“The Residents’ Income Increase Index” is the first of five second-class subsystems in “The Measuring System of People’s Living Development Index of China”，and it is important component of oppositely unattached “The Evaluation System of People’s Living Consumption Demand Status of China”. Based on the fiducial 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，Ningxia，Yunnan，Henan and Inner Mongolia ranked top five. The lateral measurement based on no-gap ideal value in 2016 shows the gap still exists because of the poor coordination and balance；Beijing，Shanghai，Zhejiang，Shandong and Liaoning ranked top five. If the countrywide residents’ income data should synchronously achieve a minimum ratio of the urban and rural until the bridging of the urban and rural ratio，the people’s living standards development index would be significantly enhanced.
