Clemes, Baiding Hu and Xuedong Li The paper models the growth performance of the service sectors in China, Vietnam, Thailand, and Malaysia using data from 1995 to 2012 and examines the potential relationships between value-added in the service sector and value-added in the manufacturing sector, exports, imports, and government spending. The spillover effects between the service sectors and the manufacturing sectors in the selected Asian countries is also modelled. The data analysis is based a simultaneous equations model in order to investigate these effects. Finally, this paper presents its findings and policy implications.

Introduction The growth of global corporations and the development of modern technology have accelerated the rise of a service-dominated economy in many countries (Nissana, Galindob, & Méndezc, 2011). The service sector is identified as a crucial contributor to accelerating economic growth and furthering economic development in developed and developing countries (Gani & Clemes, 2013; Mizuno, 2005). The service sector’s ability to create employment is also highlighted in the literature (Buera & Kaboski, 2012). Gani and Clemes (2010) indicate that the expansion of the service sector has played an important role in the economic development of the Asian countries. In addition, the collaboration between the service sector and other sectors, particularly the manufacturing sector, has become more significant in the sustainable development of all sectors and the national economies of the Asian countries (Gani & Clemes, 2002). In general, the service sector has been deemed a residual tertiary sector after the manufacturing sector and the agricultural sector in many developing countries (Gani & Clemes, 2013). However, the importance of the service sector is fully recognized only when the basic needs and demands of the primary and secondary sectors are satisfied (Gani & Clemes, 2010; Park & Chan, 1989). Moreover, Gershuny and Miles (1983) have categorized service activities into two major groups: market and nonmarket. Market services include producer services, distribution services, personal service, and communication. Non-market services include social services.

Jansson (2006) defines the service sector based on production and distribution as the tertiary stage in a description of an economy. Table 1 shows the division of the economy into three stages. Table 1: The Service Sector as the “Tertiary Stage” Mining, agriculture, forestry, fishing Manufacturing and building industry Wholesaling and Transport retailing hotels and and communication restaurants 1.1 Banking, insurance and other business services Health, education, child and elder care and other personal services Primary production stage Secondary production stage Tertiary production stage Contribution of this Current Study In recent years, the service sector has been identified as playing an ever-growing role in the development of the many countries’ economies (Buera & Kaboski, 2012). However, there have been only a few studies with a general focus on the service sector in the Asian region, mainly Gani and Clemes (2002, 2010), Singh (2010), Anwar and Sam (2008) and Kanungo (2005). In particular, published economic research on the service sectors in China, Malaysia, Thailand and Vietnam is sparse. Therefore, this study empirically investigates the potential factors that contribute to the expansion of the service sectors in the selected four countries. The expansion of the service sector is also compared between China and the three other countries. Moreover, the relationship between the service sectors and the manufacturing sector in all four countries is also examined. The purpose of this research is to firstly compare the growth performance of the service sectors in China, Vietnam, Thailand, and Malaysia, and secondly to examine the potential relationships between value-added in the service sector and valueadded in the manufacturing sector, exports, imports and government spending. This research uses a simultaneous equations model to estimate the spillover effects between the service sectors and the manufacturing sectors in the selected Asian countries. The paper is organized as follows: Section 2 describes the sectorial composition of China, Malaysia, Thailand and Vietnam. Section 3 presents the estimation framework. Section 4 includes the data analysis and discussion, the estimation procedure and presents the empirical results. The final section presents the conclusion and implications. 2. Literature Review Figures 1-4 show the changes of value-added in three major sectors (manufacturing, agricultural and services) in the gross domestic product (GDP) and the growth of the Proceedings of 29th International Business Research Conference 24 - 25 November 2014, Novotel Hotel Sydney Central, Sydney, Australia, ISBN: 978-1-922069-64-1 service sector in China, Malaysia, Thailand and Vietnam from 1995 to 2012. However, as shown in Figures 1-4, the data for value-added in the service sector, growth of the service sector, value-added in the manufacturing sector, and valueadded in the agricultural sector in Vietnam and Thailand in 2004 and 2012 are missing from the Asian Development Bank Data Base, respectively. Figure 1 shows that Thailand’s service sector is the main contributor to GDP. Moreover, value-added in the service sector to GDP in Thailand has been more than 50% during the last decade. This is higher than the value-added in the service sectors in China, Malaysia and Vietnam.

