Abstract: Green development is popular in protecting the Yangtze river, which is backed by synergy innovation. This paper selects panel data of 11 provinces along Yangtze river economic zone during 2009-2017, and uses compound synergy model and SBM to measure their synergy innovation ability and green development level of the 11 provinces. Results show that, as time goes by, their synergy innovative ability remains little change, but outstanding in geographic distribution, highest in the down-stream. The green development level is rising, not high generally with variance among provinces, relatively higher in Shanghai and Jiangsu in down-stream. Both strongly show a regional difference at the same pace. This paper applies panel Tobit model to study the impacts of government-customer-industry-institute synergy innovation ability on green development and concludes that this synergy innovation can improve green development, as clearly shown from middle- to down-stream, but not from up-stream.
