The study of the relationship between trade and environment has always been a research hotspot in the field of national resource and environmental economics.Based on 963 papers in China National Knowledge Infrastructure(CNKI)with regard to the relationship between trade and environment,which were published from 1992 to 2019,the literatures were analyzed by using CiteSpace software with keyword co-occurrence map,keyword cluster analysis and keyword time zone map in order to summarize the dynamics,hotspots and frontier issues in the relationship between trade and environment.Research result shows that(1)International trade,environment,trade liberalization and environmental regulation were the hot issues in the study of relationship between trade and environment.(2)The number of literatures on the relationship between trade and environment has gradually changed from rapid growth to stable development.(3)Little cooperation was found between domestic authors and research institutions,so that regional cooperation teams for the research field have not been formed yet.(4)In recent years,although environmental regulation has gradually become a hotspot in the study of the relationship between trade and environment,the research is insufficient.
