摘要: 本文定量分析2017—2020年长江经济带绿色创新发展的现状、成就及影响机制,运用经济学“投入—产出”分析框架,以城市为对象,从八个维度评估长江经济带绿色创新发展水平,并实证检验绿色创新投入对产出的促进作用。研究发现:长江经济带110个城市的绿色创新发展水平呈现整体上升趋势;不同维度的绿色创新投入具有显著不同的绿色创新产出效应,其中创新制度的促进作用最大;地方财政增加创新制度宣传、科研投入支出,可有效强化创新制度和研发投入对绿色创新产出的促进效应;保持创新制度和研发投入的稳定性是取得产出促进效应的关键。本文丰富了绿色创新发展的应用研究,为推动长江经济带绿色创新发展提供了新的思路和有益启示。

Abstract: This paper quantitatively analyzes the current situation,achievements,and impact mechanisms of green innovation development in the Yangtze River Economic Belt from 2017 to 2020 Using the economic“inputoutput”analysis framework,the study takes cities as the object and evaluates the level of green innovation development in the Yangtze River Economic Belt from eight dimensions,and empirically tests the promoting effect of green innovation inputs on outputs The research finds that the level of green innovation development in the 110 cities along the Yangtze River Economic Belt shows an overall upward trend Green innovation inputs in different dimensions have significantly different effects on green innovation outputs,and the promotion of innovation systems has the greatest effect Increasing local financial support for innovation system promotion and research and development expenditure can effectively enhance the promoting effect of innovation system and R&D investment on green innovation outputs,and maintaining the stability of innovation systems and R&D investment is the key to achieving output promotion effects This study deepens and enriches the application research of green innovation development and provides new ideas and helpful insights for promoting green innovation development in the Yangtze River Economic Belt