However, China has a relatively higher growth rate in its service sector than in those of the other three countries. In particular, China’s service sector growth rate was at 16% in Proceedings of 29th International Business Research Conference 24 - 25 November 2014, Novotel Hotel Sydney Central, Sydney, Australia, ISBN: 978-1-922069-64-1 2007, which was much higher than the growth rate of the service sectors in the other three countries. In terms of the manufacturing sector, Figure 3 shows that China’s GDP has relied heavily on the growth of its manufacturing sector. The share of the manufacturing sector to China’s GDP is close to 50%, which is higher than Malaysia, Thailand and Vietnam, particularly during 1995 to 1999 and 2007 to 2012.

Meanwhile, the growth rate of Malaysia and Thailand’s agricultural sectors has only changed slightly between 2005 and 2012. The value-added in the agricultural sector has declined in the four selected countries. However, a considerable amount of research is still conducted in the agriculture sector throughout the world, even though the agricultural sector is not dominant in many countries (Gani & Clemes, 2010) .

For example, China’s “reform and opening-up” policy in 1978 has developed and promoted the manufacturing sector, which has attracted great attention from academia (Liu & Li, 2012; Wong, 2013). 3. The Estimation Framework The estimation framework in this study was formulated after two key issues were addressed. First, identifying the potential contributors to the growth of the service sectors in China, Malaysia, Thailand and Vietnam. Second, overviewing the possible spillover effects from the service sector to the manufacturing sector and vice versa in the selected four countries. The estimation framework in this study is based on the framework used in Gani and Clemes’ (2002, 2010) studies. The empirical methods used in the authors’ studies analyse the two issues in the selected five ASEAN countries (Indonesia, Malaysia, Philippines, Singapore and Thailand) and the four Pacific Island countries (Fjiji, Papua New Guinea, Tonga and Vanuatu). In Gani and Clemes’ (2002, 2010) studies , the service sector (ser) is hypothesised to be influenced by the growth of real output (gdp), the growth of the manufacturing sector (mangth), the growth of exports (x) and imports (im), and government spending (gov). In addition, estimation of the spillover effects from the service sector to the manufacturing sector and vice versa is formulated as the value-added in the manufacturing sector (man) being influenced by the lagged value-added in the manufacturing sector (mant-1), the growth of real output (gdp), value-added in the service sector (sva), growth of exports (x) and imports (im) and government spending (gov). t and i represent time and each country, respectively. The structural equations are as follows: (1) (2) serit = manit = α0 + α1gdpit + α2mangthit + α3xit + α4imit + α5govit +µ1t β0 + β1manit-1 + β2gdpit+β3svait +β4xit+β5govit + µ2t However, this current study adjusts some variables in each equation in order to improve the appropriateness of the model for the selected four countries. Moreover, this study adopts simultaneous equations model to estimate the spillover effects of the service sector to the manufacturing sector and vice versa. Hill, Griffiths and Lim (2011) stress that simultaneous models include two or more dependent variables and consist of set equations. The two-way influence between the service sector and the manufacturing sector can be estimated at the same time by using a simultaneous equation model. Hence, the equations are: (1) svait = (2) mangthit = serit α0 + α1manit + α2xit + α3imit + α4govit +µ1t β0 + β1mangthit-1+β2serit+β3gdpit + β4govit + µ3it = δ0 + δ1serit-1 + δ2mangthit +δ3xit + δ4imit+ δ5govit + µ4it In equation (1), the growth in value-added in the manufacturing sector is included to test its influence on the growth in value-added in the service sector. Gani and Clemes (2002) note that the improvement in efficiency in the manufacturing sector may promote expansion of the service sector. In addition, the variables exports and imports are included as they are the connection between the domestic economy and Proceedings of 29th International Business Research Conference 24 - 25 November 2014, Novotel Hotel Sydney Central, Sydney, Australia, ISBN: 978-1-922069-64-1 the global economy (Gani & Clemes, 2010). Exporting and importing introduce and spread the latest technological developments, which are considered to be the core of the service sector development (Nissana et al., 2011). Government spending, gov, has a beneficial influence on the manufacturing sector’s growth and the service sector’s growth, which is mainly reflected in public infrastructure development (Temple, 1999). Further, this current study examines the relationship between valueadded in the service sector and the potential impacting variables in China, and by combining the data for the other three countries. Malaysia, Thailand and Vietnam have economies that are similar in size and structure. However, China has a relatively larger economy that is much more complex in structure. The simultaneous equation model include endogenous and exogenous variables in two equations. These equations are applied to test the spillover effects from the service sector to the manufacturing sector and vice versa. In terms of the endogenous variable, service sector growth is predicted to be determined by the growth in the manufacturing sector. In terms of the exogenous variable, the service sector combines with the variables of GDP and government spending in order to examine its impact on the manufacturing sector. In addition, the variable mangth is also both an endogenous and exogenous variable. There is a connection assumed between the growth of the service sector and the growth of the manufacturing sector as the manufacturing sector and the service sector can jointly improve the diversity of products, and this combination strengthens their international competitiveness (Yoon & Choi, 2002). The growth of GDP, gdp, is expected to have a favourable influence on the growth of the manufacturing sector. The remaining variables: the growth of exports (x) and imports (im), and government spending (gov), have the same justification for being selected as explained in Equation 1. 4. Data, Estimation Procedure and Empirical Results The data period for the selected Asian countries (China, Malaysia, Thailand and Vietnam) extends from 1995 to 2012. The Asian Development Bank is the data source for all variables in the selected countries: service sector growth, value-added in the service sector, manufacturing sector growth, value-added in the manufacturing sector, growth of exports and imports, government expenditure, gross domestic product (GDP). The collected data is analysed using Eviews8 software. The potential influence of the variables on the growth of the service sector is estimated using panel estimation, in Malaysia, Thailand and Vietnam. Moreover, the potential factors of value-added in the manufacturing sector, growth of exports and imports, and government spending in the expansion of each country’s service sector are identified using multiple regression analysis. Further, a simultaneous equations model is applied to test the spillover effects from the service sector to the manufacturing sector and vice versa. The results of the regression analysis relating to Research Questions 1 and 2 are presented in Tables 2-4. The goodness of the fit is measured by the adjusted R 2 which is considered to be satisfactory (Nieuwenhuis, 2009).

