Harmonizing to Choong-Ki Lee and Sang Yoel Han ( 2002 ) in their survey, “ Estimating the usage and saving values of national Parkss ‘ touristry resources utilizing a contingent rating method ” found that this survey gauge the benefit and preservation value for five national park in Korea with utilizing dichotomy pick method to gauge the value. Apart from that, the consequence from this survey can demo the sum of nature touristry degree.

Contingent Valuation Method ( CVM ) gauging the usage value which is include consumer excess and benefit from diversion activities and non usage value is conservation plan. In this contingent rating survey, they utilizing dichotomy pick to gauge willingness to pay from the respondent. There are three method to measure willingness to pay value, the first method is minimal monetary value willing to pay which evaluate scope between nothing to a?z . Second method is overall monetary value that willing to pay which evaluate scope between -a?z to +a?z , and 3rd method is cropped monetary value willingness to pay which evaluate scope between nothing to maximal command.

Apart from that, this survey cover five national park in Korea there are Mt. Soraksan, Mt. Pukhansan, Mt. Kayasan, Hallyo-Haesang and Taean-Haean. Total questionnaire issued in this survey every bit much as 2300, which 530 questionnaire from Mt. Soraksan national park, 550 questionnaire from Mt. Pukansan, 400 questionnaire from Mt. Kayasan, 420 questionnaire from Hallyo-Haean and 400 questionnaire from Taean-Haean. Therefore, questionnaire signifier divided to four parts, portion step the diversion ingestion and preservation value, rejection and attractive factors and state of affairs of the environment and demographic portion.

Consequence in this survey show that the beauty natural beginning and the distance travelled influenced straight on the usage value. Therefore, cost and travel clip disbursement determine tourers in make determination on gauging usage value. The usage value of the national park has positive relationship with the distance travelled. While preservation value of the national park has positive relationship with the distance travelled for visitant and non visitant. Society put high preservation value if their abode is nearby national park. At the same clip, appraisal of those use value for all national park were more higher compared to capture fees and keeping cost. Therefore, those appraisal value is utile for enterpriser to better the quality of the environment and diversion installation with addition the entryway fees.

Harmonizing to Nandini Hadker, Sudhir Sharma, Ashish David, T.R. Muraleedharan ( 1996 ) , their survey discuss about willingness to pay to keep and conserve Borivli National Park ( BNP ) by utilizing CVM. The intent of this survey is to gauge usage and non usage value on the nature ‘s installation and society public assistance from BNP preservation plan and proof the cogency from this construct.

CVM applied in this survey to mensurate the value of the natural resources in Borivli National Park ( BNP ) . They used Interview Schedule ( IS ) in this survey. The intent of used IS is to distinguish multiple dichotomy command such as low income respondent Rs5-10-15, average income Rs20-30-40 and high income Rs45-60-75. Total questionnaire for contingent rating is about 500 to 600 respondent. The sampling point for questionnaire is country Bombay metropolis. At the same clip, questionnaire signifier divided to four parts. First portion is answering background, 2nd portion about respondent ‘s sentiment and respond to the environmental development issue and their willingness to pay to continue and conserve BNP, 3rd portion discuss about the BNP job and the 4th was the issue on contingent rating.

Consequence of their survey discuss that India promote continue development plan if the preservation and saving cost were low. Apart from that, instruction degree of answering influence straight of the willingness to pay, the degree willingness to pay high if their instruction degree is high. Therefore, they found that the high value of the BNP the high degree of the willingness to pay of the respondent. Although India is developing state with medium and depression of the mean income, but society in India still willing to pay for nature ‘s installation preservation purpose around BNP.


Harmonizing Thomas Broberg dan Runar Brannlung ( 2007 ) on their survey “ On the value of big marauders in Sweden: A regional graded contingent rating analysis ” discuss about saving and furthering carnival animate being in Sweden. The aim in this survey is to gauge willingness to pay of single for maintain and continue four species of carnival in Sweden by utilizing CVM.

There are around 24 inquiry in their questionnaire set including 2 willingness to pay inquiry. Apart from that, inquiry about socio-economic respondent besides be ask in their questionnaire. Consequence from their survey demo the minimal monetary value willingness to pay from the entire respondent is around SEK236. Therefore, different location record different willingness to pay of each respondent which willingness to pay at Stockholm more higher than Wolf-territories. It is because respondent unrecorded nearby species carnival will willing to pay higher comparison to others. Hence, minimal willingness to pay in this instance show prejudice. Therefore, they hard to gauge right that willingness to accept is zero. Apart from that, the consequence from this survey show that societal value or societal cost in set up ordinance carnival is negative. Hence, respondent will take higher monetary value willingness to pay when they face lack information about that topographic point.


