In this paper, ecological footprint methods were used to calculate the ecological footprint of six cities （Nanchang, Jingdezhen, Jiujiang, Xinyu, Yingtan and Fuzhou） in the Poyang Lake Area, Jiangxi, China from 1991 to 2010. Ecological footprint was the input factor for ecological resources and the contribution of this and other factors such as labor and capital to economic growth were analyzed. The results showed that, from 1991 to 2010, ecological footprints in the six cities increased year by year. The amount of land for fossil energy, under cultivation and grassland influenced total ecological footprint in each city. The contribution of ecological resources, labor factors and capital factors to economic growth showed regional differences. Nanchang, Jiujiang, Xinyu, and Yingtan are capital-orientated and capital factor had a great influence on the economic growth rates, whereas, Jingdezhen and Fuzhou were labor-orientated. The contribution of ecological resources to economic growth in the six cities was the lowest of all three factors, meaning that efficiency of ecological resource utilization is low. Total productivity plays a key role in economic development; however, the overall level of total factor productivity for the six cities was low and indicates that the technological content of Poyang Lake Area’s economic growth is low and the utilization of input factors extensive. In summary, we suggest changing the mode of economic growth and developing tertiary industry in the region.

This paper addresses the problem of macroeconomic effects of consumptive government expenditure and volatility on economic growth. Firstly, a stochastic endogenous growth model of consumptive government expenditure is presented, which is more general to reflect the reality in contrast to the neoclassical deterministic growth model. Then based on stochastic dynamical optimization method, the macroeconomic equilibrium and equilibrium solutions is derived. Finally, the macroeconomic effects of consumptive government expenditure and stochastic disturbance on economic growth are analyzed, and the optimal size of consumptive government expenditure is derived.

关键词： Consumptive government expenditure stochastic dynamical optimization endogenous economic growth Bellman equation macroeconomic equilibrium.
