摘要
供给侧结构性改革要求提升供给体系的关联性和创新力,省域作为国内大循环承上启下的关键层次,需形成结构合理、协调通畅的产业供给网络.利用河南省最近两期投入产出数据和SNA方法,对省域产业供给网络进行定量研究,分析网络内前向关联及位于网络中心、边缘位置的典型产业,揭示省域经济循环供给层面的总体概貌.研究发现,首先,中间品部门和最终品部门分别发挥直接前向关联和间接前向关联作用,对经济体系产生不同影响;其次,服务业部门在省域经济循环中的地位凸显;最后,河南省产业供给网络的内部关联性日趋紧密,融入省内、国内经济大循环的程度进一步提升.
Abstract
Supply-side structural reform requires enhancing the relevance and innovation of the supply system.As a key level of the domestic large cycle,provinces need to form a reasonable and coordinated industrial supply network.Using the latest two in-put-output data and SNA method of Henan Province,this paper quantitatively studies the provincial industrial supply network,analyzes the typical industries with forward linkages and located in the center and edge of the network,and reveals the overall picture of provincial economic cycle at the supply level.The study finds that,first,intermediate goods sectors and final goods sectors play,respectively,different roles in direct and indirect forward linkages,and have different impacts on the economic system;second,service sectors stand out in the provincial economic cycle;third,the internal linkages of Henan Province's in-dustrial supply network become closer,and its degree of integration into provincial and national economic cycles is further en-hanced.