Harmonizing E.J. Sattout, S.N. Talhouk dan P.D.S. Caligari ( 2006 ) , in their diary “ Economic value of cedar relics in Lebanon: An application of contingent rating method for preservation ” carried out in Lebanon forest which rich with biodiversity resources and home ground for several species that have economic potency to Lebanon. This survey develop three aims where foremost nonsubjective is about the difference value of the forest among urban and the villager, among user and non user of the forest. Second nonsubjective place the best option to roll up fund and place other utile alternate to develop schemes in preservation plan intent. Third nonsubjective refer consequence of the survey as usher for farther survey probe. The intent they apply CVM is to reexamine about population cognition and to roll up willingness to pay for preservation wood activities at Lebanon. This method can increase forest surface and advance the of import of preservation Lebanon forest plan to society and future coevals.

The utile of arrested development is to gauge the value of WTP which can demo the relationship between WTP and variables socio-demography of the respondent. They make questionnaire survey in three urban countries in Lebanon viz. Tripoli, Sidon and Beirut metropolis and besides two forest modesty country in Lebanon. Apart from that, sample size that they taken is about 0.01 per centum from entire population in Lebanon. Where around 328 respondents that taken from three major metropoliss and 123 respondents from the small town about. Harmonizing to the consequence of the survey, willingness to pay for forest user and non user around US $ 20 per family for both urban and rural country. Hence, frequence to acquire zero value willingness to pay is from the non forest user respondents. Through the consequence can promote authorities to develop public assistance bureaus and centralise the fees aggregation for diversion installations at forest Lebanon.

Harmonizing to.Y. Jim dan Wendy Y. Chen ( 2004 ) in their diary entitled “ Recreation – agreeableness usage and contingent rating of urban greenspaces in Guangzhou, China ” found that their research point focal point at 235.5 km2 from Guangzhou, north Pearl River Delta. Their survey discuss about chance and diversion installations were of import factor to nature based consumer which all this resource supply by green universe metropolis Guangzhou. They besides carry out nonsubjective for step chances and diversion installations and besides to gauge value of the ingestion utilizing Contingent Valuation Method ( CVM ) in their research survey. In apply CVM, duality and pay card method attack will be used. The intent of wage card method provide counsel to respondents to find monetary value willingness to pay ( WTP ) . They besides found that there have failings of apply wage card method system there are possibility would cut down appraisal for the merchandise and environment service they used.

Apart from that, questionnaire signifier divided to four portion. First portion were related with the intent of the survey and definition about green universe Guangzhou and diversion activities which respondents can more understand during answer the inquiry from the questionnaire set. Second portion are request diversion experience and diversion activities of the respondents. Third subdivision are step willingness to pay for green universe metropolis. While last portion is talk about socioeconomic information of the respondents. At the same clip, the intent they use pilot survey is to do dependability trial of the inquiry whether respondents can understand the inquiry or non. Therefore, around 340 respondents been taken and interviewed in this survey. Range age of the respondents that taken is between 18 to 70 old ages old and this questionnaire survey carried out around Guangzhou metropolis.

The consequence of this survey found that 96.6 per centum from the entire respondents were willing to pay to see green universe metropolis. This instance demo that good quality of diversion and healthy activities can pull more visitant go to see and take this topographic point to make full their free clip. They found that WTP for single for visit to green universe around RMB17.40 per month ( US $ 1=RMB8.26 ) where are more higher than payment of entryway fee. Apart from that, the value WTP are influenced by income degree and fringy consequence. Therefore, green universe sum value achieve RMB54.7 million per twelvemonth where sixfold higher comparison to Guangzhou yearly expenditure for green universe metropolis. This consequence can assist to analysis the cost and benefit when demand high on resources for green universe metropolis development and direction.


Harmonizing to Maria Reynisdottir, Haiyan Song dan Jerome Agrusa ( 2008 ) in their survey entitled “ Willingness to pay entryway fees to natural attractive forces: An Icelandic instance survey “ take portion at natural country Iceland and this survey discuss about entryway fees to natural resource country can forestall inadequacy public fund for preservation and direction natural resource country intent.

