè)為：農(nóng)業(yè)、林業(yè)、牧業(yè)、漁業(yè)、服務(wù)業(yè)、工業(yè)、建筑業(yè)、交通運(yùn)輸倉(cāng)儲(chǔ)郵政業(yè)、批發(fā)零售住宿餐飲業(yè)和旅游業(yè)；然后，運(yùn)用投入產(chǎn)出知識(shí)建立基本的產(chǎn)業(yè)結(jié)構(gòu)線性優(yōu)化模型，選取為能源、水資源、土地資源、資金、勞動(dòng)力、環(huán)境等6個(gè)因素為約束條件，約束量用Matlab軟件進(jìn)行函數(shù)擬合預(yù)測(cè)得到；其次，由于基本模型的建立在現(xiàn)實(shí)中并不完全成立，所以本文對(duì)模型進(jìn)行了改進(jìn)，得到逐年最優(yōu)線性優(yōu)化模型和周期型線性優(yōu)化模型；最后，對(duì)改進(jìn)后的模型進(jìn)行數(shù)值求解及結(jié)果分析，得出周期型線性優(yōu)化模型比逐年最優(yōu)線性優(yōu)化模型更好，更符合產(chǎn)業(yè)結(jié)構(gòu)的可持續(xù)發(fā)展。同時(shí)本文對(duì)延安未來(lái)幾年經(jīng)濟(jì)發(fā)展給出建議：政府應(yīng)加大對(duì)工業(yè)、批發(fā)零售住宿餐飲業(yè)和旅游業(yè)的投入與發(fā)展，對(duì)于農(nóng)業(yè)、林業(yè)、牧業(yè)、漁業(yè)、服務(wù)業(yè)、建筑業(yè)、交通運(yùn)輸倉(cāng)儲(chǔ)郵政業(yè)應(yīng)基本保持原來(lái)的生產(chǎn)規(guī)模。
[Abstract]:One of the important factors of the rapid and steady growth of urban economy is whether the industrial structure of the city is reasonable.In recent years, Yanan economy in the growth process of industrial structure change is not obvious.As a small and medium-sized city in Northwest China, Yanan City started late and is still in the primary stage of urbanization, but there are many favorable conditions for economic development.This paper optimizes the production scale of various industries through the establishment of mathematical model, so as to make the economy of Yan'an develop rapidly under the premise of sustainable development.First of all, based on the theory of industrial structure in regional economics, this paper analyzes the present situation of Yanan's industrial structure, and finds out that the top 10 main industries of the three industries are agriculture, forestry, animal husbandry, fishery and service industry by using the correlation analysis of SAS software.Industry, construction, transportation, storage and post industry, wholesale and retail accommodation, catering and tourism; then, using input-output knowledge to establish a basic linear optimization model of industrial structure, selected as energy, water resources, land resources, capital,Six factors, such as labor force and environment, are the constraint conditions. The constraint is predicted by Matlab software. Secondly, because the basic model is not fully established in reality, the model is improved in this paper.The optimal linear optimization model and the periodic linear optimization model are obtained. Finally, the improved linear optimization model is solved numerically and the results are analyzed. It is concluded that the periodic linear optimization model is better than the annual optimal linear optimization model.More in line with the industrial structure of sustainable development.At the same time, this paper gives some suggestions for the economic development of Yan'an in the coming years: the government should increase the investment and development of industry, wholesale and retail accommodation, catering and tourism, as well as agriculture, forestry, animal husbandry, fisheries, service industry, construction, etc.Transportation, storage, postal industry should basically maintain the original scale of production.
