基于CVM的建筑废弃物回收利用非市场价值评估

Evaluation of the non-market value of construction waste recycling based on contingent value method

本研究以建筑废弃物为研究对象,通过问卷形式调查绵阳市居民对建筑废弃物回收利用非市场价值的认知以及支付意愿,在此基础上采用条件价值法（contingent value method,CVM）对建筑废弃物回收利用的非市场价值进行核算和评估,并分析影响居民支付意愿的因素.结果显示：2015年绵阳建筑废弃物回收利用非市场价值为8.29亿元,占2015年绵阳市建筑业总产值的2.19%;城市,农村居民的平均支付意愿分别为584.88元/（户每年）和208.08元/（户每年）,分别占家庭年平均收入的0.91%和0.55%.由此可知,建筑废弃物回收利用非市场价值巨大,但平均支付意愿在家庭年平均收入中所占比例较低,说明居民对建筑废弃物回收利用非市场价值支付意愿还很低.研究发现,居民对建筑废弃物价值的认知程度和政府对建筑废弃物回收利用经费的透明化管理是影响城乡居民支付意愿的主要因素.因此,加强建筑废弃物回收利用宣传教育和经费透明化管理,是提高居民支付意愿,改善建筑废弃物回收利用现状的有效手段.

This paper evaluates the non-market value of construction waste recycling based on contingent value method, through investigating Mianyang residents＇ cognition and willingness to pay for the construction waste. The result shows that the non-market value of the construction waste recycling in Mianyang is 829 million yuan, and accounts for 2.19% of total output value of construction industry of Mianyang in2015. The annual willingness to pay of urban and rural residents in 2015 is 584.88 yuan per household and 208.08 yuan per household, and accounts for 0.91% and 0.55% of annual household income respectively.This indicates that the non-market value of construction waste recycling has high non-market value, but the amount of residents＇ average willingness to pay accounts for a lower-proportion in their annual household income, which means that the residents＇ willingness to pay is still low. The key factors affecting the willingness to pay for urban and rural residents are cognitive level of construction waste and transparent management of construction waste recycling funds. Therefore, strengthening publicity and education on the construction waste recycling and transparent management of the funds for construction waste recycling are effective means to improve the residents＇ willingness to pay for the construction waste.
