a major change taking place globally, especially in Southeast Asia which is one of the world’s fast growing regions in terms of population and urban growth The total population in Southeast Asia accounts for 14.64 per cents of Asia’s population Meanwhile, urbanization is also increasingly taking place in many cities in Southeast Asia Phnom Penh is the capital of Cambodia with an estimated population of 2.3 million by 2013, with the area of 678.46 square kilometers Recently, the development in the economy has impacts on the growth of Phnom Penh Capital The demand for more living spaces has increased so it lead to unplanned urbanization and industrialization in the outer periphery of Phnom Penh Capital, which, has created pressure on the change in land use pattern Therefore, it is important to study impacts of different factors on urban expansion However, the absence of data for Phnom Penh does not make a regression analysis possible Thus, the study employs available data of cities and provinces in Vietnam, a country which has a similar economic structure and level of development In this paper, the overall goals are to examine the change in population, GDP, agricultural investment and other that lead to the urban spatial growth and, the expansion of urbanized areas Based on the Monocentric model and panel analysis, the result shows that population, agricultural investment, industrialization and GDP are major pushing factors in the processing of urban expansion The analysis demonstrates the overwhelming importance of economic growth in the determination of urban land use This study examines the effect of economic growth on urbanization in Vietnam Based on this information, a case study analysis of Cambodia and Phnom Penh is also conducted Keywords: economic growth, monocentric model, urban expansion, land use ii Table of Contents ACKNOWLEDGEMENTS ABSTRACT LIST OF ABBREVIATION LIST OF TABLES LIST OF FIGURES Chapter :

areas to large cities Urbanization has had important consequences in many aspects of social, political, and economic life (Kleniewski & Thomas, 2011) Kleniewski, N., & Thomas, A R (2011) The world remained largely rural until the industrialization of the nineteenth century Urbanization is a major change taking place globally, especially in Southeast Asia Between the 1870s and World War II, a few dominant Southeast Asian urban centers such as Yangoon (Myanmar), Malaya (Singapore), Bangkok (Thailand), Saigon (Vietnam) and Manila (Philippines) were ports of Western and the gateways that connected the frontier southeast Asia to the global economy (Gregg Huff, 2012) The study of urbanization is very necessary for developing countries because these countries are in the process of facing with rapid urbanization Urbanization is the process which leads to a higher proportion of total population of an area living in cities and towns and generally occurs with modernization and industrialization Moreover, modernization and industrialization pull people to cities at the same time that they push people from rural home And when more and more people leave villages and farms to live in cities, it is the results of urban growth According to experiences of most part of the world, urbanization is part of the development process Rapid urbanization is closely linked to economic development that is contributed with the rising demand of land in manufacturing and service sector in urban and the decline of agricultural land in rural Urbanization occurs as countries shift from rural agricultural activities into urban industrial activities Successful urbanization requires the expansion of the industrial and service sector (Parker, 1996) Similarly, urban expansion mainly depends upon the urban requirement, facilities available and industrialization The development of cities plays a very important role in economic development in developing countries The major dynamic driving forces of cities in developing countries are economic and social http://2012books.lardbucket.org/books/a-primer-on-social-problems/s17-01-a-brief-historyof-urbanizatio.html CHATER 7: DISCUSSION 7.1 Explanation of the difference between theory and my analysis After my analysis, I observe that the result of my analysis is consistent with Monocentric theory condition except the agricultural rent In my model, agricultural rent is replaced by agricultural investment (Wei.1993, Deng et al 2008) It means that when the agricultural investment increases, more land will be urbanized It is different from the theory of monocentric city which predicts that less land will be urbanized I think this is because speculation of agricultural land takes place in Vietnam; people still buy more agricultural land to urbanize it Here agricultural investment is the investment in agricultural land by construction infrastructures and so on for convert agricultural land into urban land 7.2 Limitation of this analysis Although this thesis reaches several new findings, it also has several limitations in assumptions, methods, dataset and discussions  Limitations of assumptions The study assumes the same definition of urban expansion land This assumption is not really exactly like that in real life In fact, implementation of Monocentric model in 13 urban economics and verify with conditions And