A 1996 study by Huang Wan-tran, an expert in agricultural economics at Changhua's Chung Chou Institute of Technology, showed that Pingtung's growers were Taiwan's most profitable, raking in NT $ 450,000 per hectare (including wages paid to family members) at the height of the betel-nut craze. Even Kaohsiung's growers, who did the least well, generated revenues of more than NT $ 300,000 per hectare in those days.
根據彰化中洲技術學院農經學者黃萬傳在 1996 年台灣檳榔最風光時所做的研究顯示，當時全台檳榔收益最佳的屏東，每公頃一年淨收入 45 萬元（未扣除自家勞力工資）；即便收益最差的高雄縣，一公頃也有三十多萬元。
