Abstract: China’s direct investment(COFDI) in BRIC countries has risen rapidly since 2005. It’s beneficial to promote China’s investment through studying the relationship between COFDI and investment environment in BRIC countries. Measuring the ability of introducing and utilizing investment in BRIC countries by calculating the COFDI performance index, the paper selected 26 indications from political, economic, social, technological and educational aspects to evaluate the investment environment by entropy weight method. The scores reflect the level of investment environment. Finally, a coupling and coordinative model between COFDI and investment environment is established, which could be used to explore spatio-temporal evolution of the coupling and coordinative discipline. The result shows that the coupling difference in BRIC countries was small, and Russia had the highest coupling degree, which was called medium rankings, and other countries are inferior, which fluctuated between lower and medium associations. The difference of coordinative degree was evident. The best was South Africa that could reach to primary coordination even superior coordination, Russia was fluctuated between the brink of imbalance to coordination, Brazil and India are basically lagging behind other countries which are always maladjusted. The study provide the enlightenment and reference for China to further invest in BRIC countries.
