For algebro-geometric study of J-stability, a variant of K-stability, we prove a decomposition formula of non-archimedean J-energy of n-dimensional varieties into n-dimensional intersection numbers rather than (n+1) -dimensional ones, and show the equivalence of slope JH- (semi) stability and JH- (semi) stability for surfaces when H is pseudoeffective. Among other applications, we also give a purely algebro-geometric proof of a uniform K-stability of minimal surfaces due to 23, and provides examples which are J-stable (resp. , K-stable) but not uniformly J-stable (resp. , uniformly K-stable).
