中国产业强关联复杂网络建模及特征演化分析(2000—2018)

An Analysis of the Modeling of China’s Industry Complex Network with Strong Industrial Linkages and the Revolution of Characteristics(2000—2018)

文章通过构建2000—2018年中国产业强关联复杂网络,对关键产业、关键产业链、区块结构、产业类型等方面的演化特征进行深入研究,分析数字经济产业在网络中的地位。结果显示:中国产业系统在供给侧存在更大的不对称性,少数枢纽产业占据着非常重要的位置;农业与上游行业快速融合发展并对关键产业链起到强有力的拉动作用;制造业仍然是中国的重点支撑产业,有较强的需求拉动和供给推动作用,其中医药、药用化学、化学用品制造以及其他机械设备制造业发挥着重要作用,而科学技术相关产业的需求拉动和供给推动能力都较弱。数字经济产业分析显示,数字硬件产业的供给推动能力大于需求拉动能力,且在强产业链中占据关键地位,对打通产业系统的循环起着非常重要的作用,但数字软件产业与各产业的融合有待加强。

This paper constructs China’s industry complex network with strong industrial linkages from 2000 to 2018,conducts a deep study of the evolution characteristics of key industries,key industrial chains,block struc⁃tures,industry types,etc.,and further analyzes the position of digital economy industry in the network.The results show that:There is greater asymmetry on the supply side in China’s industrial system,and a few hub industries oc⁃cupy very important positions;agriculture and upstream industries develops in rapid combination,and plays a strong driving role in key industrial chains;manufacturing is still the key supporting industry in China,which plays a pow⁃erful role in driving demand and pushing supply,among which pharmaceutical,medicinal chemistry,chemical prod⁃ucts manufacturing and other machinery and equipment manufacturing play an important role while science and technology related industries are weak in both demand-pulling and supply-pushing capacities.Digital economy in⁃dustry analysis shows that the digital hardware industry has a greater ability to promote the supply of other indus⁃tries than to pull the demand,and occupies a key position in the strong industrial chain,which plays a very impor⁃tant role in establishing the cycle of the industrial system,but the integration of digital software industry and various industries needs to be strengthened.This paper has reference significance for the strategic design and precise imple⁃mentation of the whole industrial chain,ensuring the stability of the industrial chain and supply chain,improving the resilience of the industrial chain and supply chain,and forming a dynamic balance of higher quality and higher level of economic development.
