| Summary: | 碩士 === 國立成功大學 === 政治經濟研究所 === 105 === The topic of this dissertation is about overpopulation. The main purpose of this dissertation is to answer “What is overpopulation?”
First, in the article, the author reviewed the evolvement of the notion of overpopulation in history and illustrated the contemporary meaning of overpopulation.
Next, in the article, the author conducted a deep research regarding Theory of Optimum Population. What’s more, the author extended the application of the theory to definite overpopulation and then demonstrated the three characteristics of theory of overpopulation: 1. The deterioration of average living standard, 2. The decrease of marginal output, 3. The increase of population suppression (population control).
Then, in the article, the author tried to use real cases to illustrate the corresponding social phenomena of these three characteristics of theory. The author picked up two historical cases (Chinese Qing Dynasty, The late period of European Middle Age). Both of them are classical and representative cases in relevant research field. From the analysis of the two cases, we could find that many social phenomena at that period live up to the characteristics of theory of overpopulation. All these social phenomena pointed to overpopulation.
Finally, in the article, the author inducted several observable social phenomena to embody the abstract notion of overpopulation. These social phenomena could be used to explain “What is overpopulation”. In other word, in the article, the author tried to find several observable social phenomenon as operating indicators, in order to distinguish overpopulation----when all of these phenomena emerge together, we could have sufficient proofs to infer that the society experiences the status of overpopulation.
