Brunei Darussalam is a country located in the southeast and island of Borneo, it is one of ASEAN countries. The main industry in Brunei is an oil and gas industry. The book describes some factors of entrepreneurship in Brunei Darussalam. Brunei has a vision called "WAWASAN Brunei 2035." As the government mentioned that Brunei expected to be one of the best hubs of entrepreneurship in ASEAN countries. The Bruneian government is working very hard to encourage the Bruneian entrepreneurs to innovate something new. The research explains and discusses some of the factors of the entrepreneurship and its effect in Brunei Darussalam. It is worthful if I mentioned that the same design of this research could be applied somewhere else with increasing the ability of the research.
