Comparative Study Of Sanjiang Plain Wetland Willingness To Work And Economic Willingness To Pay

Report at 18 th National Congress, put forward "the five one", the social people from all walks of life pay more and more attention to the ecological civilization construction.Ecosystems provide material guarantee for the human production and living, is one of the most important support in the tourism and leisure, biological reproduction.Protect the ecological environment, keep the balance of nature is one of the basic human goals, it is also an important guarantee to maintain biodiversity and sustainability.Wetland ecosystem is undertake the transformation of terrestrial ecosystem and aquatic ecosystem area, has the advantage of water into soil, have the laudatory title of “kidney of the earth”, can not only storage water, regulating climate but also maintain biodiversity and sustainability.Sanjiang plain wetland as a key international wetland biodiversity areas, has been included in the list of international important wetland and its ecological and environmental protection value of the research is of important significance.Now the contingent valuation method(CVM) is widely used to evaluate the value of environmental services, the ecology resources, and the ecological environment items at home and abroad. The double bounded dichotomous was widely used in the CVM which is the most active format of contingent valuation method.But, compared the payment card with Dichotomous CVM, The latter process more complicated, the questionnaire data is just a point on the respondents utility function,not directly estimated the largest WTP,subsequent statistical analysis is the key to get the average willingness to pay.This paper takes the sanjiang plain wetland as the research object, on the basis of predecessors’ study.Further study of the sanjiang plain wetland ecological protection of the Willingness to Work(Willingness To Work, WTW), using the double bounded dichotomous method integration analysis the WTW data, finally fitting negative binomial regression model.The wetland value of monetization evaluation made it possible to wetland protection and development of the value of contrast, the results provide a reference basis for the decision of the relevant departments.The paper takes the sanjiang plain wetland protection value as the evaluation objects, through the questionnaire survey, issued 1302 interview questionnaires, 665 network questionnaires.Collected, 1197 questionnaires, among them, 1003 interview questionnaires was gotten, recovery rate is 77.0%; callback 194 network questionnaire, recovery rate is 29.2%.960 valid questionnaires after screening, of which 621 are pay questionnaire, 339 zero pay questionnaire, is paid at a rate of 64%.In effective questionnaire, the choice of labor of willingness to pay questionnaire 122, accounted for about 12.7%.This study analysis the questionnaire data which researched from the double bounded dichotomous parameters method,the calculated average WTP value respectively: considering the influence factors,The average WTP of the WTP function model was 126.37 Yuan per year, On the contrary,was 131.93 Yuan per year. Apply random utility model obtained the mean WTP was 133.04 Yuan per year.Survival analysis of weibull model, the average WTP is 126.04 yuan per year.Then the negative binomial regression model to calculate the average lower limit of willingness to work is 3.5 hours/per year.Application of the negative binomial regression model for sanjiang plain wetland protection value of total willingness to work was about 100 million yuan per year, total willingness to pay is 3.2056 billion yuan per year, total willingness to work is one of about 30 points to total willingness to pay. The result shows that the sanjiang plain wetland willingness to work is still a small part of total willingness to pay. The reason was partly due to the willingness to pay for the lower limit value of labor, is also likely reason respondents personal does not have enough time to go to work, or geographically respondents are not in the sanjiang protection zones, labor protection barriers and other factors.Research in sanjiang plain wetland protection value of the willingness to pay provides reference for lower limit value, for sanjiang plain wetland protection policy to provide a quantitative basis.
