Study on China's Eco-innovation Performance Based on the Comparison with Three Northeastern Provinces

This paper constructs the indicator system for evaluating eco-innovation, and studies the eco-innovation performance of 30 provinces in China in 2009 by the factor analysis method, and makes a comparison analysis with the situation of three northeastern provinces. The result shows: innovative strength, technical environment and the degree of environment protection are the key factors influencing eco-innovation performance, the innovative strength of Liaoning province is the greatest in three northeastern provinces, but it's at greater expense of environment; Heilongjiang Province has better environment for technology development, but innovative strength is weak; Jilin province has no advantage in these three factors.
