High - tech indusries, now playing a Leading role in the national economy, have become a major e- conomic force to drive the rapid economic development of China. According to the cerresponding index which reflected the development of high - tech industries, the temporal evolution of high - tech industry growth of Jian- gsu province was studied via using the hierarchical clustering method with the city and the economic zone as basic units. The results showed that high - tech industry development characteristics of Jiangsu exhibited a very high growth rate. The industrial scale was stepped diminishing from the southern to northern part. At the same time, the industrial development speed stepped increasing from southern to northern part. The industry structure differences are significant. The fastest growing industry was aerospace manufacturing, and the new material manufacturing takes the largest share.
