摘 要:我国高技术产业下属的电子及通信设备制造业发展迅猛,占高技术产业总量的比重高达55.95%,是我国高技术产业的主导产业,占据举足轻重的地位。文章以电子及通信设备制造业为例,采取系统聚类方法将30个省(西藏数据缺失将其剔除)电子及通讯设备制造业按人均指标分成发达省区、中等发达省区、欠发达省区,以此引入反映区域差异的虚拟变量,采用扩展的Cobb-Douglas生产函数模型对我国电子及通讯设备制造业省区差异与经济绩效进行回归分析。因地制宜的制定相关政策促进电子及通信设备制造业快速发展,缩小省区之间的差异。

Abstract: The manufacture of electronic equipment and communication(MEECE)is developing rapidly and accounting for the proportion of high-tech industry as high as 55.95%. It is China's high-tech industry's leading industries and occupies a pivotal position. In this paper, it takes the MEECE as an example. The 30 provinces of MEECE are divided into developed provinces, medium developed provinces, less developed provinces by the system clustering method. This paper introduces the virtual variables reflecting the regional differences, and uses the extended Cobb-Douglas production function model to analyze the regional provincial differences and economic performance of China's MEECE. According to local conditions to develop relevant policies to promote the rapid development of electronic and communications equipment manufacturing industry, narrowing the differences between provinces.
Key words: the manufacture of electronic equipment and communication; provincial differences; system clustering; economic performance

我国高技术产业是一个新兴的、发展迅速的产业,在国民经济中占据重要地位,推动我国经济由“投资驱动”向“技术驱动”转变,其高附加值与高收益的特点也代表着未来产业的发展方向。但从宏观层面和世界范围来看,我国高技术产业仍然处于起步发展阶段,同时我国高技术产业发展存在地域资源分布不均匀、区域差异明显等问题。
我国高技术产业下属的电子及通信设备制造业发展尤为迅猛,产业总值从1995年的2 052.78亿元(GDP总量60 793.73亿元,占比3.38%)增长到2015年的78 309.93亿元(GDP总量689 052.12亿元,占比11.36%),年均增长率达到19.97%。2015年高技术产业产值为139 968.64亿元,其中电子及通信设备制造业产值所占比重高达55.95%,是我国高技术产业的主导产业,占据举足轻重的地位[1]。……
