本研究以1991~2016年之年資料,探討影響台灣機車內銷量之因素,使用市區客運人數、每人GDP、人口數、汽車內銷量為自變數,研究結果顯示,市區客運人數的迴歸結果為正向顯著,表示市區客運人數越多,大眾運輸越發達,機車內銷量會降低。平均每人GDP的迴歸結果為正向顯著,但人口數的迴歸結果則為負向顯著,而汽車內銷量的迴歸結果並不顯著。 由此可知要解決都市地區機車擁擠的問題,一味提高機車停車格的收費並不可行,必須發展公共運輸疏導通勤人口,提高公共運輸市占率。因此政府未來應持續推動各項公共運輸發展方案,並依各縣市政府地域特性及使用公共運輸的普及性,請相關縣市政府逐步規劃促使民眾轉移使用公共運輸工具之具體作為及配套措施,同時也宣導民眾多搭乘公共運輸工具。
In this study, the data from 1991 to 2016 are used to explore the factors affecting the motorcycle sales volume in Taiwan, such as the number of passengers of city bus, GDP per capita and total population number with the motorcycle sales volume as the independent variable. The study results show that the regression result of the number of passengers of city bus is significantly positive, indicating that the mass transportation is more developed in the case of bigger number of passengers of city bus, while the motorcycle sales volume would be reduced along with the mass transportation development. The regression result of the GDP per capita is significantly positive; the regression result of the total population number is significantly negative; and the regression result of the motorcycle sales volume is not significant. It can thus be known that it is not feasible to solve the motorcycle congestion problem in urban areas simply by raising the fees of motorcycle parking lots and the public transportation must be developed to divert the traffic of commute population and increase the market occupancy of the public transportation. To this end, the government should continue to promote various public transportation development schemes and call on the public to take public transportation means in the future.
