It’s transformation of enterprise market belief type and the internal mechanism of influencing innovation investment fluctuation that is revealed under particular field pressure by extended dynamic evolution analysis method of the Brock & Hommes's adaptive belief system and parameterized the heterogeneous beliefs and field pressure of the enterprise, and then the conditions and characteristics of the fluctuation are simulated. The study found that field pressure and consensus, which enterprises are or not satisfied with the available resources after responding to the field pressure, is the key factor to affect the investment decision of ecological innovation. the stronger the organization field pressure, the more easy to realize the sustainable and stable development of the ecological innovation investment system, and switching non-innovation input to innovation input not only generate a smaller initial impact but also makes the time to converge to equilibrium earlier.
