“The Residents’ Income Increase Index” is the first of five subsystems at second-class in “The Development Index System of People’s Living Conditions of China”. Based on the cardinality value since 2000，the longitudinal measurement shows a largest rise in the people’s livelihood index of the West，followed by the Central Regions，the Northeast and the East，which means some preliminary effects of the national strategy of regional balanced development. Shaanxi，Henan，Ningxia，Inner Mongolia and Anhui ranked top five. The ideal no-gap lateral measurement in 2015 shows that the gap exists because of the poor coordination and balance. Shanghai，Beijing，Liaoning，Zhejiang and Tianjin ranked top five. If the countrywide residents’ income synchronously should achieve a minimum ratio of the urban and rural until the bridging of the urban and rural，the people’s living standards development index would be significantly enhanced.
