隨著科技進步,衡量經濟發展的方式也日新月異,用衛星照片觀察一地區的燈光亮度,以表彰某地區之真實經濟情況,即為現下常用的方法之一。另中國經濟自改革開放以來,成長飛快,近年來更是帶動全球經濟成長的要角。本研究以中國2003年至2015年之244個地級市及4個直轄市為樣本,觀察官方公布之GDP、李克強指數中貸款量及用電量與衛星燈光亮度間的關係,藉以衡量GDP、貸款量及用電量與真實經濟發展間是否顯著相關。 結果發現,中國之人均GDP之絕對數值或年增率,較能反映中國經濟的狀況及變化,而人均貸款及人均用電量之絕對數值即便也能觀察中國經濟的狀況,但效果不像人均GDP穩定;而觀察人均貸款及用電量之年增率,較難察覺中國經濟狀況的變化。
It`s objective to discover regional economy by interpreting the night lights data from the outer space. This research will discuss the association of the night lights data with GDP, loans and electricity consumption by 4 special municipalities and 244 prefecture-level cities from 2003 to 2015. By observing the “night lights” data, it is more effective to reflect China economy in terms of GDP per capita and it`s growth. But by using the same “night lights” mechanism, there is no sufficient evidence to prove that loans and electricity consumption per capita can illustrate China economic status.
