我國監理機關為強化保險公司之財務能力，有效監管保險公司之風險狀況，特於2003年7月9日，正式引進美國風險基礎資本額制度(Risk-Based Capital, RBC)，作為監理保險公司清償能力之工具。RBC制度除了改善單一資本額規定的缺失外，亦反映了保險公司之經營風險，對於保險公司面臨風險所需資本有較妥適的規範。讓監理機關得以藉此工具發現體質較弱之保險公司，進而採取適當之行動。 本文檢視我國壽險公司在RBC制度前後，資本與風險間之關係。探討RBC制度實施後，對於我國壽險公司之資本比例、資產風險以及產品風險是否確實造成改變，能使壽險公司之資本提列與公司風險大小有一正向搭配，在保險公司面臨越高的風險狀態時，願意提列更多資本做為緩衝，以保障公司安全。藉此分析觀察RBC是否達到預期之功能，以作為我國監理機關實行RBC制度之參考。 本文使用聯立方程式部分調整模型，以二階段最小平方法進行檢測。實證結果發現，在RBC制度實施後，壽險公司之資本比例對資產風險以及產品風險具有顯著負向關係，顯示資本比例低者所承擔之風險較高，而資本比例高者風險較低。此外，公司規模以及公司型態對於壽險公司之資本與風險具有顯著影響力，外商壽險公司之資產風險較本土壽險公司為低。 / Risk-based capital (RBC) has been implemented as an important regulatory tool for the insurance industry in Taiwan since year 2003, which is used to strengthen the financial capability and to predict the probability of insolvency. It not only improves the shortcomings of single capitalization index but also reflects the business risks. Moreover, it lets the regulator be able to apply this tool to discover the insurance companies with weak financial management and take the suitable actions. This paper explores the changes on the capital ratio, asset risk and product risk in life insurance industry in Taiwan before and after the RBC regulation and verifies if the implementation of RBC had a positive effect on the relationship between capital and risks. To examine this issue, this study uses a simultaneous-equation partial-adjustment model with two-stage least squares method. The results suggest that the life insurers with lower capital ratio take higher asset risk and product risk, while life insurers with higher capital ratio take lower asset risk and product risk. For life insurers, company size and type also have an important impact on their capital and risks. The empirical finding shows that there is lower asset risk in the international insurers than domestic insurers.

我國保險業監管制度之實施，以2003年7月之RBC制度影響最為重大，因此本研究希望檢驗RBC制度對於壽險公司之經營策略，是否有顯著之改變，而保險公司之經營策略中，又以資產配置與產品組成為最重要的議題，兩者將影響資產風險與產品風險。因此本研究將重點聚焦於壽險公司之資產風險與產品風險於RBC制度實施前後之變化，藉以探討是否RBC制度實施後，保險公司對於經營中涉入風險之行為，保有更穩健之思維，而不違反RBC制度實施立意之良好。 本研究整理我國25間壽險公司之財、業務之資料為分析基礎，並以簡單複迴歸之研究方法為實證分析。實證結果中，壽險公司於RBC制度實施後有風險抵換之情形，但無論資產風險及產品風險都與前期資本比例為負向關係。另外，小型公司中資本比例越低者，有增加投資於高風險資產的比例；並且小型公司中，前一期經營結果越差，銷售越高風險產品的比例將會上升。 / One of the most important supervision system in insurance industry is the implementation of Risk-Based Capital system in 2003 in Taiwan. In this study, we examine whether the business strategy of life insurance companies changes significantly because of the implementation of RBC system. In insurance’s business strategy, asset allocation and product composition are the main issues and both will influence asset risk and product risk. Hence, we focus on the changes in asset risk and product risk to find that whether life insurance companies have more stable operating concepts after the implementation of RBC system. We use multiple regression model to analyze the relationship between asset risk, product risk and capital ratio of the life insurance companies. The results suggest that there are a negative relationship between asset risk, product risk and capital ratio after the implementation of RBC. Besides, the small size companies which have low capital ratio will tend to increase the proportion of risky assets in their investment. And small size companies which have worse operating outcomes in the previous year will increase the proportion of high-risk products they sell in current year.

房屋預售制度是國內不動產業的一大特色，而長期以來國內對房價的研究皆著重於成屋價格，且大都以特徵價格法分析成屋價格屬性，對預售屋價格的形成及成屋與預售屋彼此價格相互影響一直缺乏深入的研究。造成政府管理及業者經營上的困擾，也直接威脅到購屋的權益，因此透過預售屋價格理論層次的探討，將有助於學術界對房屋預售制度的暸解。 由於房屋預售的交易標的為土地及房屋預售契約，而此約定於未來特定時間交貨之契約買賣形式，基本上即具有遠期交易與期貨的性質。因此本文利用儲存理論於無套利均衡的情形下，依序考慮有無不動產市場景氣變動與預售屋產品風險，來加以推演預售屋價格，最後導出預售屋訂價模式為成屋價格加成屋的持有成本，減預售屋的履約保證費用，加上預期景氣變動價差。模式中預售屋產品風險及市場景氣變動因素的考慮，為本研究學術上的主要貢獻。 進一步利用特徵價格方程式來固定品質，使成屋與預售屋在相同的基礎上比較，並藉由太平洋房屋所提供之民國77年∼82年大台北都會區實際成交案例8885筆來試驗。發現期間預售屋每戶價格平均比成屋高出33．08萬，即就大台北都會區的房屋市場而言，購屋者於此期間選購成屋較有利、比較各年之預售屋與成屋價格，除77年之基差為負以外， 78年∼82年的基差都大於零，其中基差變動的原因，可由本研究所建立之理論模式來加以詮釋。最後應用理論模式來分析房屋市場的基差，說明國內預售屋價格大多高於成屋價格的原因，並詮釋理論模式的政策意涵，與對購屋決策及建商經營的應用。 / The pre-sales housing system in Taiwan is a quite unique method allowing home buyers to speculate on or purchase their houses. The prices of pre-sales houses have become a leading indicator of the housing cycle in the market. However, limited knowledge is availab1e regarding how and why pre-sales house prices are determined, or what is the relationshiP between the pre-sales and existing house prices. 　 Determining Whether the theories of forward or futures transactions can account for the pre-sales house pricing behavior is highly desired since one characteristic feature of the pre-sales syStem is its similarity to forwqrd of futures transactions. In this study, an arbitrage perspective is used to discuss the difference (basis ) between pre-sales and existing house prices. Based on the storage theory, a pricing model suitable for pre-sales houses in Taiwan was established steP by step under the considerations of the presence of expected market changes, and the risk of product uncertainty in pre-sales houses.The price of pre-sales houses is equal to the price of existing houses on the transaction date plus the carry cost, and the price difference resulted from expected market changes minus the contract guarantee cost. The established model was then used to analyze the 8885 actual transaction cases provided by the Pacific Rehouse during l988 and l993. We used hedonic price. theory to analyze the differences between pre-sales and existing house price. As far as the overall market is concerned, the analysis found that the difference between the pre-sales house price on the transaction date and the price of the existing house was NT$330,800/unit. The basis was positive in l988 and negative during l989 and l993. By the pricing modeL, we can explain the price of pre-sales houses was greater then that of existing housing in most cases. The results of our research also can be applied to the real estate policy and the decision of purchasing house.
