摘要

本研究主要探討影響各縣市每人每日生活用水量之因素，以中華民國統計資訊網縣市重要統計指標中相關因素做為解釋變數，樣本分為非六都及六都兩部分各176筆資料，建立迴歸模型，探討各自變數對每人每日生活用水量之影響。由實證結果可知，模式中變數對生活用水量之影響大致與預期相符，可作為相關單位作為改善用水政策之參考。主要結論如下：
一.農林漁牧業就業者比例、每人每日垃圾清運量及大專及以上教育程度比例等變數對每人每日生活用水量為正向影響；表示農林漁牧業就業者比例、大專及以上教育程度比例愈大及每人每日垃圾清運量愈多，則每人每日生活用水量愈多。
二.自來水供水普及率及每戶平均人口數對每人每日生活用水量為負向影響；表示自來水供水普及率愈高及每戶平均人口數愈多，則每人每日生活用水量愈少。
三.非六都之每戶每人可支配所得對每人每日生活用水量為正向影響，表示非六都之每戶每人可支配所得愈高，其每人每日生活用水量也愈多。但在六都每戶每人可支配所得對每人每日生活用水量之迴歸結果為不顯著，亦即在六都，每戶每人可支配所得高低對每人每日生活用水量沒有影響。

The main purpose of this study is to investigate the factors affecting daily water use per person in various counties and cities, develop the regression model, and investigate the effect of various independent variables on daily water use per person. The main empirical results are as follows:

1.Variables, such as proportion of employment in agriculture, forestry, fishery, and animal husbandry industries, daily trash removal per person, and educational background of college and above, have a positive effect on daily water use per person, suggesting that the higher the proportion of employment in agriculture, forestry, fishery, and animal husbandry, the higher the proportion of educational background of college and above, and the higher the daily trash removal per person are, the higher the daily water use per person is.
2.The penetration rate of tap water supply and the average number of people per household have a negative effect on daily water use per person, suggesting that the higher the penetration rate of tap water supply and the higher the average number of people per household are, the lower the daily water use per person is.
3.Household Disposable Income per person in counties and cities other than Six Big Metropolises has a positive effect on daily water use per person, suggesting that the higher the household disposable income per person is, the higher the daily water use per person is. However, the regression result showed that the effect of household disposable income per person in Six Big Metropolises on daily water user per person did not reach significance. In other words, the household disposable income per person in Six Big Metropolises does not have any effect on daily water use per person.
