台灣各縣市固體廢棄物回收率之影響因子探討

Factors of the Solid Waste Recycling Performance in Taiwan's Administrative Regions

摘要


本研究探討台灣自1997年開始實施資源回收四合一計畫以來,影響各縣市資源回收率的因素,並以2001到2009年各縣市的資源回收率、回收資源量、回收資源種類人均量、教育水準、人均可支配所得、勞動力參與率、縣市行政區別與政府資源回收政策等因素,進行縱橫面資料迴歸(固定效果)分析。研究發現,影響整體資源回收率的因子通常也是影響各類回收資源項目的主要因素,亦即無論是以資源回收率、人均回收量、各類回收資源人均回收量做為績效指標,具有高教育水準、高可支配所得特性的縣市,其資源回收的效果也愈明顯。而環保資源的投入,如平均每人環保經費、人均環保稽查次數等,對資源回收似未產生正向效果。此外,研究發現各縣市先天地理差異與後天經濟發展的差異也會影響各類資源回收成效。另發現2006至2009年期間全面實施的強制垃圾分類政策,高教育水準人口對垃圾強制分類政策的實施有較明顯的配合效果,正面增強資源回收效果。

並列摘要


This study analyzes the factors of solid waste recycling in Taiwan's administrative regions that implemented the 4-in-1 Resources RecyclingPlan since 1997. The panel data regression approach is applied for empirical study. The panel data from 23 Taiwan's administrative regions data in the period 2001-2009 are retrieved, including recycling rate, recycling weight per capita, education-level, disposable income, labor force participation rate, city/county, and government environmental policy variables. There are significantly higher recycling volumes or weights with respect to iron can, old clothes, household appliances, scrap aluminum foil bags, and paper containers, due to the active local recycling agents. Especially, the local recycling job opportunities significantly help reduce the unemployment rate. Higher education and disposable income levels also significantly promote regional recycling performance.
