The impact of government data accessibility on cross-regional venture capital investments

• The establishment of government data open platforms significantly boost cross-regional VC investments. • The positive impact is achieved through the reduction of information asymmetry . • The government's informatization and transparency initiatives can positively enhance the cross-regional flow of financial capital and foster economic development. This study examines the association between government data accessibility and venture capital (VC)'s cross-regional investments. Exploiting the staggered establishment of government data open platforms (GDOPs) across different cities in China as a positive shock to government data accessibility, we find that this policy significantly increases cross-regional VC investments in treatment cities relative to others. Furthermore, the positive impact is achieved through the reduction of information asymmetry , as the establishment of GDOPs attracts VC investments from greater geographical distances. Additionally, we find a more pronounced positive effect of GDOPs on promoting cross-regional VC investments in regions with higher terrain ruggedness and lower fiscal transparency. Overall, this study demonstrates that the government's informatization and transparency initiatives can positively influence financial markets by enhancing the cross-regional flow of financial capital.
