摘　　要：以北京市空气污染健康危害经济评价为例，采用目前国际上推荐的条件价值评估最适合的二分式问卷格式，探索条件价值评估最大支付意愿引导技术在我国应用的适用性．结果表明，单边界问卷格式和双边界问卷格式估计平均最大支付意愿分别为739．57，652．33元，年．两闯卷格式估计平均最大支付意愿的95％置信区间分别为656．49～845．34，604．04-707．01元，年．双边界问卷格式与单边界问卷格式相比能够获得被调查者支付意愿的更多信息，从而缩小估计的置信区间，提高最大支付意愿的估计精度．The applicability of technique applied in China to induce the greatest willingness to pay of contingent valuation was explored, using economic appraising of health harm by air pollution of Beijing City as example, and adopting the most suitable dichotomous choice format of contingent valuation recommenced internationally at present. The annual mean willingness to pay of single bounded and double bounded estimation were 739.57, 652.33Yuan/a, respectively. Furthermore, the 95% confidence interval of annual mean willingness to pay estimated by the two questionnaire formats were 656.49-845.34, 604.04-707.01Yuan/a, respectively. Double bounded model compared with the single bounded model could obtain much more information of willingness to pay of the person investigated, thus reducing confidence interval of estimation, and enhancing the estimating accuracy of the greatest willingness to pay.
