The quality difference of the exchange and cooperation on information in RIN is the main reason of the different innovation abilities of different RINs. In order to measure the intensity and coordination of the information exchange in RIN, according to the data stream analysis, the authors use the intensity and coordination of the fund flow between innovation units to reach the goal indirectly. And they design a conceptual model and index system which can comprehensively describe the intensity and coordination of information exchange in RIN .This model and index system can serve as a basis to make a further analysis and comparison of RINs athwartships or lengthways.
