Measuring the recreational value of world heritage sites is a key issue in the heritage tourism. This paper employs Contingent Valuation Method (CVM), which is an evaluation instrument on the basis of tourists′ attitude and preference, to measure the recreational value of Jiuzhaigou, one of the World Natural Heritage sites in China, and analyzes the biases in the survey. The results show that: 1) In 2009, Jiuzhaigou′s recreational value was 3.46×108 yuan (RMB), and the per capita Willingness to Pay (WTP) was 137.31 yuan by CVM. Compared with the results of other methods, this result is significantly low. 2) Among the factors that influence Jiuzhaigou tourists′ WTP, psychological perception factors have the greatest effect while demographic and socio-economic characteristics have a small effect on WTP. 3) The virtuality in CVM creates biases both from CVM itself and in the procedures that CVM was implemented. The former includes hypothetical bias, information bias, protest response bias, and strategic bias; and the latter includes the questionnaire design, population and sample definition, sampling and data processing. The paper analyses those biases and illustrates their potential in-fluences on the accuracy of CVM measurement. 4) Although there are various defects in CVM measurement, it is still an effective valuation method. 展开更多

Background: Around 2000 plant species occur naturally in Lorestan Province of which 250 species are medicinal and myrtle is one of them. Myrtle is a shrub whose leaves and fruits have medicinal value and thus, if managed and harvested properly, could produce sustained economic benefits. In recent years, however, over half of the myrtle site areas was destroyed, due to inappropriate management and excessive harvesting practices. Thus, coming up with a practical harvesting approach along with identifying those factors damaging the sites, seems to be very crucial. Methods: In our investigation, we calculated the conservation value per hectare of myrtle in the Dooreh forest area in Lorestan Province. Using the Contingent Valuation (CV) and Double Bounded Dichotomous Choice (DBDC) methods, we determined the willingness to pay (VVTP) for myrtle conservation. The VVTP was estimated with a Iogit model for which indices were obtained based on a maximum precision criterion. Results: The results showed that 86.67 per cent of people were willing to pay for the conservation of these myrtle sites. Average monthly WTP per family was calculated as $0.79. The annual conservation value in terms of WTP for the preservation of the myrtle sites in Dooreh was estimated as $102,525. Among the variables of the model presented, education had a positive impact, while the amount proposed for payment and family size had a negative impact on the WTP. Conclusions: Our estimate of the value of myrtle conservation should provide justification for policy makers and decision making bodies of natural resources to implement policies in order to conserve the natural sites of this species more effectively. 展开更多

The contingent valuation method (CVM) is one of the main methods for evaluating non-market values of resources. It originated in the United States and was introduced into China during the 1980s and 1990s. However, application of CVM in China is highly controversial based on three primary aspects: (I) the appropriate guidelines for CVM; (2) the elicitation techniques for willingness to pay (WTP); and (3) reliability and validity testing of CVM. The major objectives of this paper are to i^eview the recem devel- opments pertaining to guidelines, elicitation techniques, and reliability and validity testing for application of CVM, and to summa- rize the limitations of and measures for improving application of CVM in China. The applicability of CVM in China is discussed to enhance the future development of CVM in China. 展开更多

The In most contingent valuation (CV) studies, WTP (Willingness to pay) and WTA (Willingness to accept) were often used separately, so protesting or no response or even babbling answers are increasing, and the debate persists over the reliability of CV in economic policy analysis. In order to improve the reliability of CV, WTP and WTA is used syn-chronously to estimate the restoration cost of Maqu grassland ecosystem. Data were partly from questionnaire survey, and partly from interviews and authorities. Before conclusions were derived, we assumed these data that came from interviews and authorities were right. The main result is: If we assumed that the degraded grassland of Maqu needs 10 years to be restored, and divided the restoring period into two stages, then the restoration cost was 0.85 × 108 RMB per year in former 4 years, 0.022 × 108 RMB per year in latter 6 years. The total cost of Maqu grassland restoration was 3.62 × 108 RMB. For all the costs of restoration, WTA occupied 94% and WTP only occupied 6%, suggesting that local grassland degradation was mainly caused by overgrazing and that the overloading livestock must be eliminated in order to achieve restoration successfully. Our research also showed that combining WTP and WTA in contingent valuation is very useful in estimating the cost of environmental improvement projects. Of course, whether these results are right or not, further researches are needed in the future, especially for the actual number of livestock in Maqu grassland. 展开更多

The purpose of this study is to provide an evaluation of the possible criteria used by the people of Thessaloniki for the evaluation of public goods and the investigation of the benefits of the conservation and restoration of city structures affected by carbon monoxide. These benefits are expressed in monetary units by using the CVM (Contingent Valuation Method). The maintenance of the urban environment often entails excessive costs paid by the people through taxation. A city free of aesthetic pollution results in an increase in tourism. A portion of taxation paid by the citizens is allocated to cleaning the city. An increase in tourism provides the government with additional revenue through VAT (Value Added Taxes). The main findings show that in a large proportion, 28% of the interviewees are willing to pay, but those that are willing to pay significant amounts tend to prefer mild interventions to the buildings, while those (42%) that agree with minimal to null amount demand radical intervention. The latter group, also, considers any contribution of theirs to restoration as unfair, judging that this expenditure should be covered exclusively by the State. Last but not least, from a sociopsychological point of view, this attitude could be attributed to extreme personalities which tend to prefer more holistic and direct solutions (i.e., no mixed strategy involving people and the State is acceptable by interviewees who considered themselves as having no further obligations after regular tax-paying); as a result, they think that the State is exclusively responsible to resolve the situation. 展开更多