Therefore, they done their questionnaire one twenty-four hours on working twenty-four hours and one twenty-four hours on weekends. Questionnaire signifier designed to several linguistic communications include English linguistic communication, Icelandic linguistic communication and German linguistic communication. Respondent besides been asked the maximal sum they willing to pay to see that park. It is because direction done non enforce any entryway fees to Gullfoss or Skaftafell, so the intent of WTP from respondent is to conserve and better and forestall environment harm. The consequence of this survey show that around 92 per centum from the entire respondents is willing to pay the entryway fees. Hence, it show that entire and population consumer excess per season at Gullfoss around ISK333 and ISK41 million. Therefore entire and population consumer excess per season at Skaftafell around ISK508 and ISK 34 million. Apart from that, entire WTP each person is different because of the differences in footings of income, attitude on environmental issues, entire visit, abode topographic point. Age and instruction degree.

Harmonizing to Monica Ilijia Ojeda, Alex S. Mayer dan Barry D. Solomon ( 2007 ) in their survey entitled “ Economic rating of environmental services sustained by H2O flows in the Yaqui River Delta ” been done at Yaqui River Delta. This survey discuss about economic value from nature installations around Yaqui River Delta, Sonora, Mexico which harmonizing to measuring of WTP person from local occupant for bing nature installations or H2O flow keeping at Yaqui River.

This survey discuss about measuring non market attack where this attack divided to two classs viz. pick revealed method and pick province method. Revealed method is a survey on entire travel cost while pick province attack is combination of experiences experiment and contingent rating. A study contingent rating for 40 villager at Delta City, Ciudad Obregon are being managed to gauge non market value on flow ingestion. Respondents given scenario and Delta Hypothesis and besides step willingness to pay on H2O purchase.

The consequence of this survey show that around 148 respondents were willing to pay every bit much as 75 pesos per month. From this survey, they found that willingness to pay single influence by independent variables there are include income degree, instruction degree, figure of household members and beforehand sum offer. This consequence enable determination shaper to compare the benefit that can be enjoyed or produced which are refer to the H2O ingestion. Apart from that, the purpose consequence of this survey is to pull off deficiency of H2O supply in keeping H2O resource attack in long term.

Harmonizing to Serge Garcia, Patrice Harou, Claire Montagne dan Anne Stenger ( 2008 ) in their research entitled “ Models for sample choice prejudice in contingent rating: Application to forest biodiversity ” and research take portion at country France forest which two format they used in their contingent rating inquiry to print willingness to pay value for maintain biodiversity in the France forest. They besides develop two aims in this survey. First aim is to measure recreational activity in Gallic forest country by utilizing travel cost attack and sketch the differentiate between chief country in France. Second aim is to measure biodiversity in France forest with apply contingent rating analysis.

Application of contingent rating attack in this survey is to print WTP value where utilizing Dichotomy Choice ( DC ) method and Open ended ( OE ) inquiry. DC attack reincarnated to accommodate inquiry in assorted province. Apart from that, two econometric theoretical account been used in this research context there are Probit theoretical account and Tibit theoretical account. Probit theoretical account is for DC inquiry while Tibit theoretical account is for OE inquiry. This research take portion in whole state with utilizing phone interview. Respondents sample divided to two sub-sample there are single sub-sample which carried out recreational activities in forest country and single sub-sample that does non carried out recreational activities in forest country.

The consequence from this survey show that dichotomy pick was bias on WTP. They estimate that Probit theoretical account and pick sample both set up prejudice job in DC inquiry. Therefore, OE inquiry as a 2nd prejudice factor where as a nexus random for respondents which non willing to pay. Hence, average WTP from entire respondents every bit much as 11.59N” and this same with the criterion of the Probit theoretical account, every bit much as 30.35N” . therefore, for the OE inquiry, average WTP for visitant and non visitant are 39.84N” and 33.42N” .

2.6 Decision

With the being of past research usher, some research worker able connect earlier survey with survey that is being carried out. There are many inexplicit and expressed definition of preservation and saving and there are many ways to place contingent rating attack by different people or parties. Anyway, assorted benefits of preservation and saving acceptance have been identified. Researcher can besides be develop suggestion or technique and new thought that can be used in current survey. Therefore, past research as a mention for research worker for their related surveies field.
