摘要
本文針對民眾透過問卷調查其對核能發電的風險態度,並應用預期效用理論之風險貼水與等值現金概念,分析民眾對於核能電廠發展所持的風險態度。研究發現不論贊成或是反對核電發展者,幾乎所有受訪者對核電發展之風險態度都是屬於風險趨避;在各種設想預期所得情境水準下,反對核電者都較贊成者更為風險趨避。在較低的預期所得水準的假設情況下,贊成者較不規避「廢止核電」的風險,而反對者卻較規避「發展核電」的風險;但在較高設想預期所得的假設情況下則相反。在願意支付金額以避免風險所帶來可能損失的痛苦方面,反核者的願付金額明顯高於贊成核電發展者之願付金額。因此,核電反對者相對於贊成者,更懼怕其所面對的風險。

This study applied the standard reference contract of expected utility theory to explore the public risk attitudes towards nuclear generation policy through a questionnaire survey. The results indicated that risk aversion is the prevalent risk attitudes no matter the pros or cons of nuclear generation. The cons are more risk averter than the pros. Judging from the parameters of risk coefficients it is evident that the degree of risk aversion is relatively lower among those pros but higher among those cons under the low income contingent scenario. Under the high income contingent scenario, on the contrary, the degree of risk aversion is relatively lower among those cons but higher among those pros. Judging from the certainty equivalent the cons are willing to pay more than those pros to avoid the nuclear risk. The results implied that the pleasure from gains is lower than the suffering from the losses of nuclear risk among the pros and cons. Therefore, the cons are relatively more afraid of nuclear risk.
