本研究的目的為研究國中九年級學生在學習機率單元前後，對於機率概念的了解與代表性偏誤、可利用性偏誤Kahneman＆Tversky(1974)）及結果取向判斷偏誤(Konold1989)的異同。主要採量的分析，以自訂的問卷評量工具對受試者進行筆試。研究之樣本為學過國小簡單機率的國中九年級學生，問卷實施的方式為筆試，研究過程設計了前測、後測兩份試卷，並在施測前進行預試來評估試題信度、效度。前測問卷施測目的在探討學生在教學前利用常識、直觀來解題所可能造成的機率偏誤。教學過後也進行後測問卷的施測，並利用前後兩次施測的結果，探討國中生在教學前後機率判斷偏誤上的差異性。本研究之對象為中學九年級學生，共148位學生來進行施測，研究者依學生數學分組教學之成績，分為高分群、中間群、低分群，依據性別和分群兩個變項來進行分析。分析結果發現： 1.性別變項無顯著差異，故教學過程中不用特別考慮性別差異。 2.分群分析結果如下： (1)結果取向 在一次投擲問題中，前、後測問卷分析結果發現，中、高分群前後測整體表現皆無偏誤的比例較低分群來的少。 (2)代表性偏誤 在代表性偏誤中的正時近效應與負時近效應的問題中，低分群在前、後測仍犯有偏誤比中、高分群前後測都犯有偏誤的比例來的高。而改變樣本空間問題中，中、高分群在前、後測皆沒有偏誤的比比例較低分群高。複合樣本問題中探討代表性偏誤，低分群在前、後測仍然有偏誤的比例較中、高分群前、後測犯有偏誤高。 (3)可利用性偏誤 三群在前、後測的綜合表現並無顯著差異。 / The study aims to explore the differences of judgmental heuristic and biases on representativeness, availability (Kahneman &Tversky, 1974) and outcome approach (Konold, 1989) in terms of comprehension of probability concepts by ninth graders before and after studying the subject. The results are based on a quantitative analysis of the data collected from two sets of paper-and-pencil self-designed questionnaires. Pre-test questionnaire is meant to explore students’ potential probability biases when they work out the problems based on their previous knowledge and intuition prior to any instruction, while post-test questionnaire is conducted after instruction. The subjects in our experiment are composed of one hundred and forty-eight ninth graders who have only learned some basic probability concepts in primary school, and are classified into high-, mid- and low-scorer groups based on their previous academic performance. The findings suggest that: 1. Gender effect is not significantly different, so there is no need to pay attention to the gender difference in teaching process. 2. The results of analyses for different groups are listed in what follows. (1) Outcome approach: In the problem of tossing a coin, the results of pre-test and post-test indicate that the proportion of subjects who are without biases is higher in mid- and high-scorers than that of low-scorers. (2) Representativeness bias: In the problem of positive recency effect and negative recency effect, the proportion of committing biases is higher in low-scorers than that of mid- and high-scorers in both pre- and post-tests. In the problem of changes in sample spaces, the proportion of lack of biases is higher in mid- and high-scorers than that of low-scorers. In the composite-event problem that deals with representative biases, the proportion of committing biases among low-scorers is higher than that of mid- and high-scorers in both pre- and post-tests. (3) Availability bias: There is no significant difference in the overall performance of pre- and post-tests among the three groups.

