The cultivated land protection externalities are remarkable. To explore the difference and influencing factors of cultivated land protection externalities under different sample schemes based on the single-bounded dichotomous choice CVM,which is conducive to scientifically measure the economic compensation standard of cultivated land protection. Taking Jiaozuo as an example,to evaluate the cultivated land protection externalities of the average sample scheme,the non-average sample scheme and the classified non-average sample scheme. The effects of classification and merging of the samples,the number and the balance of samples on the validity and accuracy of the measure of the cultivated land protection externalities were clarified. The results show that:(1)Combined with the case comparison,the results are higher reliability of the average sample scheme and non-average sample scheme in the scientifically set the bid value and the hypothetical market situation,reasonably avoid bias and properly set the sample size,which is chosen as the lowest economic compensation standard of cultivated land protection under realistic conditions;(2)The result deviation of the average sample scheme and the non-average sample scheme are 41.5yuan and 255.5yuan respectively,the corresponding deviation rates are 3.2% and 19.5% respectively based on the result of the non-average sample scheme. Therefore,the results are significantly correlated with sample size of bid,and the correlation with equilibrium of sample size of the bid is not significant based on the single-bounded dichotomous choice CVM;(3)It is recommended to use the average sample scheme,the classified average sample scheme and the classified non-average sample scheme in the design and implementation of sample schemes of the dichotomous choice CVM. However,the measure result is highly reliable,which is only the minimum sample size of each bid value (including classified samples)is more than 30;(4)In practice,to establish and improve the dynamic promotion mechanism and system of cultivated land protection based on the lowest economic compensation standard of cultivated land protection.
