Green　development　has　become　an　essential　approach　to　overcoming　environmental　constraints　along　with　the　new　urbanization　process　in　China.　The　objective　of　this　study　is　to　explore　the　interrelationship　and　coordination　between　new　urbanization　and　green　development　across　30　provinces　in　China　from　2005　to　2020　utilizing　the　global　entropy,　coupling　coordination　degree,　and　panel　vector　autoregression　models.　Results　revealed　that　China　has　experienced　high　speed　growth　rates　of　new　urbanization　and　green　development　with　1.568　and　0.716　times,　respectively.　The　coupling　coordination　degree　between　new　urbanization　and　green　development　demonstrates　an　overall　increasing　trend　with　large　heterogeneity　among　each　province;　its　spatial　pattern　shows　a　decreasing　trend　from　east　(0.744)　to　west　region　(0.639)　in　2020.　From　the　viewpoints　of　interaction　between　the　two　indicators,　new　urbanization　hinders　green　development　in　the　early　periods　(except　for　the　eastern　region),　and　its　influence　disappears　as　the　number　of　periods　increases.　Overall,　a　positive　interaction　between　new　urbanization　and　green　development　exits,　but　the　coupling　coordination　degree　exhibits　a　strong　imbalance　across　Chinese　provinces.　Especially,　36.67%　of　provinces　which　is　concentrated　in　the　western　and　northeastern　regions　remain　insufficiency　and　imbalance　in　the　coupling　coordination　degree.　Policymakers　should　ensure　coupled　coordination　between　new　urbanization　and　green　development　and　address　interregional　disparities.　The　results　of　this　study　can　facilitate　Chinese　provinces　or　other　developing　countries　in　formulating　policies　and　actions　to　achieve　sustainable　development　through　coordinated　efforts　in　new　urbanization　construction　and　green　development.