The regression results in Table 2 confirm that the variables of value-added in the manufacturing sector and growth of exports have a positive influence on the value-added in the service sectors in Malaysia, Thailand and Vietnam. The growth of imports and government spending negatively influence value-added in the service sector. Additionally, value-added in the manufacturing sector and growth of exports are statistically significant at the 1 per cent level and the 5 per cent level, respectively. The positive effect of the manufacturing sector on the service sector indicates that the manufacturing sector has an important influence on the performance of service sector development in the three countries. In addition, the results for fixed effects for all four countries indicate that value-added in the service sector in Thailand is higher than in China. Moreover, Malaysia has the lowest value-added in the service sector among the four countries. Table 3 shows that the value-added in the manufacturing sector, growth of exports and imports, and government spending are statistically significant only for China. The beta coefficients suggest that an increase in exports and government spending will positively affect value-added in China’s service sector. However, value-added in the manufacturing sector and imports have a negative influence on value-added in the service sector. Table 2 and Table 3 present two converse effects of value-added in the manufacturing sector on the value-added in the service sector between the three selected countries and China.

Table 4 shows the results of the spillover effects from the service sector on the manufacturing sector and vice versa for all four countries. The regression analysis shows that the service sector and government spending have a negative influence on the manufacturing sector for all countries and the lagged manufacturing sector and the GDP growth rate are positive, influencing variables. In terms of statistical significance, the service sector and GDP are statistically significant at the 1 per cent level, and government spending is statistically significant at the 5 per cent level for all four countries. In addition, the regression results from the second equation suggest that the lagged service sector, the manufacturing sector, growth of imports and government spending positively influence the service sector in all four countries. The growth of exports is found to negatively influence the service sector growth four all four countries. However, in terms of statistical significance, only the lagged service sector is statistically significant at the 1 per cent level. The results illustrate that service sector growth does not contribute to growth in the manufacturing sector and growth in the manufacturing sector is also insignificant to growth in the service sector for all four countries. Therefore, positive spillover effects from the service sector to the manufacturing sector and vice versa are not supported by the results of the statistical analysis. Further, the fixed effects results indicate that the growth of the manufacturing sector in China is statistically significant and positive. The manufacturing sector has a higher level of significance in China than in Malaysia, Thailand and Vietnam. Additionally, the results also show that the growth of the service sector in China and Vietnam is positive.

