基于对北京市居民生活用水户访谈与问卷调查,对北京市的东城、西城、朝阳、海淀、丰台、石景山6个区的居民生活用水户的水价支付意愿进行抽样调查,采用Logistic回归模型分析供水服务满意程度、家庭对水费负担程度、对北京缺水的认知程度、对现行水价态度等影响居民水价支付意愿的主要因素,结果显示:26.6%的被调查户愿意支付比现行水价高的水价,73.4%的调查户不愿意支付比现行水价高的水价。分析表明:用户对供水服务态度满意度越高、水费占家庭收入比重越低、对北京市缺水现状了解越多,则居民的水价支付意愿就越强烈。建议根据影响因素分析结果区分不同的目标支付群体,制定完善的水价调整政策,加大宣传力度并加强对低收入人群的水价补贴工作,从而提高居民支付意愿。 相似文献

农户意愿灌溉水价影响因素的实证分析——以内蒙古河套灌区为例 总被引:1,自引:0,他引:1
本文运用生产函数模型、面板数据模型以及排序选择模型,对农户意愿灌溉水价的影响因素进行了实证分析。结果表明:灌溉费用投入在农业生产中起着重要的作用;农户的蔬菜种植比重、玉米种植比重和小麦的种植比重越大,农户意愿灌溉水价越低;在灌溉水价提高时如果农户选择调整作物结构或选择节水,农户意愿灌溉水价就越高。农户实际灌溉水价与农户意愿灌溉水价产生巨大差距的原因在于该流域的实际灌溉水价的变动幅度较小。 相似文献

基于农户视角的生活供水状况改善支付意愿的实证分析——以江苏省镇江市为例 总被引:1,自引:0,他引:1
农村居民饮水现状不容乐观,改善农村生活供水状况,不仅有利于保障农户饮水安全,而且对于降低消费风险有益.基于城乡统筹的要求,镇江市将集中供水覆盖到周边乡镇,了解实际的连接意愿和支付意愿情况,有利于识别项目社会风险.本文采用条件估值法(CVM),对镇江市周边四个乡镇未来受益农户进行了供水需求的随机抽样调查,计算出农户对供水改善的户均支付意愿(WTP),并使用统计分析工具对WTP和可能对其产生影响的潜在因素进行了相关分析,可供制定水价时参考. 相似文献

Analyzing the demand for a new product that is not on the market presents challenges as agricultural producers search for potential value-added products and develop marketing strategies for these products. This study examines the market potential for a new pure blueberry sweetener in Kentucky. The results from a contingent choice survey indicate that the average respondent was not willing to pay a significantly positive amount for the product. However, a small group of respondents, who can be identified by their overall blueberry purchasing intentions and age, was willing to pay a price higher than the product's cost of production. Small and medium-size producers who are often limited by the financial and technical constraints associated with actual market trials of new products are likely to find that the type of marketing research described here is a particularly cost-effective method of getting information to assess market potential. 相似文献

水产养殖生态系统为人类提供了巨大的生态服务价值,但也造成一定程度的环境污染。本文利用CVM方法调查了淀山湖区域居民对水产养殖系统环境损害成本的支付意愿。分析结果表明,只有23.5%的居民对解决水产养殖造成的淀山湖生态环境损害存在支付意愿。利用单边界两分式问卷调查发现,对于水产养殖生态系统的环境污染治理的平均支付意愿为15.92元/人·年。据此计算,淀山湖周边三镇水产养殖系统的环境损害成本为每年276.7万元。居民治理水产养殖环境污染的支付意愿受收入、性别等社会经济因素的影响。 相似文献

Genetically Modified Crops, Corporate Pricing Strategies, and Farmers' Adoption: The Case of Bt Cotton in Argentina 总被引:1,自引:0,他引:1
This article analyzes adoption and impacts of Bt cotton in Argentina against the background of monopoly pricing. Based on survey data, it is shown that the technology significantly reduces insecticide applications and increases yields; however, these advantages are curbed by the high price charged for genetically modified seeds. Using the contingent valuation method, it is shown that farmers' average willingness to pay is less than half the actual technology price. A lower price would not only increase benefits for growers, but could also multiply company profits, thus, resulting in a Pareto improvement. Implications of the sub-optimal pricing strategy are discussed. 相似文献