本研究主要的研究目的有二：其一，探討高社會焦慮者對不同情緒臉孔的注意力時間歷程；其二，探討自動化階段與控制式階段所進行的注意力訓練，對於降低注意力偏誤以及改善社會焦慮的效果。基於上述兩項研究目的，分為研究一與研究二進行。研究一中，共有60名參與者完成眼動作業，其中高、低社會焦慮組 (HSA組/ LSA組) 各30名。在眼動作業中，生氣、難過、快樂與中性四類情緒臉孔同時呈現於螢幕上，參與者被指示自由觀賞螢幕上的圖片，直到圖片消失。研究一的結果發現，HSA組對生氣臉的初始注視時間 (initial gaze duration; IGD) 明顯高於LSA組，且高於其它三類情緒臉孔，LSA組對四類情緒臉孔的IGD則沒有差異；其次，LSA組對快樂臉的整體凝視時間比例 (proportion of total viewing time; PTVT) 明顯高於HSA組。時間歷程分析的結果發現，HSA組在751-1000 ms 對生氣臉的凝視可能性高於LSA組，以及在7-8 s對難過臉的凝視可能性高於LSA組；LSA組在9-10 s對快樂臉的凝視可能性高於HSA組。研究一結果指向，高社會焦慮者對威脅刺激可能有注意力脫離困難，同時可能缺少對正向刺激的注意。研究二共有72名高社會焦慮者參與，本研究將注意力訓練的刺激呈現時間操弄為100 ms或500 ms兩種，每一種刺激呈現時間的注意力訓練可分為注意力改變組 (AMP組) 與注意力控制組 (ACC組) 兩種情境，因此共有AMP-100、ACC-100、AMP-500與ACC-500四種訓練情境。所有參與者被隨機分派至四種訓練情境中，並完成八次 (每週兩次，為期四週) 的注意力訓練作業。參與者在注意力訓練的前、後分別完成量表填寫、修改版Posner作業與眼動作業的評估，並且在注意力訓練結束至少一個月後，接受追蹤階段的評估。研究二的結果發現，100 ms的注意力訓練可以增進AMP-100組在修改版Posner作業上對所有無效嘗試次的反應時間；降低其在眼動作業上對生氣臉的IGD；同時改善AMP-100組參與者的負向評價恐懼、互動焦慮以及演講前的預期焦慮。500 ms的注意力訓練可以降低AMP-500組的參與者在修改版Posner作業上對社會威脅詞無效嘗試次的反應時間；減少其在眼動作業上對負向情緒臉孔的注意力維持時間，並增加對正向情緒臉孔的注意力維持時間；同時降低AMP-500組的負向評價恐懼與社會互動焦慮。研究二結果顯示，自動化階段與控制式階段所進行的注意力訓練，均可促進高社會焦慮者對威脅刺激的注意力脫離速度，並且改善社會焦慮。本研究於討論中，針對本研究結果在理論與臨床應用上的意涵進行探討，並提出本研究的限制與對未來研究的建議。 / The purpose of the present study was twofold. First, it aimed to investigate the attentional processing of emotional faces in social anxiety using the eye-tracking technique. Second, it tried to examine the effects of attentional training in reducing attentional bias and in decreasing social anxiety symptoms in high socially anxious individuals. In study 1, a total of 30 high socially anxious (HSA) and 30 low socially anxious (LSA) participants completed the eye-movement task. In the eye-movement task, participants were instructed to view the slides on the monitor naturally. Each slide contained 4 emotional faces (one angry, one sad, one happy and one neutral face). The results showed that the HSA participants had longer initial gaze duration (IGD) on angry faces than the LSA participants did. Further, the LSA participants had higher proportion of total viewing time (PTVT) on happy faces than the HSA participants did. Time-course of attention to emotional faces was also examined. The results showed that the HSA group had higher fixation probabilities to angry faces than the LSA group did in the 751-1000 ms time window. The HSA group exhibited higher fixation probability to sad faces than the LSA group did in the 7-8 s time window. Further, compared with the HSA group, the LSA group had higher fixation probability on happy faces in the 9-10 s time window. The results of study 1 indicate that individuals with high socially anxiety may have difficulty in disengagement form social threatening information and may demonstrate decreased attention to positive information. In study 2, seventy-two high socially anxious participants completed the experiments. In the attention training task, stimuli were presented at two durations: 100 ms and 500 ms. Participants were randomly assigned to four different attentional training conditions, including the AMP-100 (attention modification program; presentation duration = 100 ms), the ACC-100 (attention control condition; presentation duration = 100 ms), the AMP-500 and the ACC-500 group. All participants completed eight attentional training sessions delivered over four weeks (i.e., twice weekly sessions). Participants were also required to complete preassessments, postassessments and follow-up assessments. The results demonstrated that the 100 ms attention modification program facilitated attention disengagement in the Modified Version of Posner task and decreased attentional maintenance to angry faces in the eye-movement task for participants in the AMP-100 group. Furthermore, it reduced the fear of negative evaluation, interaction anxiety and anticipated anxiety for public-speaking situation in the AMP-100 group. The 500 ms attention modification program facilitated the disengagement from social threat words in the Modified Version of Posner task in participants of the AMP-500 group. It also decreased the attentional maintenance to negative faces and increased the attentional maintenance to happy faces in participants of the AMP-500 group. Further, it reduced the fear of negative evaluation and social interaction anxiety in the AMP-500 group. The results of study 2 suggest that attention modofication programs may decrease difficulty in disengagement from threat and reduce some aspects of social anxiety symptoms in individuals with high socially anxiety. Theoretical and clinical implications of these results were discussed.

