Land use change is the most significant aspect in the research field of globe changing. Affected by both of natural and artificial factors, the land use and land resources quality varied continually. Dongguan City where the zone has a typical feature of land use change and significant ecological effects is selected as a case. This paper analyzed the spatial conversion of arable land in Dongguan city...
This paper studies how does the individual enterprise of the middle and large-sized enterprises clusters choose its own innovation strategy between independent innovation strategy and imitative innovation strategy and what effect does its choice have on itself and the whole society through evolutionary game theory. The conclusions reveal that on one hand, the government's most basic policy on encouraging...
Builds a state space model of energy consumption and economy growth, and uses Kalman filter algorithm to estimate parameters, and also, uses cointegration test to verify the reliability of the model. The results show that both the long-term and short-term elasticity of energy consumption experience significant fluctuation process from up to down. The same trend of fluctuations may explain that energy...
This paper analyzed the spatial pattern of cultivated land conversion in the Coastal Area of Pearl River Estuary based on RS and GIS technology. The results showed that the cultivated land area reduced rapidly under the pressure of urban expansion, and it was the main period about the cultivated land to reduce from 1988 to 1995. Other types of land also were converted to the cultivated land, which...
