Abstract: The first time we defined the term of Gold Purchased by GDP (GPG) and regarded it as a new indicator of economic growth. GPG means the gold weight purchased by GDP according to the annual average exchange price and the annual average international gold price. Exploring the relationship between natural resource consumption and economic growth will contribute to improve the efficiency of resource utilization. This paper analyzed the data of commercial timber harvested, population, GDP and GPG of Southwest China since 1949, tested the hypothesis of Resource Curse and Kuznets Curve, the results showed: 1) with the increasing of GDP by 422 times from 1952 to 2008, the population, GPG and commercial timber harvested grew by one times, 4.5 times and 12 times respectively; 2) the commercial timber decreased by 80% resulted from the Natural Forests Protected Program from 1997 to 2000, but the figure of 9.5 million m3 in 2008 reached the level of 1997 and its increasing trend has not been changed since 1949; 3) the economic development experienced three GPG platforms and it stood at the third one currently. The linear correlation between GPG and timber consumption in the first 20 years was significant (P<0.01); 4) the per capita GPG increased by 1.5 times with the per capita GDP growing by 162 times. The linear correlation between commercial timber consumption and population was significant (P<0.01). The nonparametric correlation between GPG and population was true (P=0.005). The Resource Curse and Kuznets Curve did not exist between timber consumption and per capita GDP or per capita GPG; and 5) the commercial timber consumption per 10 thousand yuan or per kilogram GPG appeared inversed U-shaped curve, and the economic growth went through the period which has promoted by intensive labor and timber consumption.

Key words: timber, GDP, Gold Purchased by GDP (GPG), economic growth, Southwest China
