能源煤化工基地产业链评价与优化对策

Evaluation and Optimization of the Industry Chains in Energy and Coal Chemical Industry Bases

在能源煤化工基地工业系统分析的基础上,提出延伸产业链、拓宽生态位,及加强产业链耦合等产业链优化技术途径,并选取宁东能源煤化工基地进行典型案例分析。利用企业间关联度和废弃物资源化率两项指标对宁东能源煤化工基地的食物链(网)进行分析评价。分析得出,宁东能源煤化工基地的企业间总关联度为0.378,表明基地内各工业种群间联系较紧密,产业链结构基本合理;固体废物资源化率为10.69%,废水资源化率为9.91%,表明基地内固体废物及废水资源均未得到充分利用。据此提出开展重点技术研发、发展补链型产业、建立企业联盟等宁东能源煤化工基地产业链优化对策。

Based on the analysis of the industrial system of energy and coal chemical industry bases （ECCIBs） , several optimization approaches were developed, such as extending the industry chains, broadening the ecologic niches, and strengthening the industry chain coupling. Ningdong ECCIB was selected to be the typical base for further analysis. The food chains （nets） of the base was analyzed and evaluated by the connectance between the enterprises and the waste recycling rate. It was concluded that the total connectance of Ningdong ECCIB was 0. 378, which meant closer links existing between the industrial populations in the base, and the industry chains were basically reasonable. The solid waste recycling rate of Ningdong ECCIB was 10. 69% , while the wastewater recycling rate was 9.91%, which meant that the solid wastes and the wastewater were not well reused. Accordingly, several optimization approaches were proposed for the Ningdong ECCIB, including carrying out the key technology research, developing complement chain-type industries, and establishing the enterprise alliances.
