摘要
基于四川省工业投入产出数据,构筑产业发展能力指标体系,根据类内相似,类间差异原则对71个工业部门进行系统聚类,基于箱线图,描述各类型特征;利用熵值法划分产业类型对各指标分别赋予权重,以保证所有产业同一指标因类型差异而拥有不同权重.最后计算各产业发展能力综合得分值,选择建筑业、煤炭开采和洗选业等前11位产业为四川省主导产业.
Taking Sichuan province for example,we have developed an industrial development ability index system basing on input-output data.According to the principle of differences between categories and category similarity,by employing Ward＇s method and Euclidean distance,we classified 71 industrial sectors into six types and described the features of each type by using boxplot diagram.By employing the entropy method,we determined weight to each index of each type to ensure that the same index of all types of industries has different weight as different types.At last,we calculated the total score each industry could obtain in terms of their development potential and 11 industries emerged as the leading industries of Sichuan province.
