- W2367586476 abstract "From the perspective of quantity protection,this paper,taking the Pearl River Delta as the case study area,evaluates the performance of cultivated land protection policies in China's mega-city regions from 1992 to 2008,by constructing dummy variable model and applying method of autoregression analysis.The results indicate that the variables of the polices are not statistically significant even at the 15% level;while variables of proportion of secondary and tertiary industry added value to GDP and agricultural product price index are significant at the of 5%,10% respectively,and all have a negative relationship with dependent variable.It is concluded that compared with the average national conditions,effect of reducing farmland conversion is not significant in the Pearl River Delta,but dependence on land input of non-agricultural economy is declining,and that the rising of farm product price also makes for the stimulation of the self-employed farmers' enthusiasm for protecting cultivated land.The paper holds that cultivated land protection in mega-city regions should be turned to a comprehensive perspective of ecological,food,economic and social security,rather than single food security view." @default.
