structure on average is earned income which is one of the main drivers to improve the living standard of most Vietnamese households in recent years However, there is an increasing tendency of income inequality and living standards' difference between regions, rural and urban areas as well as between the richest and poorest households This paper contributes to the understanding of the effects of Region-level characteristics, Community-level characteristics and Household and individual characteristics on household's earned income The determinants of earned income are considered at household, commune and regional levels While wage employment still constitutes I the backbone of the urban economy, non-farm activities and income diversification are increasingly significant for rural households It is recognized that households' physical capital (housing), human capital (education), and local infrastructure are ~ignificant determinants in increasing their earned income Key Words:

Vietnam's other international institutions and partners have been recognizing the significant results in the execution of the Millennium Development Goals (MDG) and the poverty reduction program in Vietnam The goal number on reducing the percentage of poor and hungry households is the most vital and critical foundation for the successful implementation of other MDG For better integration into Vietnam's national and provincial socio-economic development strategies and programs, eight MDGs have been translated into Vietnam Development Goals (VDG) (see appendix 1) to bring them closer to the country's situation 1.1 Problem statement As one of the poorest countries in the world 25 years ago, Vietnam proudly became a lower middle income country with per capita income of$1,130 in the end of2010 and the poverty rate at national poverty line has dropped remarkably from 58.1 percent to 14.5 as figure 1.1 below Five ofMDG targets has already achieved and most of social welfare indicators have been improved, thus Vietnam is making progress in attaining two more targets by 2015 (World Bank, 2008) Figure 1.1: Vietnam poverty headcount ratio at national poverty line 16 ! 12 0~ ~ ~ ~ ~ / ~ ~ # ~ # ~ F Year Source: World Bank (2008) ~ ~ ~ ~ ~ # Nevertheless, policy makers have realized that results of some poverty reduction programs are not sustainable because the ratio of household falling back under the pbverty line remains high, especially in some rural and remote areas I Moreover, I there is very high rate of household closely above the poverty line in accordance with the new poverty criterion Since early 2008, Vietnam has faced some economic difficulties due to the global financial crisis, thus many new obstacles rise from the present poverty reduction programs Consequently, the government has to consider how to reach a more balanced achievement in all of VDG, economic regions and social communities to improve the sustainable development In another word, rural poverty reduction must be evaluated as an effectiveness measure and a vital section of any poverty reduction strategy, as well as rural development policy Any policy that focused on subsidy package was already proved as band - aid solution having less impact on sustainable rural development and its resources should be diverted to pro-poor policy Every government's pro-poor policy, directly or indirectly, seeks to create employment opportunities for the poor or improve productivity and earning capability on a sustainable basis, especially in the sectors employing most of the poor Both elements raise the incomes of the poor and hence speed up the pace of poverty reduction The strategies which households often use to strengthen income have been a topic for research in recent times (Ellis, 2000) Studies on rural income growth suggests that diversification of income sources is a key strategy which individuals and households use to strengthen their income sources and thus this way reduces poverty (Minot et al 2006) Among the sources of households' income, earned income (comprising wages or salary and net revenue from both agricultural and non-agricultural self-employment) is the most important component of sustainable development and engine to higher living standards However, there is an increasing I Rural area is "a local community with a population density below 150 habitants/ km2 (500 in the case of Japan) Typology of regions according to the share of rural population: "predominantly rural" = more than 50%; "significantly rural"= I5-50%; "predominantly urbanized"= below 15%" (OECD, 1994) "' access of the poor to markets Physical isolation caused by remoteness and poor infrastructure reduces economic opportunities, and makes access to markets, basic social services, credit, information and mass media more difficult Poor infrastructure creates major obstacles for agricultural diversification and results in the underdevelopment of off- farm activities Good infrastructure is also crucial for improving the welfare of the poor in many other economic and social aspects, such as nutrition, health, literacy, political and social exclusion, and vulnerability Third, education is a vital driving force in boosting income, particularly at the college level This emerges clearly from my research, although the analysis is based on households rather than individuals With more education, adults are more likely to be working, and