Abstract:

The optimization of industrial structure is the key to the revitalization of the old industry base of Northeast China. Besides, it is the basis for assessing the performance to measure the sophistication and rationalization of the industrial structure. Using the method of information entropy, we measured the sophistication of 33 industrial sectors in Changchun. The results show that an industry system has been formed. In the system the transportation equipment manufacturing industry and agro-food processing industry are the pillar industries, and the communication manufacturing industry, pharmaceutical manufacturing industry, non-metallic mineral product industry, production and supply of electricity and heat, and food manufacturing industry are the main supporting industries. By using the method of comparative labor productivity, we estimated the rationalization of industrial structure in Changchun. The results show that the industrial structure trends towards rationality, but the inequality between the industries is still serious. Finally, we put forward suggestions for the optimization of industrial structure by enhancing competitive industries, reforming traditional industries, and cultivating new industries.

Key words: industrial structure, upgrading industry, information entropy, deviation analysis, Changchun city
