Low-carbon city pilot and smart city pilot are two main measures which could improve urban land green use efficiency (ULGUE). We take two pilot policies as quasi-natural experiment. Using the difference-in-differences (DID) method, we designate "dual policy" cities as the treatment group to examine the combined effect of the policies on ULGUE. To our knowledge, this is the first attempt to integrate these two policies into a unified analytical framework. This framework allows us to investigate both their coordination effects and the magnitude of differences between dual and single policies. We find that (1) Both the low-carbon pilot or smart city pilot can improve the ULGUE. (2) Dual-pilot cities show a stronger enhancement of ULGUE than the single policy. (3) Policy sequence demonstrates varying effect magnitudes, suggesting that ecological regulation provides a solid foundation for subsequent technological upgrading.
