In fact, there's a quite big difference in the scale of the markets on the two sides. For example, the mainland can do something like allow 15 kinds of fruit from Taiwan to be imported tariff-free, and then cut the domestic tax in half, but we can't, and we don't have to. Why?
事實上，兩岸市場規模是差蠻遠的，例如大陸可以開放台灣 15 種水果免關稅進口，然後內地稅減半，我們做不到，也不必做，為什麼？
