違章建築現象分類與其對外部環境衝擊之研究- 以台南市為例A Study on the Classification and Environmental Impact of Building Violations - Using Tainan City as an Example
Building violations are one of the most important issues for the building authorities of all local governments. These authorities must cope with such building management violations. Based on reported building violations in Tainan City, we classified the cases using time and space dimensions for the analysis and comparison of the features and the impact for each kind of building violation. Externality theory was employed to investigate the gap between legal building usage as defined by related laws and practical building usage as per the users’ view. A questionnaire survey was conducted to understand residents’ needs for space usage. Based on the survey results, we analyzed the reasonability of the current laws and regulations governing building and space management. We then proposed building management strategies based on this analysis. Finally, a hedonic price model for illegal buildings was established using this method that examined the substantial effects of different building management strategies to find future directions for handling building violations.
Key words: building violations, environmental externality, hedonic price, Tainan city
