Green Economy Development in Vietnam and the Involvement of Enterprises

Vietnam has become increasingly integrated into the global economy since its accession to the WTO in 2007, which is not only beneficial, but also detrimental. Membership was almost immediately followed by the 2008 global financial crisis which, along with Europe’s escalating public debt, dramatically slowed Vietnam’s, at that time, rapidly developing economy. To mitigate the persisting effects of that economic shock and facilitate growth sufficient to the needs of its citizens, Vietnam is obligated to reevaluate the sustainability of its “brown economy” and develop strategies toward the adoption of a “green economy” growth model. Vietnam is fortunately located in a region that has been experiencing dramatic economic development and with its neighboring countries, many advantageous social and legal conditions for the development of a green economy. Yet, Vietnam’s economy persists in being driven by a brown growth model which is characterized by reliance on raw materials production, the consumption of unsustainable quantities of fossil fuels and natural resources and burgeoning environmental pollution. This paper provides a nation-level analysis of green technology development in Vietnam by using the data from the National Office of Intellectual Property to analyze the extent to which green technology constitutes technology use in Vietnam. Vietnamese enterprises were interviewed to gain insight and data regarding the development and renovation of green technology. Given this situation, an assumption is made that initial growth in greening the economy is primarily driven by enterprises. Greening economy can start from technology renovation and it was hypothesized that such renovation would have been due to both knowledge-based labor and outside support. It was also hypothesized that green economy can be pushed under the outside pressure on Vietnamese enterprises. This paper was designed to test these hypotheses.


Introduction
Green economic development has been a global trend for sustainable growth in developing countries.Vietnam is no exception.The "Agenda 21" action plan on sustainable development identified that the country's official task was to change its growth model and restructure the economy towards sustainable development.Vietnam is in the most dynamic economic region in the world and has favorable conditions for greening the economy.However, it is also admitted that a green economy has not developed in Vietnam.Vietnam's economy persists in being driven by a brown growth model which is characterized by reliance on raw materials production, the consumption of unsustainable quantities of fossil fuels and natural resources and burgeoning environmental pollution.In fact, the dominant forces in the economy are unsustainable energy-intensive highly polluting raw materials processing industries, the antithesis of green technology.
A large body of academic research studies green economic concepts from various perspectives, the needs and the requirements for green economic development in both developed and developing countries and the common view is that the green economy is one in which the contribution of enterprises plays a dominant role.Many empirical studies in the literature to date examine the strategies adopted by a variety of businesses, which have helped to fuel green development in economic sectors such as energy, technology, agriculture, etc. and in many countries, including Vietnam.
Vietnam's economy is in the process of developing and opening up to world markets.Clearly, new strategies are required.Given the importance of the greening transition in the process, there have been a lot of studies focusing on the policy framework for the green economy development in Vietnam [1]- [4].There are a few researches at firm-based level on the involvement of enterprises on green economic development in Vietnam.Our study attempts to fill in this gap in the literature by the assumption that initial growth in greening the economy is primarily driven by enterprises.Greening economy can start from technology renovation and it was hypothesized that such renovation would have been due to both knowledge-based labor and outside support.It was also hypothesized that green economy can be pushed under the outside pressure on Vietnamese enterprises.This paper was designed to test these hypotheses and aimed at addressing obstacles to the contribution of enterprises to the green economy development in Vietnam.

