摘要

本文為釐清生產基礎與消費基礎衡量之二氧化碳排放之差異，作為未來認定台灣對全球二氧化碳排放貢獻之參考，並利用計量方法評估總體經濟變數的單根與共整合檢定，推導出生產與消費基礎之環境顧志耐曲線趨勢(1992年~2006年)。本研究獲得結論如下：(1)以消費基礎計算的二氧化碳排放量，將可大幅降低台灣的減量責任；(2)台灣出口的能源密集度相對高於進口能源密集度，是解釋消費基礎計算之二氧化碳排放量低於生產面基礎計算之二氧化碳排放量的主要原因；(3)台灣貿易活動之全球溫室氣體排放淨貢獻為負；(4)消費面計算之EKC斜率低於生產面EKC斜率，隱含消費面計算之二氧化碳將更早於生產面計算之二氧化碳達到脫鉤狀態。

The Purpose of this article is to clarify the basis of production and consumption based on measurement of the difference in carbon dioxide emissions, which can be identified the responsibility to global carbon dioxide emissions in Taiwan. In this study, measurement methods to evaluate the overall economic variables of unit root and co-integration, and deduced the basis of production and consumption of environmental Kuznets Curve (1992~2006).
The analysis result as follows: (1) no matter the emissions of carbon dioxide or the carbon intensity, the consumption based computation carbon dioxide emissions is lower than production based computation, (2) there are negative CO2 emission contribution to the world in Taiwan’s net export activities, (3) The slope of EKC of consumption baes is less than production baes EKC which means consumption baes EKC is becoming relative decoupling in Taiwan.