tend to earn more However, the most efficient solution is developing local human resources through vocational training for the poor households who had to work very early without going to school Policies to enhance the human capital of the poor through providing basic services such as health care, clean water, education, training and retraining, and technology transfer through agricultural extension activities so that the poor have knowledge, intellectual and physical capability to seize opportunities from economic reforms Education and training to acquire necessary skills, and general and functional knowledge usually provide good opportunities of securing stable jobs, and understanding and applying new techniques Education also helps households take advantage of other infrastructure services such as irrigation, communication, electricity and transport Better health care will improve health status of the poor, which in its tum will reduce the costs incurred by illness and diminish the risk of loss of earnings Fourth, agriculture is main source of earned income for rural area, so policy should be focused on forming business support center, and enhancing research & development institutes to popularize new skills and technologies Policies to promote research and development, especially in agriculture, can significantly raise productivity because higher agriculture outputs will result in higher farmers' earnings, lower goods price to consumers, and more wages in non-farm sector 59 • Moreover, it is recommended to improve the "competitiveness" of rural areas by developing and commercializing natural and cultural advantage, specifically tourism closely accompanied by friendly services, and local handicraft operations Finally, ethnicity is correlated with earning Chinese and Kinh households are better off than the rest of our society, while other ethnic minorities are noticeably poorer than society at large, although this appears to be due to low educational levels and remoteness than to ethnicity A special targeted program for ethnic minority development is needed to help upland people and ethnic minorities to escape from poverty People belonging to ethnic minorities often face not only physical, but also social isolation from the world outside their community This isolation is associated to a significant extent with their linguistic, cultural and educational differences as well as differences in cultivation practices These impede their interaction with the civilized world, and limit their access to new information, improved techniques and ideas Again, the regional dimension should be accorded with greater importance in both macro- and household- level policies There is a trade-off in resource allocation between areas with the highest financial returns and those with the greatest needs Evidence from many countries suggests that resource allocation under pro-poor policies should be directed more towards poorer regions with greater needs, rather than serving to reinforce current regional disparities 5.2 Limitations My paper could be extended and get deeper because of the following reasons: First, the limitation of using current cross-sectional data of VHLSS 2008 in linear regression definitely proposes weaker conclusions than using panel data With panel data, I could find not only relationship between characteristics-related variables and earned income, but also verify the causal effects as well as control other unobservable factors Second, Vietnam is a developing country with low productivity, so significant difference in working hours and mean salary are the major reasons of income gap 60 between to top and bottom quintiles My paper can be enhanced its in-depth study by examining the components of earned income per capita, such as earning per hour, the amount of hours worked per household member, and the share of the working household members Third, social capital is an important asset of household as described in the conceptual framework for livelihoods analysis However, the impact of social capital cannot be determined by this paper Four, it should be noticed that in last three months of2008, the government or other organizations implemented projects or programs in approximately 80% of rural communes to enhance population living14 However, my paper cannot point out the effect of such government intervention and programs Finally, agriculture is still an important source of income to improve household livelihood The VHLSS 2008 reports that the main income source of 97.2% surveyed communes are from agriculture, while the North West and the Central Highlands regions both have agriculture income absolutely in all surveyed communes As survey result, most households 87% of communes acknowledge that the first reason of their living standards' improvement was increase in farm income In addition, efficiency of cultivation methods, expanding of irrigated agricultural areas and marketing of high-yield agricultural product are vital sources of crop productivity In short, agriculture is still playing a vital role in promoting rural livelihood and should be an area for further research 14 "Projects or programs of the Government or of other organizations: Hunger alleviation and poverty reduction (72% of communes), economic and infrastructure development (70% of communes), job creation (34% of communes), culture and education (31% of
