Furthermore, manufacturing is the link in the industrial chain which yields the lowest profits. For example, the race between Taiwan's major semiconductor makers over the last two years to invest in new plant has already led to excess capacity and diminishing returns on investment.
而生產製造是產業環節中利潤偏低的一環，譬如近兩年來，台灣各大半導體廠商爭相鉅額投資、產能過剩的結果，已出現邊際效應遞減（投資第一個一百元可以賺二十元，投資第二個一百元只能賺十八元……）的後遺症。
