本論文為新的嘗試，研究台灣、南韓、新加坡三國，著重政治市場與威權政體間的關係，及其動態發展。每一國的政治市場都受到動態的內外政經結構情境的制約，其間的變遷關係，主要由國家的自主性決定。本論文使用政治市場的概念，並分別為獨占、寡占、壟斷性競爭與無市場等四種市場結構類型。市場結構假設政黨為行為者（廠商），選民為消費者，消費者購買商品以選票決定，廠商出盡各種招式，以新式產品來爭取消費者。
本文採取政治經濟學的研究途徑，歷史結構的分析觀點，並擷取國家與社會關係、政治市場的分析概念，在實質的分析層次上，政治市場的變遷與威權轉型之間的關係，可由政經勢力及選票席次結構來觀察。
獨占係指一股強大的政經勢力形成威權政治，該股政經勢力擁有國會席次70％以上。二元或三元寡占，係指政治市場內有兩股或三股主要的政經勢力，其擁有的席次和，加起來總計大於或等於90％以上。
本文所得的結論如下：台灣部分，戰後由一九四九年國民黨政府的黨國體制移入台灣後，（一）一九四九至一九六九年為無市場時期；（二）一九六九年至一九九二年為獨占時期；（三）一九九二年第二屆立法委員選舉之後，政治市場進入寡占時期。其間的威權形成、發展與轉型過程為循序漸進式的穩健型發展。南韓由戰後迄今，政治市場類型有三類，共可分為六個階段，為三國之中最複雜者，說明如下：（一）戰後的無市場期：一九四五至一九四八年為美國軍政時期；（二）第一、第二共和的寡占期：一九四八至一九六一年；（三）「四一九」之後的無市場時期一一九六一到一九六三年；（四）第三、第四共和「獨占到寡占之間擺盪」期，一九六三至一九七九年；（五）朴正熙遇刺後的無市場期，一九七九至一九八一年；（六）寡占期，一九八一年至今。南韓政治一大重要特徵為兩次軍事政變後，出現兩次的無市場期。新加坡的政治市場最為單純，分別為（一）寡占期，一九四六年至一九五九年自治政府成立，接受英國議會政治的遺緒；（二）一九五九年至今的獨占期，雖然選票結構已出現多元情形，但席次結構仍為獨占性質。

This study uses the research path of political economy, the
view point of historical structrue method, and the analytical
idea among country, social relationship, and political market.
We assume the structure of political market will verify the
numbers and relationship of political-economy power. The
formation and development of the authoritarian should be
reflected on the dynamic transition of political market. The
difference between the seats structure and vote structure will
show the quality of voting system and the strategy of the
ruling party. This study is based on the idea of political
market which is devided into four types of market, i.e.,
monopoly, oligopoly, monopolistic competition, and no-market.
From the practical level of analysis, the relationship
between transition of political market and authoritarian can
be observed by the structure of political-economic power and
seats of votes. Monopoly means authoritarian is formed by a
very strong political-economic power with more than 70% of
congress seats. Oligopoly means there are two or three
political-economic powers with a total seats more than 90%.
Since 1949 when KMT party move to Taiwan with party-state
system, the political market of Taiwan, shows: (a)no-market
from 1949 to 1969, (b)monopoly from 1969 to 1992, and (c)
oligopoly after the election of legislator since 1992. The
formation, development, and transition of authoritarian is
under a stable mode of incremental progress.
