In this paper, a GDP projection model was constructed based on the Cobb-Douglas production function and the Autoregressive Integrated Moving Average (ARIMA) model. Under the consideration of balanced development the Gini coefficient of provincial GDP per capita was used to measure the degree of development balance. This model projects Chinese provincial GDP and GDP per capita from 2016 to 2050. Based on the balanced development from technology, labor, and capital. The projection results show that from 2016 to 2050, the gap between the GDP and GDP per capita in each province will shrink and the Gini coefficient will decline. In this projection, the Gini coefficient will decrease from 0.219 in 2015 to 0.176 in 2030 and then to 0.137 in 2050. The results also show that development of each province will tend to be balanced in the future.