由於以往在願付價格的研究中，並未考慮到價格再高都願意支付的受訪者，以及價格再低都不願意支付的受訪者，因此可能會造成估計結果的偏差。本文除了沿用Tsai(2005)所建議採用的三要素混合模型，將受訪者區成價格再高都會願意付的人、願意付合理價格的人以及價格再低都不願意付的人等三類受訪者，且將願意付合理價格者的願付價格透過加速失敗模型(accelerated failure time model，簡稱AFT model)來作評估外，進一步就願意付合理價格的人可能會受到起價點的影響或是有「定錨效果」(anchoring effect)產生的問題來作探討，並就CVDFACTS的高血壓之願付價格資料來作實證分析。結果發現教育程度越高、收入越高以及男性對於能降低罹患心臟血管相關疾病新藥的願付價格也越高。此外我們也發現此筆資料確實有起價點偏誤(starting point bias)的情形。 / In the past, studies on willing-to-pay (WTP) usually assume that all the respondents are willing to pay a reasonable price for a non-market good. In reality, some of the respondents might be willing to pay a very high price, while some others unwilling to pay anything. Following Tsai(2005), we adopt a three-component mixture model to take into account these there three types of respondents and modeling those who are willing to pay a reasonable price with an accelerated failure time (AFT) model. In addition, with a slight modification, we also incorporate issues regarding “starting point bias” and “anchoring effect” into the model. An empirical study based on the data collected from “CVDFACTS” shows that males, respondents with higher educational level, and those with higher family income are willing to pay higher prices for a new hypertension treatment. In addition, it is quite likely that “starting point bias” exists in the dataset.

本文利用國內投資人參與民國八十五年一月至八十九年四月間77家IPO競價拍賣的投標資料為樣本，來探討投資人過度自信以及自我歸因偏誤的情形。實證結果發現:過度自信假說於對個人投資人在初級市場的投資行為仍有適用，並且男女皆有過度自信的現象，但沒有足夠證據顯示男性較女性過度自信。最後當投資者上次報酬為正時，投資者會更積極的投標。而上次報酬為負時，對其下次投標標價的影響並不顯著。此點符合自我歸因假說的推論。

本研究的主要目的在於探討美沙冬的使用者是否具有抑制控制能力缺損、對海洛因相關刺激是否具有注意力偏誤，以及是否有彈性認知轉換能力上的問題。 研究使用的是Noel等人（2005,2007）發展出來的Go/No-Go作業，並使用海洛因圖片與中性圖片為作業刺激，分別測量受試者在作業中的反應正確率、反應遺漏數、反應犯錯數、平均反應時間、決定偏誤與區辨度，並且使用依賴嚴重度量表，以了解受試者對海洛因的依賴嚴重度與Go/No-Go作業各指標之間的相關。 　　美沙冬組樣本選取自八里療養院土城門診部之接受美沙冬治療者，共17人，經由網路招募之健康控制組十九人，受試者一共三十六人。共變數分析之結果顯示在Go/No-Go作業的正確率、遺漏數、區辨度和決定偏誤等指標上，發現組別與情境轉換之交互作用，顯示使用美沙冬之受試者具有彈性認知能力上的缺損，因此在有轉換的區段之中，無法快速地適應新的作答規則。此外，Go/No-Go作業結果未發現美沙冬使用者之抑制缺損與對海洛因相關圖片之注意力偏誤之現象。 　　依賴嚴重度與Go/No-Go作業的指標相關研究則發現，其依賴嚴重度越高，其在非轉換情境中對海洛圖片的犯錯數越低、決定偏誤越高，顯示美沙冬使用者似乎在沒有情境轉換的區段中，會將其注意力資源分配在海洛因圖片上，忽略非海洛因圖片，顯示其注意力較具選擇性。 / The goal of this study is to explore the inhibitory deficits、attentional bias towards heroin-related cues and cognition flexibility of current methadone users. The Go/No-go task used here was previously developed by Noel et al. (2005, 2007). Heroin-related pictures and neural pictures were presented as targets or non-targets. Accuracy rate、omission、commission、average reaction time、decision bias(C) and discrimination (d’) were being measured individually. The relation between the severity of heroin dependence and task performance was also investigated. The 17 subjects in methadone