The Sunflower Student Movement was a significant event in Taiwan’s political history. Contrary to the conventional wisdom, we argue that the effect of the movement on the attitude of the general public, particularly the young, toward the cross-Strait economic interactions and the perception that Taiwan may be forced to make political concessions resulting from such ties is limited. Based on the Taiwan National Security surveys, we find out that the movement, to a certain extent, reflected public sentiment already existing in the society, and did not push the sentiment further. Compared to the attitude toward national identity, which is more long-lasting, the views on the cross-Strait economic ties may be more volatile, and are thus less predictable.