Green Economy
The topic of the green economy has been debated since the 1970s, and especially since October 2008 when UNEP together with the developed economies implemented the idea of the green economy.It is possible to broadly categorize research reports about the green economy into two groups.The first group specializes in basic concepts, principles and views of green economic development such as Holger Rogall (2011), Nachhaltige Ökonomie-Ökonomische Theorie und Praxis einer nachhaltigen Entwicklung; Earthsummit 2012, Principles for the green economy: a collection of principles for the green economy in the context of sustainable development and poverty eradication; OECD (2011) Towards green growth: A summary for policy makers, Paris; UNEP (2011), Towards a green economy: Pathways to sustainable development and poverty eradication, Nairobi; UN (2012), Working towards a balanced and inclusive green economy: A United Nations System-wide perspective [5]- [9].
The second group analyzes specific situations and development strategies in some countries and regions such as UNESCO (2011), from green economies to green societies, Paris; UNEP (2010), Green economy-Developing countries success stories, Nairobi; Stern.N. (2007), The Economics of Ecosystems and Biodiversity: Mainstreaming the economics of nature: A Synthesis of the Approach, Conclusions and Recommendations, TEEB; Robins, N. et al. (2010), Green austerity hits the UK, London: HSBC Global Research, Climate Change [10]- [13].Reports in the final group analyze how to develop a green economy in specific areas such as OECD (2011), A green growth strategy for food and agriculture-preliminary report, Paris; UNEP (2010), Green economy: Driving the green economy through public finance and fiscal policy reform, Nairobi; J. Stephenson and S. Upton (2010), Strategies for green growth: Framing and issues, OECD [14]- [16].The publications mentioned above share the view that green economy is necessary for sustainable development and is the most viable economic model for many developing countries despite the high cost of implementation of the necessary strategies.From such publications, 14 models of the green economic development can be sketched.Although each country has its own models, the common feature that they share is investment in clean technology, clean production, efficient use of natural resource and green energy.
Researches in Vietnam [17] [18] come to the three vital elements of green economy in Vietnam, which are clean economy (i.e.high intellectual property contained), environment-friendly economy and green development.Bui Quang Tuan [17] has pointed out ten principles of green economy, which are 1) sustainability, 2) existence, 3) healthiness, 4) humanity, 5) fairness, 6) protection, 7) effectiveness, 8) accountability, 9) sufficiency, 10) responsible creativeness.Green economy development in Vietnam is suggested to be done in all three areas including economy, society and environment [19].This view is repeated in the National Strategy of green growth approved on 25 th September 2012.Do Huu Hao [20] stressed the importance of green industry as basis of green economy development in the country.A strong financial status is needed for the development meanwhile national reserves in Vietnam is said to be insufficient, which subtantially affects the result.

Hypotheses
Investment in clean technology, clean production can come from state and/or from enterprises.97.5 % of enterprises in Vietnam are small and medium sized [21].They have played an important role in the national economy.However, as noted by Tran Tien Cuong et al. [22], enterprises' technology is basically at the first stage of developing technology which is adopting technology.It is a waste if Vietnam relies the development of green economy on the State and ignores enterprises.Enterprises' renovation of existing technologies into those which are clean and/or renewal are believed to help pushing up the transformation process from brown economy to green one in the country.There are some prominent examples of government's success in directing firms and markets to green economy in reality, especially in histories of many recently emerged economies.During the periods of 1950s and 1960s, both Japanese and South Korean governments decide to lead their technology industries change through importing from other countries.This choice in the 1970s happens while these countries were in the mist of encouraging policies for energy-efficient innovation.Then, shortly afterwards, Japan became one of the leading economies in terms of research and development (R&D) investment in these industries.
Many studies have proved that financial factors like cash flow, research workers' salaries, etc. much influence on the R&D expenditures, which is key to renovation [23]- [25].Finance is always a serious problem for enterprises in Vietnam and is used as a good excuse for them not to invest in renovation [26] and there are many studies both at macro-level and micro-level on how to deal with the situation.Therefore, this paper looks at nonfinancial factors.The following hypotheses are proposed:

Hypothesis 1: Renovation motivation in Vietnamese enterprises is positively associated with non-financial factors including knowledge-based labor force and outside support.
There has been a strong trend of thought running through some studies which consider scientific personnel among dominant motivations for companies to focus on R&D [27] [28].Education and vocational training system in Vietnam have not been efficient with the university curricula being very theoretical.Therefore, without knowledge-based labor force, enterprises with sufficient fund for R&D cannot be motivated with renovation [22] [29].Besides, for a long time, the linkage among research institutions, enterprises has been so weak, resulting in the fact that enterprises have been isolated in technology renovation [30] and out dated with the recent trend of green renovation.Therefore, it is expected that supports from the Government, research institutions or business partners shall push the Vietnamese enterprises to renovate technology, especially to the green technology [31].
Hypothesis 2: Green renovation in Vietnamese enterprises is positively associated with outside pressure.
Luo & Bhattacharya [32] has proven that the organization's behavior toward corporate social responsibility including green production stems from various outside pressure, especially from the customers' responsiveness.While there is a high awareness for green growth in Vietnam, micro development in green areas is rather at the beginning stage [33].Therefore, the study assumes that Vietnamese enterprises' attitude on green renovation shall change in accordance with outside pressures.We aim at testing if the change is positive and what outside pressures are for Vietnamese enterprises.

