东北国有大规模企业数量过多,民营中小企业比重较低;企业“大而全”、“小而全”现象严重,产业分工协作不够,条块分割,行业竞争力不足。本文提出深化分工,拆分大企业生产链条,通过分层外包、出售、合资、租赁、合作等方式,形成分工协作,构建区域分工网络,并对东北加工制造业分工协作网络建设提出具体建议。 The number of state-owned large-scale enterprises in Northeast China is too large, and the proportion of small and medium-sized private enterprises is relatively low. The enterprises are “large and complete” and “small and complete”, with serious industrial division and cooperation, fragmented industries and insufficient industrial competitiveness. This paper proposes deepening the division of labor and splitting the production chain of large enterprises. Through such methods as stratified outsourcing, sales, joint ventures, leasing and cooperation, a division of labor and cooperation are formed, a regional division of labor network is established, and concrete proposals are made for the construction of division of labor and cooperation networks in Northeast Processing and Manufacturing Industries.
