Managers and researchers can make timely adaptation policy to improve and innovate economic, cultural and environmental performance to impulse the green growth. The study used the methods such as the multiple criteria analysis, analytic hierarchy process, principal component analysis, and the grey theory model to build and integrate green growth indicators into the green growth index. The green growth index was developed by 9 subjects and 18 indicators. The data of study were collected a period of seven years from 2009 to 2015. The results of study indicated that almost districts increased the green growth index. District 1 and District 5 reached at high green growth level about 60 score, while others were classified into average green growth level. The results of green growth prediction of districts in Ho Chi Minh City also showed that the green growth index will lightly increase from 2016 – 2020.
