firms having ep positive R&D, which was drawn from the data set of Vietnam Enterprise Survey n w conducted by the General Statistics Office in 2004, is used for analysis A regression lo model is estimated based on the Cobb-Douglas production function and the R&D ad capital model with three main independent variables: physical capital, labor and R&D u yj th capital, and dummy variables reflecting type of ownership and size of labor p yi la R&D capital is measured in a simple way by using available R&D expenditure in the lu an survey and ignoring the accumulation of R&D expenditure in the past, its deflation va and obsolescence However, a positive and significant impact of R&D expenditure on i n fu productivity is found with the elasticity of productivity with respect to R&D m ll expenditure per labor is about 0.1 Moreover, the effects of physical capital and labor oi on productivity are also positively and statistically significant The elasticities of nh at productivity with respect to physical capital per labor and total labor are around 0.35 z z and 0.15, respectively ht vb k jm om l.c gm an Lu n va te re

CHAPTER! INTRODUCTION ng hi RATIONALE OF THE RESEARCH ep 1.1 n w In the modem economy today, technological progress has a quite central role It lo contributes importantly to growth of economy and is a key factor to determine the ad competitiveness of firms in both national and international marketplace Research and u yj th Development (R&D) is widely regarded as the core of technological advance, and yi innovative capacity of firms are reliably indicated by levels and rates of R&D pl ua al expenditures growth Countries belonging to the Organization for Economic Cooperation and Development (OECD) spend significant amounts on R&D activities n n va On average, OECD countries have spent more than percent of GDP on annual fu public and private R&D investments during the last two decades (OSTP , 1997) oi m ll nh In a traditional way, firms have paid attention to R&D because the technical advances at resulting from innovation may allow them to improve productivity, succeed in z z competitive markets, and meet environmental and regulatory requirements Besides, vb R&D has also had contribution to the development of new products and, in many ht k jm cases, the creation of new markets Within firms, economic returns are always taken gm into consideration on deciding the importance and nature of R&D performance Firms l.c usually take part in R&D activities only when the results are appropriate and offer om higher rates of return than that of other available investment alternatives such as Lu acquisition of new machinery, advertising, or purchase of speculative assets an OSTP is Office of Science and Technology Policy (Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam te of knowledge This stock of knowledge can be increased by formal investment in re enhancing productivity growth which is widely acknowledged is increasing the stock n va There are many sources for productivity improvements, but one strategy for (Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam(Luận.văn).impact.of.rd.on.the.productivity.growth.of.manufacturing.firms.in.vietnam R&D activities In the private and public sectors, the allocation of resources toward the investment to generate new knowledge must be decided carefully ng hi In spite of the importance of R&D in firms' productivity, R&D activities have not ep been taken into consideration for much investment in Vietnam, especially in business sector While most OECD countries and China devoted around 2% of their GDP to w n R&D activities, Vietnam spent only 0.5% of its GDP for this purpose (Nguyen and lo ad Tran, n.d.) R&D expenditure of Vietnamese enterprises accounted for only about u yj th 20% of the total R&D expenditure of the country in 2002 (Nguyen, n.d.) Whereas, yi according to OSTP (1997), companies in OECD countries finance more than 50% of pl all R&D expenditure and they conduct two-thirds of all R&D activities SMEs make ua al up the vast majority of registered companies in Vietnam, namely 96.5% n va Nevertheless, the technology level across the SME sector in Vietnam is generally n assessed as being two, three or even more times lower than both world and regional fu oi m ll levels (Bezanson et al., 2000) nh One of main reasons under the assessment of the Ministry of Industry is that the labor at z currently lack of necessary skills to support technological upgrading and there are z ht vb very little R&D activities appropriate for such upgrading Indeed, only a small jm fraction of the country's R&D scientists and engineers are working in industrial k enterprises The rest are working in national centers for R&D, ministries and gm government agencies, universities or other institutions that perform research Another l.c reason is that there is little market-oriented relationship between firms, R&D om institutions and universities (Bezanson et al., 2000) Moreover, the most important Lu va their limitations in financial resources an reason for a little investment in R&D activities of Vietnamese enterprises may be n has emphasized the role of technological or knowledge capital in productivity growth Early studies focused on R&D investment and found that in most countries, R&D has

- number means that a 1% increase in R&D expenditure per labor leads to only 0.1% increase in productivity This number is acceptable because Griliches (1995) ng demonstrated in a cross-sectional study that the output elasticity of R&D capital was ep hi around 0.09-0.14 (cited in Wang and Tsai, 2003) Thus, physical capital and labor have more effects on productivity than R&D expenditure This can be explained that n w Vietnamese enterprises not care much about investing for R&D while labor is a lo cheap and easily-accessed input ad y th Even though the result that R&D expenditure has positive effect on productivity in ju yi this case, there are some points needed to be discussed Wang and Tsai (2003) said pl that the conclusion that R&D investment has a positively significant impact on ua al productivity in most studies may be overoptimistic due to the problems of 'file- n va drawer' and measurement of R&D capital As mentioned before, due to limitation of n the data, this study fails to measure R&D capital in a way other studies often It fu ll neglected the accumulation of R&D expenditure in the past, its lag, deflation and m oi obsolescence However, the regression result is a surprise to the author It may be nh at explained that because most R&D activities of Vietnamese enterprises are problem- z solving, not science-based; and most of R&D expenditure are for developing z ht vb technology, not for research (Figure 5.4) Such technology-developing activities have jm direct effects on technology and therefore on productivity more quickly than research k activities om l.c

There are two important tests in this model: multicollinearity and heteroscedasticity These tests are to make sure the statistic validity of the model It is unnecessary to test multicollinearity problem for the model because most of the correlation coefficients ng hi between regressors did not exceed 0.5, except some correlation coefficients relating to ep dummy variables (Table 5.3) Moreover, independent variables included in the model were statistically significant at 1% and R square of the model were lower than 0.8 w n (Table 5.4 and Appendix 2) Regarding heteroscedasticity, the model was handled to lo ad be free of it Detailed results of White Test are shown in the Appendix u yj th SUMMARY yi 5.3 pl ua al This chapter analyzed characteristics of firms in the sample and

though R&D capital was measured in a much si"mpler way than most u yj th related studies usually by using available R&D expenditure in the survey, the result is so surprised It is due to the

the industry sector, the Korean Government u yj th used a variety of methods and policies which were flexible to different periods and national development strategies In 1960s and 1970s, polices mainly focused on tax yi pl motivation and preferential treatment to R&D activities However, these policies' ua al results were below expected level because firms in the industry sector lacked of clear n demand for investment in R&D and they thought that it was easy to access prevailing va n technology from many sources In 1980s, there were other motivation methods such fu m ll as: decreasing tax rate applied for importing R&D equipment; spending for R&D and oi development of R&D human resources were considered as activities deducted from nh tax; or exempting fixed assets relating to R&D from taxes, and so on at z z ht vb Moreover, the Korean Government launched some indirect programs stimulating jm R&D activities such as International Standard Korean Products Program; or the k Government built a list of 21 products relating to 59 manufacturers in the industry gm sector to provide supports Besides tax motivation methods, the Government also had l.c financial supporting policies to encourage enterprises in investment for R&D om activities Small enterprises, which were unable to establish their own R&D centers, Lu were encouraged to cooperate with other firms Thanks to such solutions, the number an va ofR&D institutes and associations increased sharply, especially in 1980s- 1990s n use them as their key business assets In order to achieve the target, the program