Research Context
The research is tested in the context of Vietnam, an economy which is in the transitional period from brown into green.
Green technologies are primarily used in only six areas: construction, transportation, agriculture, industry, energy and waste treatment.41% of the green technologies used in waste treatment are for filtration, clean water supply, and waste collection from production, medical facilities and residential use.Most of the green patents in energy are devoted to the production of electricity using solar and wind energy.R&D activities in construction, transportation and agriculture are not fully invested despite their important role in the process of greening the economy.
With 31 million motorbikes and more than 1.6 million automobiles in Vietnam, transportation is by far the greatest polluter of the environment.Only 4% of the green patents were granted in the transportation industry, and those were specifically for intelligent transportation systems, infrastructure quality and new more fuel efficient engines.
Among green technologies, some patents have been granted.Patents granted for green technologies were compared with ordinary technologies in Figure 1.
Green patents account for 2.18% of total patents granted annually, which is said to be extremely inadequate (see Figure 2).It is evident that there is little incentive to develop green patents.
Green patents in Vietnam are held by 6 groups of patent holders: multi-national organizations (including enterprises, investment funds, NGO), local enterprises, universities, research institutes, Vietnamese and foreigners (see Figure 3).Most green patents are in the hands of multi-national organizations.
It has been noted that green patent exploitation depends on research, development and patent licensing activities from multi-national organizations.Such organizations when implementing technology transfer to Vietnam, assign or license a few green patents only, accounting for 1.8% of the total [34].There are no official statistics for environmentally friendly patent exploitation by individual holders.Universities and research institutes should be expected to actively participate in the process of new and green technologies renovation and application.However, their research and development mainly meet the demands of the State and depend on State financing.They hold only 8% of the green patents as shown in Figure 3. Vietnam Technological Science Institute, Vietnam Social Science Institute, Hanoi National Universities and HCM National Universities are the four larg-  est and most productive universities and research institutes contributing to from 40% to 50% of national research [35].It is admitted that there is a gap between patent development and effective patent exploitation from the said organizations.

Data and Methodologies
We used data obtained from the survey conducted in 2014 in which we interviewed 450 enterprises in Hanoi, Ho Chi Minh City, Da Nang and Quang Ninh.Hanoi and Ho Chi Minh City are the two biggest centers of economy, education and technology in the North and the South of the country so we assume that enterprises there shall be leaders in green technology renovation.Da Nang and Quang Ninh are situated in the centre and northern centre of Vietnam and are considered to be dynamic in technological areas.Questionnaires were prepared and sent to the said enterprises by postmails and emails.
The number of enterprises in interview was 26.4% in Ho Chi Minh City, 62.9% in Hanoi and 10.6% in Quang Ninh and 10.6% in Da Nang.75.3% of enterprises interviewed situate in urban area; 20.7% of enterprises interviewed are in industrial zone; 2.7% are in hi-tech parks and only 1.3% are in processing zone.
To ensure the accuracy of the information collected, we arranged interviews with management boards or heads of R&D departments of 20 outstanding enterprises in the fields (see the Appendix for the list of these entrepreneurs).
We arranged meetings with legal scholars and economists in the Central Institute of Economic Management to exchange information and private assessments regarding the restructuring of Vietnam's economy from brown to green.
Besides, the paper used data obtained from the National Office of Intellectual Property to have an overview of green technologies in Vietnam and work out the number of green patents out of the total granted in Vietnam up to 2013 in order to quantize the process of greening the economy in Vietnam.First, bivariate relationships among variables were explored via correlation analysis.Then, multiple regression analyses were performed to test proposed hypotheses.The Statistical Package for the Social Sciences (SPSS) was used to support the analyses.