森林环境资源价值评估是实施生态效益补偿和绿色GDP核算的重要基础,对其进行科学合理的定价,将加快推动森林资源纳入环境经济一体化核算工作的进程。条件价值法(CVM)作为森林环境资源价值评估的一种直接方法,对于评估"非市场化产品或服务"的价值,特别是森林环境资源的社会价值具有重要意义。考虑到该类非使用价值的分量众多,实际核算时应先进行系统分类,然后逐一加以测算。本文正是在此基础上,通过森林环境资源的供求分析,采用开放式支付卡法作为CVM的引导技术,对武夷山自然保护区居民消费意愿进行实地调查,并结合Logistic模型、因子分析确定社会价值的具体构成。最后,根据非参数估计方法计算个人支付意愿,从而极大提高了研究结果的有效性。 相似文献

We investigate consumer demand for genetically modified (GM) rice in urban China, using a relatively large survey of urban consumers in 2013 and the contingent valuation method. Our results show that respondents discount their WTP for first, second and third generation of GM rice by 31%, 34% and 36%, respectively, compared with non‐GM rice, indicating substantial aversion to GM rice by Chinese consumers. The level of consumers’ subjective knowledge of GM rice has a significantly negative impact on their WTP for GM rice, implying that GM rice in China has become a ‘special food’ with an unreliable image. 相似文献

In the analysis of stated preferences studies, it is often assumed that protesting is a discretely measured item only occurring among those who are not willing to pay. However, various studies have recently shown that protest beliefs are as well held by respondents who state a positive willingness to pay (WTP). Using latent class (LC) models, we investigate the extent of heterogeneity with respect to protest beliefs among all respondents of two contingent valuation studies. The advantage of LC models is that classes of individuals are endogenously identified and no selection bias is introduced by ad hoc definitions of protesters. Further we investigate whether it is possible to identify a class of non‐protesters. Finding a group of pure non‐protesters could indicate how strongly stated WTP in the whole sample is affected by protest beliefs. For both samples, we find a class with strong protest beliefs but no pure non‐protest class. Overall, our results suggest that LC models might not be the first choice to determine unbiased WTP measures, but they provide valuable insights into the degree of protesting expressed by different groups and corresponding determinants of group membership. 相似文献

Economic values of biological collections in three Australian botanic gardens in Canberra, Melbourne and Sydney were estimated using the travel‐cost method (TCM) and the contingent valuation method (CVM). The TCM component of the study produced average per‐trip consumer surplus (CS) values of $39 and $18 for single‐ and multiple‐site visitors, respectively, for each botanic garden, resulting in an estimate of approximately $194 million for the total social welfare generated by trips to the three sites. Marginal willingness to pay (WTP) for access to botanic gardens was also investigated through payment vehicles of entry fees or higher parking charges using the CVM component. The analysis revealed a positive mean WTP of between $3 and $5 per trip per person. The difference between the CVM and TCM results reflect the different underlying concepts of value under investigation: average CS per visit for the TCM and the utility arising from a marginal visit for the CVM. Marginal changes in CS from the TCM were derived. The confidence intervals from the TCM marginal values overlap the WTP estimates from the CVM. These findings will be useful for resource management decisions in the botanic gardens collection in Australia. 相似文献

This stated preferences survey determines the willingness to pay (WTP) for climate change mitigation policies using a representative sample of the German population. WTP is compared across three valuation question formats in a split sample design: the dichotomous choice (DC) referendum, the dissonance minimizing (DM) referendum and the two‐way payment ladder (TWPL). The influence of multinational cooperation on WTP is assessed by variation in the hypothetical scenarios. We demonstrate that the DM referendum and the TWPL, two question formats that induce similar response incentives, yield equal mean WTPs. Multinational cooperation did not change WTP in any of the question formats. Implications for current contingent valuation practice are discussed. 相似文献
