Abstract Based on the data of 92 prefecture-level cities in the Yellow River Basin from 2004 to 2018, this paper examines the interaction and spatial spillover effects of urbanization and eco-efficiency from the perspectives of population, land and industry by using spatial simultaneous equations, and further reveals the two-way impact of urbanization and eco-efficiency and the asymmetric relationship between different boundary areas. There results are as follow: While the urban ecological efficiency in the Yellow River Basin is gradually improving, the gap among cities is also expanding. And the population, land and industrial urbanization show a gradual increasing trend, and the development trend of industrial urbanization is more favorable; The impact of urbanization on ecological efficiency is positive, and the impact of urbanization on ecological efficiency in adjacent areas is negative, and decreases with the expansion of neighborhood distance; Ecological efficiency has a negative effect on urbanization as a whole, but the spillover effect of ecological efficiency is significantly different under different boundary neighborhoods. When the distance reaches more than 200 km, the spillover effect of ecological efficiency in adjacent areas on the urbanization of local population changes from negative to positive, and the negative effect on land urbanization weakens with the increase of distance. The impact on industrial urbanization shows a positive spillover effect within 200 km, and a negative effect beyond 200 km is gradually significant. Therefore, it is imperative to build a “local proximity” linkage effect within a reasonable regional scope to promote the improvement of ecological efficiency in the Yellow River Basin.
