The Role of Technology, Investment and Ownership Structure in the Productivity Performance of the Manufacturing Sector in Vietnam

This paper explores the productivity performance of the manufacturing sector in Vietnam between 2001 and 2007. Total Factor Productivity indices are computed using an index number approach and the productivity performance of manufacturing sub-sectors is analysed. We find that productivity increases in almost all sectors and that for many sectors the dispersion in productivity is declining over time. However, for the most productive sectors the gap is widening suggesting that productivity is being driven by the most productive enterprises getting better, leaving the least productive behind. The empirical analysis reveals investment and technology usage as important determinants of enterprise productivity levels. Specifically, higher levels of productivity are found in foreign- and state-owned enterprises, driven almost entirely by higher levels of investment and technology usage. Our results provide a strong quantitative basis in support of ongoing government initiatives aimed at encouraging investment in technology and innovation. They also point to the clear need for such initiatives to be complemented by measures to provide a more balanced distribution of investment, such that a level playing field is created for the different types of enterprises.

Economic Instruments and the Pollution Impact of the 2006-2010 Vietnam Socio-Economic Development Plan

The current study derives optimal growth paths for pollution emission charges, in order to control future water pollution emissions in the Vietnamese manufacturing sector. The study builds on a prior study, which estimated the manufacturing sector pollution impact of the 2006- 2010 SEDP development plan for Vietnam (Jensen et al.; 2008). The current study demonstrates that effective implementation and moderate expansion of optimal emission charges, under certain conditions, could have been used, as part of the 2006-2010 SEDP development plan, to control pollution emissions at 2005 levels. Moreover, such a scenario would have been accompanied by a moderate expansion in fiscal revenues and a relatively minor economy-wide efficiency loss. The current study, therefore, suggests that effective implementation and gradual expansion of pollution emission charges should be incorporated into future SEDP development plans, in order to control pollution emissions as development progresses in Vietnam.Vietnam, manufacturing, CGE

Accounting for Vietnam’s Wealth: The Role of Natural Resources

This study estimates the capital or stock value of Vietnam’s natural resources. Natural resources are special economic goods because they are not produced. As a consequence, natural resources yield economic profits—rents—if properly managed. These rents can be an important source of development finance for poor countries (World Bank, 2006). The value of natural resources is estimated based on the net present value of income flows that can be generated from these resources (resource rents). Thus the capital value of natural resources is the based on the value an investor would pay for the resource based on its income flow potential. Together with measures of the value from Vietnam’s other important resources, human and produced capital, one could then assess whether Vietnam is on a sustainable development path by monitoring the value of its wealth overtime

Removal of Tetracycline from Aqueous Solution Using Nanocomposite Based on Polyanion-Modified Laterite Material

This work investigated the removal of antibiotic tetracycline (TC) from wastewater using nanocomposite material based on laterite modified with polyanion, polystyrene sulfonate (PSS). The effective factors influenced on the TC removal using nanocomposite PSS-modified laterite (NCPML) were optimized and found to be pH 4, solid-liquid ratio 5 mg/mL, and contact time 180 min. The highest removal of TC reached about 88% under the optimum adsorption conditions. The adsorption isotherm and kinetics of TC adsorption onto NCPML were in good agreement with the Langmuir and pseudo-second-order models, respectively. The characteristics of the NCPML material before and after TC adsorption were examined by zeta (ζ) potential measurements, Brunauer–Emmett–Teller (BET) method, and Fourier transform infrared spectroscopy (FT-IR). The TC adsorption onto NCPML was induced by electrostatic interaction, hydrogen bonding, and diffusion interaction. The TC removal from wastewater was approximately 94% while efficiency still reached 66% after five regenerations. Our research reveals that NCPML is a high-performance adsorbent for TC removal from wastewater
