中文摘要：

信息产业作为新兴产业的主导力量对区域产业结构升级的影响深远。笔者基于主导产业理论分析电子信息产业发展推动区域产业结构合理化的作用机制。在信息产业发展和区域产业结构合理化评价指标体系的构建基础上，运用灰色关联理论测算了电子信息产业发展与区域产业结构合理化的关联程度。研究结果表明，东、中、西部的电子信息产业发展水平与区域产业结构合理化之间存在较大的关联。其中，东、中部地区信息产业发展主要通过提升区域产业技术进步速度推动区域产业结构合理化，而西部地区产业结构合理化的动力来自于电子信息产业的总量扩张而非内涵发展。

英文摘要：

Information industry as the dominant core of emerging industry has far-reaching impact on regional industrial structure upgrading. From the perspective of rationalization, based on the theory of leading industries, this paper analyzes the mechanism of electronic information industry development to promote regional industrial structure rationalization. Constructing the index system of information industry development and regional industrial structure rationalization, this paper uses grey correlation theory to measure the degree of association between electronic information industry development and regional industrial structure rationalization. The results show that there is a big correlation between electronic information industry development of the eastern, central and western and regional industrial structure rationalization. Information industry development of the eastern and central promotes regional industrial structure rationaliza- tion mainly through technological progress rate, while regional industrial structure rationalization of the western is driven by the scale expansion hut not connotation develonment of the electronic information industrv.
