Green development cannot be achieved without innovation in green technology. Only when green technology is innovated can a country achieve high-quality development. Regarding the construction of ecological civilization as a quasi natural experiment, green patent data was used to empirically analyze the impact of ecological civilization construction on green technology innovation through the double difference method. It is found that the construction of ecological civilization significantly promotes green technology innovation in the experimental zone. Ecological civilization construction can attract environmental investment and human capital, and is conducive to infrastructure improvement and industrial structure upgrading, thereby promoting the level of green technology innovation.
