Abstract:Sustainable development for the economy and society depends on the scale and level of enterprises’ green tech-innovation. In the current economic system, the dual externality of production activities has direct impacts on the insufficient driving force for the green innovation. Game relations among stakeholders of green tech-innovation are deeply analyzed. Various factors to constrain firms’ green tech-innovation are discussed. And from four aspects, respectively, government regulations mechanism, industrial intermediary organization supervision and evaluation mechanism, consumption reversal drawing mechanism and customers’ participation mechanism are proposed, which can also offer helpful references for constructing green innovative economies.
