Abstract: | 本文利用特徵價格法研究中國從2007年到2009年之間實行國三政策下消費者願付價格差異,討論汽車性能與油耗無顯著提升的情況裡,不同族群消費者為排放較優且加裝偵測系統之車輛願付價格改變。利用消費者實際購買價格、居住地及中國國家數據統計網的資料,通過五個不同變數設定的特徵價格模型研究不同社會經濟條件下強制性(中國減排法規)與非強制性(歐洲減排法規)法規環保特徵對願付價格的影響,並以估計之價格提升區間計算新法規之減排成本。研究發現,擁有新環保特徵的車款購買價格有所提升,消費者對中國和歐洲法規下減排特徵的願付價格提升區間分別為3770到5860元和3590到3880元,且願付價格可能隨著擁有更多的環保特徵而提高。地區虛擬變數估計結果顯示,居住在較發達地區的消費者對強制性法規下的環保特徵改變願付價格下降,但對非強制性法規的願付價格上升,這樣的異質性可能來源於消費者對車輛性能的覺察力差異導致;加入人均GDP和環境保護支出的估計結果發現,環保支出的上升可能會降低消費者對環保車款的願付價格,人均GDP的估計結果在經濟意義上則與地區差異一致。此外,雙重差分法對銷量的估計結果與願付價格在經濟意義上一致,購車預算較低的消費者相對於預算較高的消費者對環保車的偏好有更大幅度的上升。 This paper employs the Hedonic Price Model to study the differences in consumers' willingness to pay under the implementation of the China III emissions standards from 2007 to 2009. It discusses the changes in WTP for vehicles with superior emissions and equipped with detection systems among different consumer groups, under the scenario where there is no significant improvement in vehicle performance and fuel efficiency. By utilizing consumers' actual purchase prices, residence locations, and data from the National Bureau of Statistics of China, this study examines the impact of mandatory and non-mandatory regulation on vehicle WTP under various socioeconomic conditions through Hedonic Price Model with four different settings. The WTP increase for emission reduction features under Chinese and European regulations ranges from 3,770 to 5,860 RMB and 3,590 to 3,880 RMB, respectively. Consumers' WTP for environmental features may increase as the number of environmental features grows. The estimation results of regional dummy variables indicate that consumers living in more developed areas show a decreased WTP for environmental features under mandatory regulations but an increased WTP under non-mandatory regulations. The inclusion of per capita GDP and environmental protection expenditure in the estimation reveals that an increase in environmental protection expenditure might reduce consumers' WTP for environmentally friendly vehicles. Difference-in-Differences estimation results indicating that consumers with lower purchase budgets exhibit a larger increase in preference for environmentally friendly vehicles compared to those with higher budgets. |
