A crucial survey was conducted in Vietnam to ascertain the prioritized preferences of
willingness, a vital consideration for the construction sector that demands expertise,
resources, and effective coordination. This study aims to gauge the enthusiasm of
construction companies to enter the Vietnamese construction market. The research
methodology encompasses a literature review and expert interviews, which establish the
questionnaire's framework and hypotheses. The questionnaire covers three dimensions
with a total of 28 items. Using convenience sampling, 185 surveys were distributed to
qualified practitioners, yielding 52 valid responses—an effective sample recovery rate of
28%. The analysis highlights the significance of the “enterprise characteristics” aspect,
indicating that investment motivation is influenced by business traits. However, the
“national uncertainty” aspect, failing the t-test threshold of < 1.96, rejects the notion that
Vietnamese market and economic conditions impact investment willingness. Notably, the
“government policies” aspect indicates that policies from both nations significantly
influence investment willingness. The findings, compared to Taiwan’s current policies,
are notably favorable to practitioners.
