STATEMENT Public investment and its role in economic development have been affirmed by many economists and policy makers In developed or developing countries, public expenditure in investment is considered as a foundation in long run economic growth (Tanzi and Zee, 1997) According to Cashion (1995), Kocherlakota and Yi (1997), Fuente (1997) and Kneller et al., (1999) public investment has positive effects on economic growth, especially in the case of developing countries (cite in Kneller R and Haque M E., 2008) However, a positive impact of public investment depended on institution It was found that a better institutional setting may foster the positive effects of public investment (de la Croix and Delavallade, 2009; Dort et al., 2014) While a poor institution, especially corruption, waste is popular (Tanzi and Davoodi, 2002b) Firstly, corruption impacts the public investment in both quantity and quality There is a wide spread of corruption on over the world, especially in developing countries in the recent years From its detrimental impact on economic growth, corruption distorts decision of higher political, retards economic growth (Tanzi, 1998) Heath W (2000) stated that: “corruption is a cancer in society and is slowly eating away at the public sector” It reduces the return in public investment, lead to the economic development down following by Kneller R and Haque M E (2008) In conclusion, through the impact on the public investment, corruption retards the economic development Vietnam is a developing country in Southeast Asia with over 90 million inhabitants By political and economic reforms (Doi Moi) launched in 1986, Vietnam’s GDP per capita increase from around 100$ to over 2000$ by the end of 2014 within a quarter of a century In reducing poverty, Vietnam has a dramatic change in which the number of people dropped from over 50% in the early 1990s to 3% today (World Bank, 2015) With the development of two big cities is Ha Noi and Ho Chi Minh, Vietnam inherited the contribution of 63 provinces in the process of its own economic development The GDP of Ha Noi and Ho Chi Minh account for 10.3% and 20% of the GDP of whole country H5: The foreign corruption has a negative effect on corruption In Table 4.5, the foreign capital investment has a positive and significant effect on the informal cost (significant at level 1%) That means when get more foreign investment, corruption has a dramatic drop This result is consistent with Ades and Di Tella (1999) One of prerequisite thing contributed in this is international law When attending in the economy of Vietnam, they tend to find an open market which is not only professional but also must accept the law This thing acquires a big change of anti-corruption define in bureaucrat system 37 CHAPTER CONCLUSION AND SUGGESTION This section briefly summarizes the methodological approach, major findings, and policy implications, as well as suggestions in some directions for further research 5.1 CONCLUSION The main purpose of this paper is to explore the impact of corruption in the relationship between public investment and growth Firstly, the methodological approaches in this study are: i) The model of the simultaneous equation system was built on the link between the GDP per capita growth, public spending in investment and informal cost; ii) Three stage least squares (TSLS) method was employed to find this connection; ii) The descriptive data analysis is prefer using for getting the overview in data Overall, the finding in this study is consistent with research hypotheses The various relationships among corruption, public expenditure in investment, economic growth, as well as the others were found The findings are: i) When corruption reduces, public expenditure in investment reduce; ii) When corruption reduces, there is a positive impact on the economic growth; iii) The presence of corruption does not have impact to public expenditure in investment, and this spending has a positive effect to economic growth; iv) When corruption drops, private investment increases; v) A rise in foreign investment has a positive effect on reducing corruption 5.2 POLICY IMPLICATIONS After having an overview of this research, it is indicated that the role of public investment is important It is not only for each province but also for the whole country Actually, the efficiency in this investment activity has been creating for Vietnam and each province in particular a new foundation on the integration