many of researchers found some points different from the assumption In reality, we cannot identify which part of the city is the center of business district (CBD) In addition, there are more factors that push the urban expansion land  Limitations of method It is very clearly that the empirical researches have used methods to estimate the effect of the economic growth on urban expansion land such as OLS, First –Difference model (fixed effect model) However, based on the nature of dataset and the goals of research, this study uses only one of these methods that is fixed effect method and does not apply other methods 13 See page 15 46 Based on the monocentric model and empirical researches and the nature of dataset, the research just applies the log linear form on some variables except service and industrialization variables  Limitations of dataset First, the study covers 63 selected cities and provinces of Vietnam, because of lack of dataset I decide to drop three provinces including Hoa Binh, Hau Giang,Lai Chau from my analysis Second, the study just considers one kind of measure independent variable urban land use that it is from the sum of housing land and non-agricultural land use and does not covers all the 26 kinds of land use in Vietnam Third, the dataset sample just takes into account 11 years period from 2000 to 2011 and unbalanced panel data The result from my regression is not surely correct because of the missing of data in my analysis Fourth, urban expansion in cities and in provinces happens in different periods of time, which makes my estimation not accurate Fifth, the study does not separate the region of country There are regions in Vietnam By using fixed effect model, the result of this analysis is omitted all dummy variables Therefore, it is impossible to conclude which one of cities and provinces tends to be urbanized  Limitations of discussion Even though, the study has mentioned about the monocentric model, finding and discussion of number of researches in regional and urban economics, it cannot cover really abundant evidences from urban studies and urban expansion studies 47 CHAPTER 8: CONCLUSION Urbanization has an important role to play in developing countries on economic development of any nation such as Vietnam and Cambodia This paper demonstrates the effect of economic growth on urbanization in Vietnam This study focuses on the close relation between urban land expansion and economic growth Following this empirical analysis study, it shows that population GDP, and agricultural investments have positive effects on urban land expansion in Vietnam To investigate the determinant of Vietnam’s urban land expansion, this paper has estimated from the empirical study The dependent variables (sum of residential land and non agricultural land) of empirical study and taken all data such as GDP, population, agricultural investment (sum of all budget investment project every year) ,industrialization (GDP1_share) and service sector (GDP2_share) for all provinces expect Hoa Binh, Hau Giang ,Lai Chau because of the missing data The empirical estimates use annual data from 2000 to 2011 By using result from the fixed effect method, this paper demonstrates the powerful role that population has played in Vietnam’s economy including urban expansion in each cities and provinces It shows that people move from rural to urban area increasingly In developing countries, population is growing faster in urban areas Moreover, regardless of empirical approach I also found that the role of the other factors such as GDP and agricultural investment are relatively small in Vietnam It means that GDP and agricultural investment have fewer effects on urban expansion If my result is correct, this suggests that if Vietnam continues to expansion urban land, Vietnam have to increase the rate of GDP growth, more agricultural investment because they are major factors that push the urban land expansion In 2025, Vietnam expects to become a middle income country and 50 per cent urbanized In a case study of Phnom Penh Capital, I believe that the result of analysis in Phnom Penh will be similar to Vietnam Because of Vietnam and Cambodia are in the process of facing rapid urbanization and both countries have a similar level of economics Following this empirical study of Vietnam, I think that Cambodia will get profit from urbanization but not much because my country still have a lot poor urban and low income people In the future, Phnom Penh will develop if we can increase the growth 48 of GDP every year and government should increase the investment in agriculture: because economic growth contributes in the processing of Urbanization in Phnom Penh It will give more and more profit for all people in Phnom Penh and also people living in Cambodia Meanwhile, Setting up the satellite cities, skyscraper and residential in Phnom Penh will push the GDP growth, population growth and urban expansion land Moreover, new urban areas will give Cambodian people a better way of living in the future In the near future, I think that Phnom Penh will become a small metropolitan in Asia 49 REFERENCES Alonso,W.(1964) Location and Land Use Cambridge, MA: Harvard University Press Anas, A & Kim, I 1996, 'General Equilibrium Models of Polycentric Urban Land Use with
