汶川地震后四川省工业产业结构变化研究

2008年的汶川地震给四川省工业企业带来了巨大损失，同时，也给调整和优化产业结构带来了契机。文章从工业行业的角度，分析了512汶川地震前后四川省工业的产业结构变化，主要探究工业的内部结构调整。研究基于四川省工业总产值数据，借鉴信息熵来度量四川省工业产业结构复杂程度和变化特征。运用均衡度和优势度指标进一步度量各行业之间分布的差别。研究结果按行业和按地级市分别展示四川省工业产业空间结构变化特征，并总结了灾后重建9年来存在的主要问题。最后，从提高工业基础和合理布局空间结构两个角度提出发展策略及方向。

INDUSTRIAL STRUCTURE CHANGE OF SICHUAN PROVINCE AFTER WENCHUAN EARTHQUAKE

The 2008 Wenchuan earthquake made huge damage to Sichuan's industrial enterprises, and also provided opportunity to adjust and optimize Sichuan's industrial structure. This paper analyzes the industrial structure change before and after Wenchuan 5 12 earthquake, and studies its internal structure adjustment based on Sichuan's GDP. This paper uses information entropy to measure the complexity and change of industrial structure in Sichuan, and further uses balance and dominance indicators to mark the difference among each industry. The results are displayed by sectors and by prefectures to show the spatial change of industrial structure in Sichuan province. This paper discusses the major issues in reconstruction since the earthquake and presents strategy from perspectives of improving industrial basis and planning spatial structure.
