高技术产业演化的时空分异测度研究

The measurement on the space-time differentiation of high-tech industry evolution

利用信息熵、集中度指数和产业空间集聚β指数等指标对中国高技术产业演化的时空分异状况进行测度,计算结果表明:在时间序列上我国高技术产业演化可以分为三个阶段,演化特征呈现"均衡→非均衡→均衡"格局。在空间布局上我国高技术产业呈现较强的地理集中现象,且高技术产业地理集中存在地方性行业垄断特征,不同行业集中趋势不同,主要集中在长江三角洲、珠江三角洲和环渤海湾三大地区。高技术产业分工的地方化特征是导致高技术产业布局与空间距离具有弱相关性的直接原因。

The evolution situation in time and spatial series of Chinese high -tech industry is measured by the information entropy, the concentration degree index and index. The conclusion indicates that the high -tech industry evolution can be divided into three stages in the time series, the evolved characteristic presents ＂balance -unbalance - balance＂ pattern. High -tech industry of China takes on strong geography concentration phenomenon in the spatial distribution, at the meanwhile the industry geography concentration shows local profession monopoly characteristic. Further more the different industry concentration tendency is different. The main concentration areas include Yangtze River Delta, Zhujiang Delta and Bohai Rim. The localization characteristic of distribution is the efficient amse, which leades to the weak relevant between the high - tech industrial layout and the space length.