group were currently methadone maintenance treatment patients from Bali psychiatric center, and the 19 control group subjects without a drug using history were recruited by internet advertisement. The covariance analysis revealed interactions of group and shift/non-shift condition on accuracy rate、omission、decision bias(C) and discrimination (d’), indicating a cognitive flexibility deficits in methadone users. They had difficulty adapting to new rules in shifting conditions. No inhibitory deficits or attentional bias were found so far in this study. The relation between heroin dependence and Go/No-go task performance revealed that the more dependent the methadone subjects were, the less commission errors they made, the higher decision bias score they got towards heroin pictures in non-shifting conditions. It seemed that the methadone users were prone to allocate more attention resource to heroin-related pictures in non-shifting conditions, suggesting a more selective attention process.

本篇論文應用Rubin (1973)、Rosenbaum and Rubin (1983、1985a,b)所發展的配對方法(Matching Method)探討兩個議題，其一是評估企業從事社會責任行為是否可以改善績效，另一則是探討銀行加入金控後對其績效的影響。 / 針對第一個議題，我們將FTSE All-share 指數中被收錄於英國FTSE 社會責任指數的成份股定義為社會責任企業，未被收錄者定義為非社會責任企業，應用配對方法，根據特性變數是否相近為依據進行樣本配對。實證結果發現，不論使用配對前或是配對後的樣本進行分析，皆找不到社會責任企業的平均績效優於非社會責任企業的證據；相反地，部分的證據顯示社會責任企業的財務績效相對較低，因此我們的分析結果傾向支持焦點移轉假說，社會責任行為對財務績效的影響效果為負。 / 另外，我們以遠見雜誌於2006 年公佈的企業社會責任調查為基礎，將衡量企業社會責任績效的三個層面－社區參與、環境保護與財務透明，透過投資組合分析與迴歸分析來評估公司承擔社會責任與財務績效之間的關聯性。實證結果發現，第一，平均來說，公司的社會責任評分愈高，在評比結果公佈後的股票報酬愈低，兩者之間呈現負向關係；第二，公司在不同層面的社會責任行為對於股價報酬的影響具有差異性；第三、透過公司的長期財務資料發現，社會責任評分高的公司其長期平均會計績效相對較佳，但長期平均的股票報酬相對較低，表示社會責任型公司不一定是一個好的投資標的；最後，我們找不到支持社會責任行為可以做為公司績效保險的證據。本文使用各別層面的評比指標，更廣泛地評估社會責任行為對財務績效的影響，改進既有文獻中僅使用單一指標的不足之處。 / 就第二個議題而言，同樣地應用配對方法，根據銀行的特性變數是否相近為依據進行樣本篩選，利用台灣上市上櫃的銀行在2002 年第1 季至2006 年第2季的資料，我們發現在樣本配對前，平均來說，金控銀行在15 個CAMEL 績效指標的表現上皆相對較佳；樣本配對後，金控銀行除了在費用比率之外，其他的評比指標仍相對優於獨立銀行；不論使用配對前或配對後的樣本做分析，皆未出現金控銀行績效顯著較差的證據，因此，我們的實證結果偏向支持綜效假設，銀行加入金控對績效的影響效果為正向。 / 我們的研究架構與方案評估與政策衝擊分析文獻中的方法相一致，而貢獻則在於我們考慮樣本之間特性變數的差異性，進而以樣本配對的方式修正這個差異性，將有效降低既有文獻中在檢驗上述兩個議題上的選擇偏誤問題。 / In this thesis, we apply several matching methods, develop by Rubin (1973)、Rosenbaum and Rubin (1983, 1985a,b), on examing the effects of Corporate Social Responsibility (CSR) on firm financial performance (CSR-effect) and on evaluating the effects of banks being subordinated to FHC on CAMEL indicators (join-FHC effect). / For the former application, two competing hypotheses, social impact hypothesis and shift of focus hypothesis, are proposed, where the former suggests that CSR has a positive relation with performance and the latter are opposite. To ensure the CSR-effect is not contaminated by other factors or the sample is randomly drawn, we employ four matching methods, Nearest, Caliper, Mahala and Mahala Caliper to match the characteristics of the firms with CSR (CSR-firms) and without CSR (NonCSR-firms) to get rid of sample selection bias. Although the four methods yield slightly different results, to our surprised, firms engaging in CSR activities obtain lower values on the return on assets, return on equity, return on sales and earnings per share. Therefore, CSR at the very least does not improve the firm performance, supporting the shift of focus hypothesis. Engaging in CSR activities lead to more pain than gain, at least in the short run. / On the CSR topic, using a set of disaggregated social performance indicators for community participation, environmental protection and fiancail transparency from the Global Views Monthly, we examine the relationship between CSR and financial performance of TSE listing companies. Our main results show that first, scores on composite social performance indicators are negatively related to stock returns and this relationship cannot be rationalized by multi-factor models for explaining the cross-sectional variation in stock returns. Second, the effects of three disaggregated social performance indicators on stock returns are differenct among industries. Third, aggregated social performance indicator is positively related to long-term accounting performance but negatively related to long-term market performance, and thus implies that good companies are good in books, but not good investments. Finally, firms with high CSR ratings do no exhibit smaller decline of their financial performance during stagnations and thus not support the view that CSR is insurance of financial performance. / The second application, two hypotheses, synergy hypothesis and specialization advantage hypothesis, are raised too, where the former suggests that FHC-banks performer better and the latter are contrary. Above four matching methods are still used to fix the characteristics of two groups of banks in order to correct for sample selection bias. Based on after-matching samples, most of our empirical results suggest that FHC-banks, on average, outperform independent banks on most of indicators on capital adequacy, asset quality, earning ability and liquidity but not on management ability and being FHC-banks at the very least does not deteriorate the performance of banks, making our conclusion favors the synergy hypothesis and against specialization advantage hypothesis in Taiwan. / Our framework is identical to many applications of matching method such as Persson (2001), Hutchison (2004), Glick, Guo and Hutchison (2006), and are also parallel to standard medical and biological research.

