Many recommendations have been proposed to enhance the reform of public service bureaucracy. However, they were not effective enough since complaints were still directed toward public service practice. This research was conducted to investigate this issue and propose solutions to enhance the effectiveness of public service reform in the field of investment in order to increase regional economic growth. This research resulted in solutions in the form of an ideal reform model based on multi stakeholder (pentahelix) approach.
A hierarchical qualitative analysis approach was used in this research. This research also employed the phenomenological method through participatory observation. The focuses of this research included institutional conditions, human resources, bureaucratic procedures and multi-stakeholder involvement. The research was carried out in two stages. In the first stage focused on finding the most appropriate model of public service bureaucratic reform. Whereas, the second stage included the formulation of convincing pentahelix model to enhance the process of investment service reform.
