The industry categories are numerous in our country, and characteristics on sci-tech input and economic status of each industry are different each other. In this paper, eight pillar industries in Shaanxi province are regarded as examples. At first the empirical data about sci-tech input and economic status is statistically analyzed to study the differences on eight pillar industries. And the correlation between sci-tech input and economic status of eight pillar industries is studied. Moreover by means of cluster analysis, eight pillar industries will be divided into three categories according to their level of sci-tech input and economic status. Then the coordination between sci-tech input and economic status is analyzed on eight industries.
