: The age structure of a population will affect the labor force sustainability,
which ultimately affects the economic sustainability of a country. This study aims to
develop a model for assessing the labor force sustainability in terms of population
ageing and its impacts on economic sustainability in different industries and the
national economy. This model is based on a computable general equilibrium
(CGE) mechanism that consists of three components: (1) forecast of labor supply;
(2) forecast of labor demand; and (3) assessment of the impacts of labor market
imbalance (shortage) on the macroeconomy. The results of the economic forecast
of China prove that this model can effectively assess the impacts of labor market
imbalance on economically sustainable development. Furthermore, a simulation
forecast of China from 2014 to 2030 was performed. The results show that the
contributions of most of China’s industries to the gross domestic product (GDP)
show a negative growth trend. From the medium- and long-term points of view,
the influence of population ageing to the labor-intensive industries is the most
serious. The construction industry’s contribution to GDP growth rate still shows
a rising trend, but the growth rate decreases annually. The service industry’s
contribution to GDP growth rate shows a significant upward trend, but the rate is
decreasing annually. Economic growth shows a declining trend. Population ageing
has little influence on consumption and investment, but in absolute numbers, the
GDPs growth rate is lower in scenarios that consider population ageing than in
scenarios that do not. The pulling effect of exports to economic growth will continue
to decrease.
