Peng chose to resign because of controversy over a provision banning house-construction on newly purchased farmland, part of the Agricultural Development Act Amendment Bill, which was due for reading in the Legislative Yuan. The legislature's pro-farming faction remained staunchly opposed to the provision, and the KMT's policy committee had already drafted a "caucus version" of the amendment, allowing for houses to be built on newly acquired farmland.
引發彭作奎辭職的原因，在於行政院「農業發展條例修正草案」即將送進立法院審查，草案中針對「新購農地不得興建農舍」的規定，卻仍無法得到各方支持，除立法院老農派立委表示將反對到底，國民黨政策會亦已提出「黨版」農發條例，將同意新購農地得以興建農舍。