Hypothesis Testing: Motivation of Renovating Technology in Enterprises
Renovation motivation in Vietnamese enterprises is positively associated with knowledge-based labor (Table 1).
We use logistic model to valuate factors affecting on the enterprises' decision of technology renovation toward clean and green.
Knowledge-based labor was thought to be important for the enterprises to push the process.We assume: Regression of logistic model is used to evaluate the influence of knowledge-based labor on renovation.
As can be seen from the regression, the variable of labor does not have significant impact on the renovation in an enterprise.Same result has shown when ld e is replaced by ld_dh, ld_cd.

Renovation Motivation Is Positively Associated with Outside Support
Regression of function (2) provides X i value 1 provided support from outsiders and 0 with no such support.Outsiders can be authorities, research institutions, business partners, etc. Regression results from Table 2 have shown that only X 3 variable which is the support from outside has effect on renovation motivation.
Table 3 proves that business partners are vital sources to motivate enterprises to renovate their existing technology in general and green technology in particular.The role of research institutes can be seen modest.The support from authorities is weak as well.

New Determinant Discovered
Logistic regression of other determinants is also done as below:   Table 4 also reveals a determinant which positively associated with renovation motivation in Vietnamese enterprises, which is pressure from existing environment relating certificates.As can be seen, enterprises holding environment relating certificates have the ratio of 2.4 of technology renovation in comparison with the others.

Hypothesis Testing: Green Renovation in Vietnamese Enterprises Is Positively Associated with Outside Pressure
The survey includes a question on the determinants of the green development for enterprises with the Likert scale from zero-no importance to 5-extremely importance.The result can be seen in the Table 5.
Table 5 shows that customers' requirements and authorities' requirements are the two outstanding determinants of the green development for enterprises (the mean is more than 3).This result is fit with the existing surveys.Only 28% out of the 9012 production enterprises nationwide are aware of green production, 11% thereof have applied green production to reduce energy consumption per product unit, and only 18% have employed competent staff for green production [29].Moreover, some enterprises hold the opinion that investment in technology generally or in green technologies in particular can only be managed by large enterprises.
Customers in 91 enterprises in our survey have required environment relating certificates but only 39 enterprises can meet such demand.
56% of the enterprises admitted that green development has been urgent need for them to improve their competitiveness (the Likert scale is 4 out of 5).The outside pressure for green development on the enterprises has been seen increasing.Around 10.2% of the enterprises in the sample have certificates relating to green development like certificates of environment, etc meanwhile 30.56% enterprises have faced with the requirement of such certificates from their customers and 29.4% enterprises have been asked to show such certificates in order to access foreign markets.Those numbers have shown that Vietnamese enterprises have lost many opportunities to access new markets, new customers.

Discussion and Implications of the Research
This study explores the relationships among renovation motivation in Vietnamese enterprises, knowledge-based labor and outside support.Inconsistent with the existing literature where knowledge-based labor was found to be dominant motivation for companies' renovation, the study shows that such labor force does not have significant impact on the renovation in an enterprise in Vietnam.
It is proven here that there is a strong linkage between renovation and outside supports (authorities, business partners, research institutes).Also, customers' requirements and authorities' regulations are two outstanding determinants to push the renovation toward greening process.Therefore, it is recommended for the government to develop these links and to erase obstacles which weaken such links.The obstacles can be unavailable subsidies for clean electricity, discouraging investment in wind and solar energy [36].
It is found in this study that pressure from existing environment-relating certificates is positively associated with renovation motivation in Vietnamese enterprises.The government should take advantage of such pressure to encourage enterprises to invest resources in the development of green patents and/or to the exploitation thereof in the shortest time as implemented in Japan and the United States [37] [38].
This study has two main limitations.First, it relies on cross-sectional survey; therefore, causal relationships among variables cannot be confirmed.Second, measures of determinants are still based on subjective assessment of managers in the enterprises.Future research could address these weaknesses by including objective measures of determinants and conducting longitudinal studies.
Despite all the limitations, results of this study still advance our knowledge of the relation between the green economy development and enterprises' involvement.The study has provided some important implications for enterprises' managers and for policy makers.
