Regional green development level and its spatial spillover effects: Empirical evidence from Hubei Province, China

•A regional green development index system is established based on the “driver-pressure-state-impact-response” model.•The level of regional green development in Hubei, China, is rising, and the gap between regions is narrowing.•The inter-regional spillover effect of green development is greater than the intra-regional spillover effect.•Technological innovation and the living environment have a positive spillover effect on green development. Green development strives to harmonize economic and social development with environmental protection. It is an innovative development model for people to follow in response to global climate change. This paper first combines the “driver-pressure-state-impact-response” (DPSIR) model with the entropy weighting method to measure the level of green development in Hubei Province from 2010 to 2018. Then, the spatial Durbin model (SDM) is used to analyse in depth the spatiotemporal evolutionary pattern and spatial spillover effects. The results indicate that after 2014, the levels of green development increased significantly and that regional differences gradually shrank. ρ = 0.409 indicates that the green development level has a positive spatial spillover effect, and the spillover effect between regions is greater than that within a region. The spatial spillover effects of the industrial structure and growth efficiency are −2.17 and −8.64, respectively, while the spatial spillover effects of technological innovation and the living environment are 7.35 and 0.32, respectively. Based on our findings, we provide several policy recommendations for developing countries to achieve green, coordinated and sustainable development.
