Exploiting the construction of Public Resource Trading Centers across cities as a quasi-natural experiment, this paper investigates the impact of market-oriented allocation of public resources on the digital transformation of enterprises. The research finds that the market-oriented allocation of public resources produces better market incentive effect and resource guidance effect, which makes enterprises have stronger internal motivation and resource base to implement digital transformation. Further research finds that the above effects are more pronounced in the regions with high dependence on public resources, outstanding government digital construction and enterprises with strong internal incentives.
