2000年以来长春市工业结构优化分析

Study on optimization of the industrial structure in Changchun city since 2000

工业结构优化是振兴东北老工业基地的关键.测度工业结构的高度化和合理化状态可作为评估东北老工业基地振兴绩效的依据.本文运用信息熵对长春市33个工业行业的高度化进行测评.结果显示,长春市目前形成了以交通运输设备制造业和农副食品加工业为两大支柱,以通信制造业、医药制造业、非金属矿物制品业、电力和热力的生产和供应业以及食品制造业为主要支撑的工业行业体系.通过比较劳动生产率对长春市工业结构的合理化进行估算,发现长春市的工业结构整体上趋于合理,但是行业之间不均等现象仍然很严重.最后从提升优势产业、改造传统产业和培育新兴产业3个方面探讨长春市工业结构优化升级的对策.

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.
