本研究之目的在於瞭解臺灣地區有關醫療需求與利用之行為，並進而藉其
研究結果來推估部分負擔之實施成效。針對「八十年家庭收支記帳調查」
之 1,327戶家庭之資料，本研究分別以多元迴歸之線性模型與指數模型來
從事分析，並獲致下列之重要結果及發現： 1.門診價格偏彈性為 -0.27
至 -0.28 之間；住院價格偏彈性為 -0.06之間。可見兩者均欠缺彈性，
且住院較門診的彈性值更小。 2.門診之住院交叉彈性為 0.0015 至
0.0016 之間，顯示門診與住院之間有些替代效果存在。 3.門診之所得偏
彈性係數為 0.19至 0.22之間，表示門診是種正常品，且其彈性值並不大
。 4.部分負擔在門診上所節省之保險給付，若以負擔率為 10%來看，約
佔保費收入之 6.6%至 10.2%；醫療給付之 8.2%至 24.9%。但若提高部分
負擔至 25%時，則上述各數值約增加為兩倍。可見部分負擔對於保險財務
之補充，實具有相當功效。 5.以 10% 至 25% 的門診部分負擔率來估算
，一般家庭於一年內須自付之門診費用，約佔家庭消費支出之 0.3%至
1.3%，佔儲蓄金額之0.7%至 3.0%，佔可支配所得之 0.2% 至 0.9%。其比
率並不算高，應不至於對一般家庭形成過重之經濟壓力。但若常使用醫療
資源的話，負擔將會更加提高且不容忽視。 / This research attempts to estimate the financial effects of
cost-sharing system in Taiwan's health insurance. According to
book-keeping data of 1,327 families, the study uses the linear
& exponential model of the multiple regression to analyze the
demand of the medical resources in Taiwan. The major results
are as following: 1. The partial price elasticity of the
outpatient care is esti- mated between -0.27 and -0.28, while
the partial price elasti- city of the inpatient care is -0.06.
Both are inelastic, but the inpatient care is ever more
inelastic than the outpatient care. 2. The cross elasticity of
the outpatient visits demanded with respect to inpatient price
is between 0.0015 and 0.0016. It shows that there are some
substitutions between two kinds of medical care. 3. The partial
income elasticity of the outpatient care is esti- mated between
0.19 and 0.22, which reveals that the outpatient care is a
normal good though the elasticity is small. 4. As to the
potential effect of cost-sharing system on saving outpatient
benefit, if the cost-sharing ratio were 10%, the reduced
payment as the share of the premium is expected from 6.6% to
10.2% and as the share of the medical benefit from 8.2% to
24.9% depending on varying assumptions. If the ratio were
raised to 25% , the reduced payment is projected to be twice as
above. It implies that the cost-sharing system could be
effective to improve the insurance finance. 5. It is further
estimated that, when the cost-sharing ratio of the outpatient
care were 25%, the cost-sharing burden for an average family is
1.3% with respect to the consumption expend- iture, 3.0% with
respect to the savings and 0.9% with respect to disposable
income. These ratios are not too high and an av- erage family
can afford it. However, for those using medical services more
heavily, their burden could be much higher and should be
seriously considered.
