Ecological civilization is an important symbol of social civilization and an important part of economy, politics, culture and society. This paper uses the index data of the "Bulletin of 2017 Annual Evaluation Result of Ecological Civilization Construction in Zhejiang Province" to study the spatial pattern of green development indicators and six sub-dimensional indicators, and to explore the impact of spatial correlation on ecological civilization construction in Zhejiang Province. The results show that:(1) The differences between the green development indexes and sub-dimension indexes of different cities in Zhejiang are obvious. Hangzhou has the highest green development index, while Jiaxing's green development index is at the lowest level. (2) There is spatial autocorrelation in the green development index, but the Global Moran's I is not high. However, in the sub-dimension index, there are obvious spatial autocorrelations in environmental governance, environmental quality, ecological protection, growth quality and green life except resource utilization. (3) There is a flow of capital, talents, and technology among the developed counties, and there is sufficient economic strength and technology to invest in environmental pollution control and prevention, and ecological environment restoration and protection, forming a green development diffusion and spillover area. However, the unsustainable development mode of the undeveloped counties at the cost of resources and environment has obvious constraints on improving green development indicators, showing a polarization effect and a low-speed growth trend. (4) It is considered that the spatial correlation can play a leading role in the construction of ecological civilization among counties, and to improve the overall level of ecological civilization construction. On the one hand, we need to build a cross-regional green development cooperation mechanism and implement a cross-regional ecological compensation mechanism; on the other hand, we should give full play to the leading role of pilot and demonstration to produce positive externality spillover effect.