Summary and Conclusion The influential factors involved in the expansion of the service sectors in China, Malaysia, Thailand and Vietnam during the period from 1995 to 2012 have been examined in this study. In addition, the spillover effects from the service sectors to the manufacturing sectors and vice versa are tested using a simultaneous equation model. The key findings of this paper on the expansion of the service sector and the spillover effects between the service sectors and manufacturing sectors will add to the extant economic literature on these effects for the four countries. The empirical results confirm that for Malaysia, Thailand and Vietnam, there is a strong, positive influence of value-added in the manufacturing sector. There is also a strong, positive influence of growth of exports on value-added in the service sector for the three countries. However, these relationships are not consistent for China, as the effects are significant but negative for the growth of value-added in the manufacturing sector. The findings for Malaysia, Thailand and Vietnam are consistent with the results of Gani and Clemes’ (2002) study on the ASEAN countries (Indonesia, Malaysia, Philippines, Singapore and Thailand). The empirical results also confirm that the growth of exports and government spending significantly and positively affect the value-added in China’s service sector. The growth of exports is also positive and significant for Malaysia, Thailand and Vietnam. However, government spending is negative and insignificant for the three countries. The result for the effect of government spending on China’s service sector is supported by Gani & Clemes’ (2010) results for the Pacific Island Countries. In addition, the empirical results on the spillover effects from the service sector to the manufacturing sector reveal a negative and statistically significant effect of the service sector on the manufacturing sector for all four countries. However, for the four countries, there is a positive and statistically significant effect of the manufacturing sector on the service sector. In terms of the political implications associated with the results, China, Malaysia, Thailand and Vietnam would benefit from their respective governments providing greater support for the development of their service sectors. For example, China provides more governmental financial support for its service sector when compared to the contribution provided by the other three countries. China’s support facilitates the growth in its service sector as illustrated by our results. Increased government support for the service sectors in in Malaysia, Thailand and Vietnam should also encourage growth in their respective service sectors. In particular, an increase in the export of services eventuating from this type of policy initiative would be beneficial for these three countries, as their governments are currently encouraging the exports of goods and services. China’s economy may benefit if the governement eases the negative influence of the manufacturing sector on the service sector. China’s manufacturing sector has been particularly buoyant during the last decade. However, China’s manufacturing sector is under increasing competition from other nations such as Indonesia and Vietnam. A decrease in the output of the manufacturing sector has occurred in countries such as Japan, and more recently in South Korea. China’s government may want to rationalise the allocation of its resources to facilitate a more equitable development Proceedings of 29th International Business Research Conference 24 - 25 November 2014, Novotel Hotel Sydney Central, Sydney, Australia, ISBN: 978-1-922069-64-1 of the service sector and the manufacturing sector in order to avoid repeating the scenario. China also may not fully recognize the contribution of its service sector to the manufacture of physical goods as it may not measure the contribution accurately on a national scale. Further, all four countries need to investigate the existing inter-connections between growth in their service sectors and growth in their manufacturing sectors. This type of comparison will provide a valuable insight into the drivers of economic growth and should enhance the competitiveness of both sectors in the global market for all four countries. 6. Limitations and Avenues for Future Research The dependent and predictor variable used in this research are based on Gani and Clemes’ (2002, 2010) studies. Thus, other potential factors such as foreign direct investment may be considered by future researchers. In addition, this research uses cross-country data to estimate the equations. Since the research assumes that the selected four countries and their service sectors have similar production functions, the estimating equations and the production assumptions may not be suitable the economic conditions for all four countries. Therefore, a country-specific study may provide improved individual results, which would reveal the distinguishing characteristics of each country’s economy, and in particular, the distinguishing characteristics of each country’s service sector.