The subject of this study, which involves two surveys, is to estimate externalities created round a cultural heritage preservation site by means of a CVM (Contingent Valuation Method). The first survey was conducted for the ruins of ancient "Diolkos" located in Isthmus of Corinth, Greece using a sample of 200 soldiers. The second survey was conducted for the ancient theater of Lefkada, using a sample of 100 tourists mad locals. The results have been analyzed with Logit model regression. The findings show that willingness to pay (or participate) is strongly affected by opportunity cost and awareness of the site's history. Further, income level and education level play a critical role in developing volunteering activity. 展开更多

The Contingent Valuation Method is used to evaluate individual preferences for a change concerning a public non-market resource or property. The objective is to build a nonparametric forecasting model of an individual's Willingness To Pay according to geographical location. Within this framework, an estimator (of type Nadaraya-Watson) is proposed for the regression of the variable related to geolocation. The specific characteristics of the location variable lead us to a more general regression model than the traditional models. Results are established for convergence of our estimator. 展开更多

The value of a statistical life(VSL)is a crucial tool for monetizing health impacts.To explore the VSL in China,this study examines people’s willingness to pay(WTP)to reduce death risk from air pollution in six representative cities in China based on face-to-face contingent valuation interviews(n=3936)from March 7,2019 to September 30,2019.The results reveal that the WTP varied from CNY 455 to 763 in 2019(USD 66-111),corresponding to a VSL range of CNY 3.79-6.36 million(USD 549395-921940).The VSL in China in 2019 is estimated to be CNY 4.76 million(USD 689659).The statistics indicate that monthly expenditure levels,environmental concerns,risk attitudes,and assumed market acceptance,which have seldom been dis‐cussed in previous studies,significantly impact WTP and VSL.These findings will serve as a reference for ana‐lyzing mortality risk reduction benefits in future research and for policymaking. 展开更多

[Objective] This study was to analyze the personal Willingness to Pay (WI-P) on the non-use value of Dianchi lake wetland and the influential factors. [Method] Questionnaire was designed according to the Contingent Valuation Method (CVM) to investigate people of different occupations at different ages, based on which the evaluation on non-use value of Dianchi lake wetland was carried out. And the relationship between WTP and social characteristics were analyzed by using non- parametric estimation. [Result] The average WTP on Dianchi lake wetland is 150.03- 217.66 yuan per person every year, and the total WTP is 626-909 million yuan ev- ery year. Age, education and residence of the respondents have remarkable influ- ence on the VVTP. The influence of education level and residence on option value is significant; bequest value is significantly correlated with age; while there is no significant relationship between existence value and social characteristics. [Conclusion] The evaluation on the non-use value of Dianchi lake wetland is important for the scientific development and utilization of wetland resources. 展开更多

By using Contingent Value Method(CVM),WTP(Willingness to Pay) of wildlife in Jinggangshan Nature Reserve was studied,the overall existence value of wildlife resource(namely the sum of economic,social,ecological value added on its existence value) in this area was calculated,and the statistics of primary social and economic factors affecting payment value were analyzed.600 questionnaires had been issued altogether and the recovery rate was 100%,583 of which were valid and the effective rate was 94.2 % which demonstrated that feedback sample quantity had reached the analysis requirement.The study result showed that interviewees with different social characteristics widely dispersed,which complied with the survey principle of random sampling;that the distribution curve of WTP was neither smooth nor normal and as 50 Yuan was frequently-used amount in their daily consumption,people tended to choose this option subconsciously;that WTP had notable correlation with education degree,monthly income and cognition degree,and had relation with age but no obvious relation with gender;that annual payment value per capita was within the research scope of wildlife payment value,that is 40-575 Yuan/(person·year).The final conclusion was that wildlife resource value in this area was 17 845 000 Yuan/year,which was of great significance to the protection of biological diversity and the formulation of corresponding protective measures in Jinggangshan Nature Reserve and even in the whole society. 展开更多

The“social contract”is the most famous philosophical text of Zac Jacques Roussos,which was to influence the intellectual and political movement of the 18th century.By publishing the“social contract”or“Civil Law Principles”in 1762,Rousseau,presenting his theory of the state and seeking the foundation of civil society,attempts to expose the conditions of a stable and just state by putting freedom as a precondition for law and the common good must be lawful.A central place in its political theory is the concept of general will,which is in the general interest(otherwise the common good)and on which the idea of a favored constitutional state is based.We estimate approximately the size of the external economy by the method of the Contingent Valuation Method(CVM).The Contingent Valuation Method(CVM)is a survey-based technique,frequently used in Experimental Economics,especially useful for the valuation of non-market resources/goods/services,and cultural heritage objects(of aesthetic,historic,scientific,or social value),such as conservation of monumental remains and preservation of the physical and anthropogenic environment. 展开更多

The preservation/restoration of natural environment is usually entailing high cost mostly paid by citizens through taxes.The effect of these taxes is double. The direct effect is the obvious additional income for the State, and the indirect effect is anadditional income for the citizen, due to increasing tourism. Since the evaluation of this good cannot be in market terms, authorsapply a modified CVM (Contingent Valuation Method), which is part of Experimental Economics, in order to find out the order ofconcern that people have about natural environment. Authors also, try to investigate their WTP (Willingness To Pay) for supportingactivities for preservation/restoration of three lakes in Northern Greece, in particular, lake of Ioannina, lake of Florina and lake ofKastoria. For the purpose of this research, authors use parametric and non-parametric approaches, as well as Linear Regression andLogic Models. 展开更多
