摘要:

耕地保护的外部性显著,探析不同样本方案下基于单边界二分式CVM的耕地保护外部性差异性及其影响因素,有利于科学测度耕地保护经济补偿标准。本文以焦作市为例,分别测度了均分样本、非均分样本和分类非均分样本三种不同方案下耕地保护外部性,明晰了样本分类与合并、投标值样本数量及其均衡性对耕地保护外部性测度结果有效性与精度的影响。结果表明:①结合案例比较,在科学设置投标值和假想市场、合理进行假想偏差规避以及合适样本数量下,本研究中均分样本、非均分样本方案测度结果具有较高的有效性,可确定为现实条件下耕地保护经济补偿下限,即耕地保护最低经济补偿标准。②以非均分样本方案测度结果为基准,均分样本和分类非均分样本方案下测度结果的偏差值分别为41.5元和255.5元,偏差率则分别为3.2%和19.5%。因此基于单边界二分式CVM测度结果与投标值样本数量显著相关,与投标值样本数量均衡度的相关性则不显著。③在进行二分式CVM样本方案设计和实施时,均分样本、非均分样本、分类非均分样本方案均可采用,但各投标值(包括分类样本)最低样本数量需达到30份以上,其测度结果才具有较高的有效性。④在实践上,应基于最低耕地保护经济补偿标准,结合区域经济社会发展水平以及资金来源等条件,建立区域耕地保护经济补偿标准动态提升机制,完善耕地保护经济补偿体系。

Abstract:

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.
