This study is designed to analyze the influence of industrial park (IP) development on the lives of people living around the IPs in Vietnam and on new livelihood strategies for people after the industrial park was built and developed. Data were collected from a survey of 409 people living around industrial parks in three regions of Vietnam (Northern, Central, and South Vietnam). The findings show that the livelihood resources, such as financial resources, physical resources, social resources, and natural resources, have a positive relationship with people’s livelihoods after industrial park construction and development; though, the degree of influence of these resources is different. Whereas human resources have a positive effect (through the item – additional jobs created by the industrial park) and a negative effect on income (through the object – the unemployed labor by the industrial park built and developed). The findings also show that most households surveyed responded that their lives had changed for the better (about 41.36% compared to nearly 28.91% of households surveyed who said their income had decreased).
