我国高技术产业的空间聚集现象研究——基于省际高技术产业产值的空间计量分析

A study on the spatial distribution of Chinese hi-tech industries——spatial econometrics analysis based on province-level industrial output value

以高技术产业规模以上企业产值(当年价)作为衡量各省区高技术产业发展水平的指标,研究我国高技术产业的空间分布特征。通过对各省区1995-2004年高技术产业产值的Theil熵和相对增长速度的计算,指出我国高技术产业发展水平的不平衡性逐渐加剧,高技术产业呈现出在少数几个省区聚集的现象。Moran指数I及Moran散点图揭示出我国高技术产业的发展水平及其增长模式都存在着明显的全局和局域空间依赖特征;并通过对2004年高技术产业产值的回归分析,进一步检验和计算空间相关性的作用强度。

Spatial distribution features of Chinese hi- tech industries are studied based on output value at current prices of industrial enterprises above designated size across provinces. Theil entropy and relative growth of output value show that the inequality of the development of the hi - tech industries among provinces increased from 1995 to 2004 and that they concentrate in several provinces. Moran＇ s I index and scatter plot indicate that there are significant global and local spatial autocorrelation in industrial output value and its growth model. At last, regression results of the industrial output value of 2004 prove the existence of spatial autocorrelation again and its coefficient is given out.
