【摘要】：產(chǎn)業(yè)結(jié)構(gòu)是經(jīng)濟(jì)體系發(fā)展中不可或缺的要素,研究產(chǎn)業(yè)結(jié)構(gòu)是分析一國或地區(qū)經(jīng)濟(jì)發(fā)展的內(nèi)在要求。合理的產(chǎn)業(yè)結(jié)構(gòu)是促進(jìn)經(jīng)濟(jì)健康、穩(wěn)定、持續(xù)、協(xié)調(diào)發(fā)展的關(guān)鍵�？v觀甘肅省產(chǎn)業(yè)結(jié)構(gòu)的演變歷程,可以發(fā)現(xiàn)在國家戰(zhàn)略部署的影響下其形成了自身獨(dú)有的特點(diǎn)。通過分析甘肅省產(chǎn)業(yè)結(jié)構(gòu)的特點(diǎn)和演變機(jī)制,找出其在演變歷程中存在的問題,對于產(chǎn)業(yè)結(jié)構(gòu)的合理化升級具有重要的意義。本文利用復(fù)雜網(wǎng)絡(luò)理論研究了每個(gè)產(chǎn)業(yè)部門在復(fù)雜的產(chǎn)業(yè)系統(tǒng)網(wǎng)絡(luò)中的地位和作用,從而從更微觀的層面剖析了甘肅省產(chǎn)業(yè)結(jié)構(gòu)的演變規(guī)律,具有重要的現(xiàn)實(shí)意義�；谕度氘a(chǎn)出表研究產(chǎn)業(yè)結(jié)構(gòu)的方法有很多種,其研究的角度也各不相同,但都存在一些問題。本文結(jié)合復(fù)雜網(wǎng)絡(luò)的相關(guān)理論來研究產(chǎn)業(yè)結(jié)構(gòu),避免了使用其他方法的局限性。首先,構(gòu)建一個(gè)以產(chǎn)業(yè)部門為節(jié)點(diǎn),以真實(shí)的投入產(chǎn)出值為紐帶的有向加權(quán)網(wǎng)絡(luò);其次,根據(jù)復(fù)雜網(wǎng)絡(luò)的定量指標(biāo),計(jì)算產(chǎn)業(yè)結(jié)構(gòu)網(wǎng)絡(luò)的統(tǒng)計(jì)屬性,包括:度及度分布、權(quán)及權(quán)分布和聚類系數(shù);最后,結(jié)合對實(shí)際經(jīng)濟(jì)的解釋將計(jì)算出的定量指標(biāo)值解釋為:產(chǎn)業(yè)部門的演變、產(chǎn)業(yè)聯(lián)系的演變以及產(chǎn)業(yè)子群的演變,給產(chǎn)業(yè)結(jié)構(gòu)網(wǎng)絡(luò)的特征值賦予一定的經(jīng)濟(jì)意義,并結(jié)合甘肅省產(chǎn)業(yè)結(jié)構(gòu)的現(xiàn)狀,理論聯(lián)系實(shí)際,對甘肅省的產(chǎn)業(yè)結(jié)構(gòu)演變的特點(diǎn)和趨勢做深入的分析。甘肅省的產(chǎn)業(yè)結(jié)構(gòu)變動(dòng)具有階段性的特點(diǎn),與我國產(chǎn)業(yè)結(jié)構(gòu)的變動(dòng)方向一致,但變動(dòng)速度卻滯后于我國的平均水平�，F(xiàn)階段甘肅省產(chǎn)業(yè)部門之間的聯(lián)系越來越緊密,但各部門在產(chǎn)業(yè)結(jié)構(gòu)中的地位越來越不平等,尤其是第二、三產(chǎn)業(yè)部門之間。從研究結(jié)果可以看出第二、三產(chǎn)業(yè)在國內(nèi)生產(chǎn)總值中所占的比重沒有明顯的變化,但各產(chǎn)業(yè)內(nèi)部部分產(chǎn)業(yè)部門的重要性卻有很大的變化,尤其是服務(wù)業(yè)內(nèi)部一些公共基礎(chǔ)服務(wù)的重要性要低于現(xiàn)代服務(wù)業(yè)。
[Abstract]:The industrial structure is an indispensable element in the development of the economic system. The study of the industrial structure is an inherent requirement for the analysis of the economic development of a country or region. A reasonable industrial structure is the key to promoting the economic health, stability, sustainability and coordination of development. A survey of the evolution of the industrial structure in Gansu can be found under the influence of the national strategic deployment. By analyzing the characteristics and evolution mechanism of the industrial structure of Gansu Province, we find out the problems that exist in the evolution process, and have important significance for the rationalization and upgrading of the industrial structure. This paper uses the complex network theory to study the position and function of each industrial department in the complex industrial system network. It is of great practical significance to analyze the evolution law of industrial structure in Gansu province from a more micro level. There are many ways to study industrial structure based on input-output table, and the angle of its research is different, but there are some problems. This paper studies the industrial structure and avoids the use of the related theory of complex network. The limitations of other methods. First, construct a directed weighted network with industrial sector as a node and real input and output value as the link. Secondly, according to the quantitative index of complex network, the statistical properties of industrial structure network are calculated, including degree and degree distribution, weight and weight distribution and clustering coefficient; finally, it combines the explanation of the actual economy. The quantitative index values are explained as: the evolution of the industrial sector, the evolution of industrial relations and the evolution of industrial subgroups, giving certain economic significance to the characteristic values of the industrial structure network, and combining the status of the industrial structure of Gansu Province, linking the theory with the practice, and making an in-depth analysis of the characteristics and trends of the evolution of the industrial structure in Gansu province. The change of industrial structure in Gansu province has the characteristics of stages, which is in line with the changing direction of China's industrial structure, but the speed of change is lagging behind the average level of our country. The link between the industrial departments of Gansu is becoming more and more close at the present stage, but the position of each department in the industrial structure is becoming more and more unequal, especially in the second, third industry department. From the result of the study, it can be seen that the proportion of the second, third industry in GDP has not changed obviously, but the importance of some industrial sectors in each industry has changed greatly, especially the importance of some public basic services in the service industry is lower than the modern service industry.
