This paper studied the disparities o f regional R&D Industry development from input and output.The main conclusions are as follows.The disparities of input amounts and input index among regions are distinct a nd very big.The activity structure of r egional R&D industry input are basic ally experiment development,appli ed re-search and basic research.All regio ns attach great importance to input t o experiment development.The enterprises are the main executing institutions of regional R&D industry input,next are R&D institutions or universitie s.The major part of outputs of regional R&D industry are from the eastern region s.However,the input -output ratio o f the middle regions are higher than th e eastern regions or the western regions,and regions with smaller inputs have higher input -output ratio.