road with the world Thus, it is necessary in strengthen this investment Nevertheless, the most concern is corruption in this activity, although its impact in this study is insignificant In fact, the government of Vietnam has been complied two laws: the anti-corruption law (effective in 2006, January 1) and the public investment law (effective in 2015, January 1) This thing also indicates that a big 38 concern of government about corruption Because of this, an enhancing in anti-corruption in bureaucrat system becomes more important than ever Getting a drop in corruption, Vietnam will get more achievement in the development process In order to that, firstly, administrators of Vietnam and province in particular need to become an exemplary model in fighting corruption In term of integration process with the world of Vietnam, the openness policy gets more important Attracting more foreign investments, Vietnam as well as 63 provinces/cities will have a chance for decreasing corruption 5.3 SUGGESTIONS FOR FURTHER RESEARCHS With the time is short from 2008 to 2013, together with the limited in data, this study only find the trend in this impact In further study, we suggested to regress with more valuable methods and run with a lag variable of public investment to find out the margin coefficient in the result Furthermore, to investigate in the economic growth, some valid control variables should be considered in this study such as the labor skills, as well as the leadership capacity of the government or the quality infrastructure index Especially, having a study to build a set of indicators on corruption of 63 provinces/cities in Vietnam bring a great significant not only for policy makers but also for the development of a whole economy, Vietnam 5.4.THE LIMITTED OF THESIS This section lists some limitations of this study In fact, this study approaches the informal cost “chi phi khong chinh thuc” in the PCI index to indicate the corruption variable for 63 provinces/cities It is a limitation When “chi phi khong chinh thuc” is only showed a part of corruption activities; that is a type of bribery during business registration and licensing from a survey on firms of VCCI survey on each province 39 Moreover, the source of province data was only accessed from Provincial Statistic Yearbook and statistic office of each province There is still not having an assessment agency responsible for quality of this data Finally, in reality, public spending in investment needs a long time to complete a project, so the use of lag variable is necessary Because of the limitation in time, this approach will be presented in a further research 40 REFERENCE Ades, A., & Di Tella, R (1999) Rents, competition, and corruption American economic review, 982-993 Anh, T P T (2008) Chi tiêu phủ tăng trưởng kinh tế:

Land access and tenure security; Transparency; Time costs of regulatory compliance; Informal charges; Proactivity of the provincial government; Business support 48 services; Labor training; and Legal institutions Sub-indices are constructed for each of these components and then combined to provide an overall indication of the quality of economic governance The sub-indices include both perception-based and concrete indicators The questionnaire was designed to have name and position of respondent usually by the ownbusiness experience That made to increase confident for this survey (For full details of the construction of the PCI, see www.pcivietnam.org) The informal charge is one of nine indicators of this data It was surveyed regard on bribery during business registration and licensing 49 APPENDIX 6: Table A.5: The ranking of 63 provinces/cities in the PCI index in the period from 2008 to 2014 PCI RANKING (TOP) Da Nang Vinh Phuc Vinh Long Dong Thap Long An PCI 2010 PCI 2011 PCI 2013 PCI 2012 PCI 2014 72.18 Da Nang 75.96 Da Nang 69.77 Lao Cai 73.53 Dong Thap 63.79 Da Nang 66.45 Da Nang 66.87 71.76 Binh Duong 74.01 Lao Cai 67.95 Bac Ninh 67.27 An Giang 63.42 Thua Thien Hue 65.56 Dong Thap 65.28 70.47 Dong Thap 67.22 Long An 67.12 Lao Cao 63.08 Kien Giang 63.55 Lao Cai 64.67 68.54 Tra Vinh 65.80 Dong Thap 67.06 Binh Dinh 63.06 Quang Ninh 63.51 Tp.HCM 62.73 67.24 Binh Duong 65.72 Da Nang 66.98 Vinh Long 62.97 Dong Thap 63.35 Quang Ninh 62.16 66.65 Bac Ninh 64.48 BRVT 66.13 Kien Giang 62.96 Ben Tre 62.78 Vinh Phuc 61.81 Binh Duong PCI 2009 PCI 2008 69.37 66.97 66.64 63.99 Lao Cai Dong Thap Vinh Long Vinh Phuc Sources: PCI Report (2008-2014) 50 51 ...