本研究主要目的為，運用點偵測作業探討高社交焦慮者面對環境中的社會威脅訊息的注意力處理歷程，並釐清在實驗中加入誘發社交焦慮情緒程序對高社交焦慮者的注意力處理是否造成影響。由於過往研究對高社交焦慮者對社會威脅訊息的注意力處理意見分歧，學者們分別提出過度警覺－逃避假設與過度警覺－難以轉移假設，兩假設皆有相關理論與研究支持，本研究企圖檢驗這兩個假設的合理性。 　　本研究篩選出高社交焦慮組30人與低社交焦慮組30人參與實驗，受試者在接受所分派的情緒誘發程序後，進行以生氣臉與嫌惡臉所組成的威脅臉為實驗刺激的點偵測作業，以評估個體對威脅的注意力。 　　研究結果發現，接受社交威脅誘發程序的高社交焦慮者對社會威脅訊息的注意力處理，傾向為過度警覺－逃避假設的歷程，對威脅產生警覺後，便逃避對威脅的處理；而接受中性情緒誘發程序的高社交焦慮者對社會威脅訊息的注意力處理，傾向為過度警覺－難以轉移假設的歷程，對威脅產生警覺後，便無法將注意力自威脅轉移。 　　高社交焦慮者對社會威脅訊息，有明顯的注意力偏誤，且此偏誤會隨個體所處的情境與接觸威脅的時間而有所變化。由於這些偏誤扮演著維持個體的社交焦慮的重要角色，故在釐清高社交焦慮者在不同情境下對威脅的注意力處理後，有助於選擇適當的治療策略，協助高社交焦慮者因應環境中的威脅。 / The purpose of the present study was to utilize the dot-probe task to investigate the attention processing for social threat in high social anxiety, and to know what under conditions of social threat influence. Owing to the conflicts of the past studies, there are hypervigilance-avoidance hypothesis and hypervigilance-difficult to disengagement hypothesis for the attention processing. This study attempt tests the rationality of the two hypotheses. Performance on a face-probe task was assessed in high (n=30) and low (n=30) social anxiety. After participants were assigned the mood induction procedure randomly, they were presented the task. The results revealed that under conditions of social threat high social anxiety are at first vigilant of threat faces, and avoid them. And under conditions of neutral high social anxiety are at first vigilant of threat faces, and difficult to disengage them. These results suggest that the attention bias for social threat in high social anxiety would be changed by the context and how long the individual face the threat. Know that the attention processing for social threat in the different context in high social anxiety would help the psychologists to choice the applicable therapy for high social anxiety.

本研究旨在檢證雙元自主性模型中自主能力與情境操弄對訊息區辨表現的範疇優勢性運作機制；並為了排除過去系列相關研究結果可能受到共同方法變異偏誤所造成的效度威脅，本研究採取訊息區辨表現作為非自陳式效標變項，重新檢證雙元自主性模型的各項主張觀點。 本文共包含兩個研究，研究一經由811位台灣北部與南部的高中職三年級學生，以班級作為單位進行團體施測，測量其個體化與關係雙元自主能力，並透過情境中強調不同適應訴求的操弄，探討雙元自主能力與情境操弄對訊息區辨表現的共同作用效果，以重複檢證雙元自主性模型中對（1）雙元自主能力可以共存，以及（2）不同自主能力各具有範疇優勢性的兩項主張觀點。研究一結果發現：個體化自主與關係自主兩種能力之間具有中度的正相關，再次支持雙元自主取向能力可以相互共存的主張觀點；但兩種自主能力彼此間仍具有可區辨的關聯效度，其中個體化自主能力主要作用於個人範疇的訊息區辨表現上，而關係自主能力主要作用於人際範疇訊息區辨表現上。另外也發現與區辨訊息範疇一致的情境操弄，相較於不一致的情境操弄或是不給予情境操弄，能強化範疇優勢性的作用效果。 為強化研究一的結果，研究二針對研究一的研究限制改善情境操弄的工具與訊息區辨作業，並以台灣北部大學生作為研究對象，其中61位雙元自主能力皆高的雙高組受試者，以及63位雙元自主能力皆低的雙低組受試者。分別邀請至實驗室進行個別的電腦施測，並透過情境脈絡中強調不同適應需求的操弄，再次探討雙元自主能力對訊息區辨表現的範疇優勢性運作機制，結果發現：首先，相對於雙低組，雙高組受試者在個人範疇與人際範疇的訊息區辨表現都比較好，重複檢證雙元自主能力對於訊息區辨的作用效果；其次，相較於不一致的情境操弄或是不給予情境操弄，與區辨訊息範疇一致的情境促發能提升個人範疇與人際範疇的訊息區辨表現。並且發現情境操弄的效果主要作用於發展出高度雙元自主能力的雙高組受試者，在雙低組受試者身上不同的情境操弄則沒有差異，不僅反映出雙元自主能力與情境操弄對訊息區辨表現的共同作用效果，並且重複地驗證雙元自主性模型中共存的理論觀點以及本研究對雙元自主性範疇優勢的運作機制推論。 本文並依據研究發現提出各項討論，論述雙元自主性模型與過去相關文獻與實徵發現的異同。像是（1）該模型採取適應能力的觀點重新詮釋自主性的多元發展取向，進行一系列的實徵研究並且獲得支持的研究結果；（2）採取情境與性格交互運作的系統觀點，說明雙元自主能力的共存與範疇優勢性動態機制；（3）透過非自陳式的訊息區辨表現杜絕共同方法變異的可能威脅，重複檢證該模型的各項理論觀點以及本研究的推論假設；（4）最後針對研究中各項不符合預期的結果提出合理解釋，並且說明未來值得繼續深入探討的相關議題。 / This article has two main goals about verifying the ideas of the Dual Autonomy Model (Yeh & Yang, 2006; Yeh, Bedford, & Yang, 2007; Yeh, Liu, Huang, & Yang, 2007). The first is testing the collective effect of dual autonomy and situational operation on message discernment to support the processing mechanism of the domain superiority hypothesis. The second is using the message discernments as performance criteria variable to prevent the common method variance bias and replicate the each hypotheses of dual autonomy. In study 1, 811 senior high school students from north and south of Taiwan as participants were asked to complete a group-survey in their classrooms. A medium correlation