With the in-depth promotion of the “Belt and Road” strategy, intelligent technology has become an important support for the optimal allocation of regional economic resources. Digital technology has become a factor of production, and the construction of “digital bridge” in regional cooperation improves the efficiency of resource allocation. This study explores the mechanism and implementation effect of the integration of regional economic resource optimization and smart technology under the background of “Belt and Road”. By constructing a stochastic DEA model with non-expected output, we analyze the regional economic resource allocation efficiency from the input-output perspective by taking the logistics industry of 17 provinces along the “Belt and Road” as the research object from 2013 to 2019. The results show that Liaoning, Shanghai and Zhejiang provinces have maintained a comprehensive technical efficiency value of 1.000 for seven consecutive years, which is located in the production frontier; the average value of the comprehensive efficiency of Heilongjiang, Qinghai and Xinjiang provinces and regions is lower than 0.5, which is far lower than the average value of the industry of 0.685; the kernel density analysis reveals that the operational efficiency of the logistics industry of the provinces along the route evolved from a single-peak distribution to a bimodal distribution from 2013 to 2019, and the phenomenon of efficiency polarization has expanded. Expansion. The study identifies input redundancy and output insufficiency problems in each province by measuring the relaxation factor, and proposes an optimal allocation scheme of regional economic resources based on intelligent technology. The study concludes that smart technology can effectively enhance the efficiency of regional economic resource allocation, weaken geospatial constraints through digital platforms, improve information transparency and flow efficiency, reduce the risk of information asymmetry, and promote the leapfrog development of regional economic cooperation.
