| Popis: | To explore the impact of new urbanization development on industrial water utilization efficiency, the epsilon-based measure model and the entropy method were used to calculate the industrial water utilization efficiency and the development of new urbanization based on the panel data of 30 provincial cities in China from 2011 to 2020. Then the spatial Durbin and the panel threshold models were constructed to explore the spatial spillover and threshold effects of new urbanization development on industrial water utilization efficiency. The results show that there are large regional differences in the development of new urbanization and industrial water utilization efficiency. New urbanization development has a positive spillover effects on the improvement of industrial water efficiency. The promotion effect of new urbanization development on industrial water efficiency is affected by the level of new urbanization development, thus showing different results. According to the findings, it is recommended that local governments at all levels should increase their efforts to build new urbanization. And boost high-level and high-quality development of towns and cities while promoting the rationalization of industrial structure and optimizing resource allocation, thereby improving the efficiency of industrial water utilization. HIGHLIGHTS The evaluation index system is constructed from five dimensions to analyze the differences in the development of new urbanization.; Using industrial wastewater discharge as unexpected output, the epsilon-based measure model is used to calculate the industrial water efficiency.; The analysis of the dynamic development by kernel density estimation.; The spatial Durbin and threshold models are used to analyze spatial spillover and nonlinear effects.; |
