公共数据开放与突破式绿色创新
Public Data Openness and Breakthrough Green Innovation
摘要
Abstract
Against the backdrop of the ongoing advancement of dual carbon goals and the deepening of green and low-carbon transformation,breakthrough green innovation has become a critical pathway for enhancing China's green competitive advantage.Given the high knowledge complexity,substantial research and development uncertainty,and elevated coordination costs inherent in green innovation,firms often struggle to achieve key technological breakthroughs with internal resources alone.Public data openness offers a potential solution to this challenge.As a key practice in digital government development and the value realization of data elements,the opening of urban public data platforms can provide firms with insights into green technology opportunities and support the exploration of novel innovation trajectories.This paper aims to evaluate the impact of public data openness on firms'breakthrough green innovation,reveal the potential value of data resources,and offer new strategic insights for firms pursuing high-quality development. This paper utilizes data from A-share listed companies in China from 2010 to 2023 and treats the opening of urban public data platforms as a quasi-natural experiment.A multi-period difference-in-differences model is employed to systematically examine the impact of public data openness on firms'breakthrough green innovation and the underlying mechanisms.The findings reveal that public data openness can promote firms'breakthrough green innovation.Mechanism tests indicate that this promoting effect operates through two main channels:increasing the depth of green knowledge search and fostering green collaborative innovation.Heterogeneity tests show that the positive effect is particularly pronounced for firms in the growth stage,firms embedded in global innovation networks,and firms located in cities with higher climate policy stability. The marginal contributions are as follows.First,by integrating forward and backward citations of firms'green patents,this paper constructs a measurement method for breakthrough green innovation based on the CD index,providing a quantitative tool to capture the extent to which firms'green technologies break from existing knowledge bases and technological trajectories.This approach offers a robust measure for micro-level research on breakthrough green innovation.Second,this paper systematically elucidates how public data openness empowers breakthrough green innovation by enhancing the depth of green knowledge search and promoting green collaborative innovation,providing empirical evidence of its positive effect.It also expands the boundaries of research on the economic consequences of public data openness and offers both theoretical insights and practical guidance for firms seeking to leverage public data to achieve high-quality green development.关键词