between individuating autonomy (IA) and relating autonomy (RA) replicates the coexistence hypothesis. It was also found a distinguishable criterion-validity confirms the domain superiority hypothesis that IA was greater associated with personal domain message discernment but RA was greater associated with interpersonal domain message discernment. This effect of domain superiority was enhanced only under the congruous situational operation condition, shows the collective effect of situation and autonomy capacity that verifies the processing mechanism of domain superiority. For strengthening the result of study 1, study 2 improves the situational operation materials and the message discernment tasks. 61 college students whose dual autonomy both are higher and 63 college students whose dual autonomy both are lower were recruited as participants for study 2 from school in north of Taiwan. They were invited to a small room separately and asked to complete all of the materials and tasks that were presented on computer. The participants with higher dual autonomy have better message discernments of both domains than the participants with lower dual autonomy, replicates the effect of dual autonomy on message discernments. The congruous situational operation produced greater message discriminations than incongruous or none situational operation. This situational effect was only significant on the participants with higher dual autonomy, shows the collective effect of situation and autonomy capacity, confirms the coexist of dual autonomy, and also verifies the processing mechanism of domain superiority. These results and limitations of these two studies, comparison with the past findings, and considerations for future research are discussed.

過去有關土地使用分區管制與地價兩者間關係之研究，往往假設地價在實施規劃管制過程中呈中立性，且過去在探討土地使用分區管制與地價二者間關係之研究時，多著重在探討土地使用分區管制施行後對地價之影響上，對於土地使用分區管制決策是否受到土地市場中地價之影響，則僅在少數的研究中被探討。故本研究首先透過國內外相關文獻之回顧與分析，得知規劃管制決策者有時為求得最大之政治支持，有可能會以規劃管制為其尋求最大政治利益之工具，而扭曲規劃管制之原意，使得土地使用分區管制決策可能受到土地市場中地價之影響，然而地價於實際經濟社會中是否會影響土地使用分區管制決策，則有待進一步的探討與驗證。 是以本研究以公共選擇理論與消費者效用理論為基礎，透過台北縣市土地使用分區管制決策過程與內涵之探討，利用羅吉特(logit)迴歸分析模型，以台北市為實證範圍，並以其72至81年度之房地移轉買賣實際調查資料，進行分年橫斷面分析方式，求取選擇性偏誤訂正項後，再納入地價方程式中估計，以求地價函數一致性估計，據以逐年檢驗地價對土地使用分區管制決策之影響情形。再以台北市信義計畫區為個案分析之對象，檢視於現實社會中地價對土地使用分區管制決策之影響情形。 經由上述之實證與個案分析，得到以下之結論： 一、土地使用分區管制決策在執政者追求最大政治利益之假設下，將可能受到利益團體等相關者之壓力，而做出只利於少數人之土地使用分區管制決策。 二、土地使用分區管制決策可能會受土地市場中地價之影響。 三、地價對土地使用分區管制決策之影響不穩定。 四、對土地使用分區管制決策時應有制度性之建立以審慎考量規劃管制之旨意。 / In the literatures, the study on. the relationship between land price and zoning control was assumed that land price is neutral. Moreover, the studies of land price and zoning control are more on the impact of land use control upon land price. The issue that impact of land prices upon the decision making of zoning control is rarely investigated. Based upon the theories of public choice and consumer's utility, this study discusses the process and content of zoning control decision-making. Then, by Logit model, the transaction data of property in Taipei City from 1983 to 1992 are employed to test the impact of land price upon the decision making of zoning control. Furthermore, a case study of Shin-I Planning District in Taipei City is analyzed so as to examine the impact of land price upon zoning control decision-making in the real operation. The major findings of this study are that, land price may affect the decision making of zoning control in the long term. However, the impact of land price upon the zoning control decision-making is unstable. Finally, based upon the public choice theory, the empirical results are discussed so as to apply the findings to the land policy.

