Economic Growth and Agro-environmental Fragility——Based on the Provincial Panel Data Analysis

The agro-environmental fragility of 31 provinces and regions (except Hong Kong, Macao and Taiwan) of our country during the years 1978-2004 is measured by adopting the method of principal component analysis. With the support of analytical model of panel data, regressive analysis is achieved from the aspects of introducing regional differences, not introducing regional differences, existing industrial differences and not existing industrial differences respectively. The conclusion points out that there are both industrial and regional differences in the economic growth effect on the environmental fragility; these differences are reflected on the industrial or regional development levels. The higher the development level it is, the less the effect it is when the economic growth effect on the environmental fragility is negative, the more when the effect is positive, and it will change from being negative to positive when on the critical point; and vice versa.
