Abstract: China's economy has shifted from rapid growth to quality growth. It is a national strategy to push quality growth of Yangtze River economic zone, which is powered by scientific finance. This paper establishes a comprehensive evaluation index system of scientific finance and quality economic development, which is measured by means of entropy weighting and chronological overall factors. Taking quality economic development as dependent variable and scientific finance development index as covariant, this paper uses sole factor covariance to analyze the quality economic development of 9 provinces and 2 cities along Yangtze river economic zone during 2007 to 2017, and reveals that its scientific finance development is higher in down-stream than middle- to up-stream. Quality economic development varies largely among the economic zone, less if not considering the impacts of scientific finance, which is a critical factor in influencing quality economic development in 9 provinces and 2 cities along Yangtze river economic zone. This paper presents suggestions on focusing on combination of scientific industry and financial institutes, balancing scientific finance resources so as to diminish the provincial quality economic development variance.