有鑑於全球愈來愈重視企業營運對社區造成的社會、環境和經濟影響，企業的利害關係人除了重視企業的財務績效之外，也愈來愈關心企業是否有善盡其「社會公民」的責任與角色。企業責任報告之目的就是在傳統的財務報表之外，進一步揭露企業的營業活動對於社會及環境所造成的影響。為了使資本市場能更有效地運作，公司管理當局應該要揭露範圍更廣、透明度更高、並有助於投資決策的攸關性資訊，因此，發布社會責任報告的企業有日益增多的趨勢。本研究之目的即在探討三個與企業責任報告有關的議題：(1) 企業的公司治理結構之良窳與管理當局企業責任報告揭露決策的關係；(2) 企業揭露社會責任報告之決策是否會產生股價溢酬；(3)企業社會責任報告揭露決策對企業的事前權益資金成本的影響。在控制樣本的自我選擇偏誤之後，本研究的主要發現有二：第一、公司治理結構愈好的企業愈傾向於揭露企業責任報告，而且也愈可能以專節的形式在該報告中揭露公司治理資訊；第二、從有無揭露企業責任報告的角度來看，本研究發現有揭露的公司均有較高 (低) 的股價 (資金成本)。其次，從揭露的內容做進一步分析之後，本研究發現「環境績效」、「社會績效」與「公司治理」三大類內容的揭露決策均具有價格溢酬。至於「企業承諾」則對公司股價並無顯著影響。最後，企業責任報告揭露程度較高之企業會有較顯著的價格溢酬以及較低的資金成本。 / In light of the increasing emphasis on companies’ social, environmental and economic impacts on the communities, stakeholders are more concerned about whether firms appropriately assume their responsibility as a social citizen. To fulfill stakeholders’ demand of such non-financial information, many companies have recently begun to voluntarily issue the corporate responsibility reports (CRR) as a means to disclose their social, environmental and economic performance and their commitment to do business responsibly. This study intends to answer the following three key questions related to the CRR disclosure: (a) Will companies with stronger corporate governance be more willing to issue CRR? (b) Will the voluntary disclosure of CRR leads to stock price premium? (c) Will companies making voluntary disclosure of CRR have lower ex ante cost of capital? After controlling for the self-selection bias, the empirical results reveal several important findings. First, the stronger the companies’ coporate governance, the more likely the management will issue CRR. Particularly, these companies tend to disclose their comporate governance policy and procedures in a separate section in the CRR. Second, companies disclosing CRR experience significantly higher (lower) stock prices (cost of capital). A further examination shows that three out of four major components reported in the CRR (i.e., environmental performance, social performance, and corporate governance) give rise to significant price premium. The disclosure of business commitment, however, seems to bear little or no information content embedded in the stock price. Finally, companies disclosing more information in their CRR have higher price premium and lower cost of capital than those disclosing less information. The implications of these findings are discussed.
