Does Public Data Openness Promote Urban Green Innovation Cooperation? Evidence from China

Introduction

As cities face mounting pressure to achieve economic growth while reducing environmental impact, green innovation has become a central pillar of sustainable urban development. At the same time, governments around the world are increasingly embracing public data openness as a tool to enhance transparency, efficiency, and innovation. But an important question remains: can opening public data actually promote cooperation in urban green innovation?

Drawing on evidence from China, this post explores how public data openness influences collaboration among cities in developing green technologies and sustainable solutions.

Why Public Data Openness Matters

Public data openness refers to the free and accessible release of government-held data, including information on environmental quality, energy use, transportation, and industrial activity. When such data is openly shared, it reduces information asymmetry and lowers coordination costs among firms, research institutions, and local governments.

In the context of green innovation, open data enables cities to:

• Share knowledge on environmental challenges and best practices

• Identify complementary technological strengths across regions

• Coordinate investments in green research and development

• Avoid duplication and improve innovation efficiency

Urban Green Innovation Cooperation

Urban green innovation cooperation involves collaborative activities such as joint research projects, co-patenting, technology transfer, and cross-city environmental initiatives. Unlike isolated innovation, cooperation allows cities to pool resources and expertise, which is especially important for complex green technologies that require long-term investment and interdisciplinary knowledge.

China provides a valuable case for studying this relationship due to its rapid digital governance reforms, expanding open data platforms, and strong policy emphasis on green development.

Evidence from China

Empirical evidence from Chinese cities shows that higher levels of public data openness are associated with stronger green innovation cooperation networks. Cities with more transparent and accessible data environments tend to engage more actively in inter-city collaboration, particularly in areas such as clean energy, pollution control, and low-carbon technologies.

The findings suggest that public data openness works through several channels:

• Enhancing knowledge diffusion across cities

• Strengthening trust and coordination among innovation actors

• Supporting data-driven decision-making in environmental policy

• Amplifying the spillover effects of green innovation

These effects are especially pronounced in regions with stronger digital infrastructure and higher innovation capacity.

Policy Implications

The results offer important insights for policymakers. Simply investing in green innovation is not enough; creating an open and data-rich governance environment is equally crucial. Governments can strengthen urban green innovation cooperation by:

• Expanding the scope and quality of open government data

• Improving data standardization and interoperability across cities

• Integrating open data initiatives with green development strategies

• Encouraging public–private partnerships based on shared data resources

Conclusion

Public data openness is more than a transparency tool—it is a powerful enabler of collaborative green innovation. Evidence from China shows that when cities open their data, they create fertile ground for cooperation, accelerating the transition toward sustainable and environmentally friendly urban development.

As cities worldwide pursue green transformation, embracing data openness may be a key step toward building smarter, greener, and more cooperative urban futures.
