The significance of high-quality development and green total factor productivity has attracted widespread attention and research, while few studies on green total factor productivity that considers the use of water resources have been conducted in the context of water shortages and water stress. In this study, the green total factor productivity of water use from 2005 to 2015 in mainland China is evaluated based on the global Malmquist-Luenberger productivity index. Results show that: (1) China's green total factor productivity of water use has been improving since 2005 with an annual global Malmquist-Luenberger productivity index of 1.0104. (2) At the regional level, the eastern zone in mainland China owns the highest green total factor productivity of water use, while that in the intermediate zone ranks last. (3) The green total factor productivity of water use in the southern region (1.0113) significantly higher than that in the northern region (1.0095), and also higher than the national average level in the same period. BPC index has been the most important incluencing factor of green total factor productivity of water use at both national level and regional level since 2011.

Vietnam is conducting an export-led growth model and labour-intensive industries contributing majorly to the total export value. In the context of Industry 4.0, the labour-based industries are significantly affected; hence, enhancing productivity is the key measure to maintain these industries. The garment industry contributes significantly to the total export value of Vietnam. Based on meta-frontier framework, the approach of data envelopment analysis is used to measure technical efficiency of Vietnamese garment firms and the global Malmquist TFP index is utilised to identify productivity change and its components including efficiency, technology and technical gaps between different groups of firms. The data of Vietnamese garment firms from 2013 to 2018 collected from the Vietnam General Statistic Office is used in this study. The results show that: (i) The total factor productivity of Vietnamese garment firms growth, technical progress is the main contributor; (ii) The private garment sector is the leading group; (iii) There is a large technological gap among Vietnamese garment sectors. The private and FDI garment firms have experienced a growth in all components of total factor productivity change. Meanwhile, technological progress change is the main reason to constrain the productivity growth of state-owned garment firms.

본 고는 Malmquist 생산성 지수를 이용하여 글로벌 금융위기 이전인 2001-2008년, 그 이후인 2008-2015년 두 기간 동안 조선 산업의 생산성변화를 기술효율성변화, 순효율성변화, 규모효율성변화, 기술변화로 구분하여 측정함과 동시에 두 기간 동안 생산성 변화를 비교하였다. 전반기(2001-2008년)에는 2.8%의 생산성 향상되었으며, 이는 기술효율성 보다는 기술진보에 기인된 것으로 나타났다. 후반기(2008-2015)에는 -3.4%의 생산성 하락으로 나타났다. 이는 글로벌 금융위기이후 세계경제의 침체로 인한 선박수주 물량의 감소, 중국 조선 산업의 부상 등으로 인해 기술효율성 저하, 기술퇴보 등에 기인된 것으로 나타났다. 두 기간 중 전반기 가 후반기보다 생산성이 높게 나타났다. 특히 두 기간 간에 이러한 차이는 기술변화에 의해 기인된 것으로, 즉, 기술 퇴보는 생산성 감소로 나타났으며, 통계적 검증을 통해서도 이를 입증할 수 있었다. 본 연구 결과에 의한 정책적 시사점으로는 정부 그리고 각 DMU들은 향후 생산성 증대를 위해, 글로벌 조선 산업의 환경변화에 대응하는 신기술개발 그리고 비효율적 요인을 제거하는 전략이 필요하다는 점을 제시하고 있다.

Purpose - The purpose of this paper is to analyze the net effect of the green total factor productivity (GTFP) of China's manufacturing industry from the China-Korea Free Trade Area (China-Korea FTA) quantitatively. Design/methodology - Firstly, the Global Malmquist-Luenberger (GML) index based on the SBM directional distance function is used to measure the GTFP of China's manufacturing and analyze the driving force for its growth. Secondly, the regression discontinuity quantitative analysis is used to determine the impact of the China-Korea FTA on China's manufacturing GTFP. Findings - Our main findings can be summarized as follows: the China-Korea FTA has promoted the GTFP of China's manufacturing with an effect evaluation mainly resulting from green technology progress. And there is industry heterogeneity in the policy effect on the manufacturing GTFP due to the China-Korea FTA. Namely, policy promotion from the China-Korea FTA is more effective on the GTFP of equipment manufacturing than it is on those of other industries. Originality/value - First, an evaluation and analysis of the GTFP development of China's manufacturing that employs GML index based on SBM directional distance function. Second, a quantitative estimate of China-Korea FTA's net effect on China's manufacturing industrial GTFP that uses regression discontinuity analysis, which is considered to be the closest method to natural experiments and superior to other causal inference methods. Third, an in-depth discussion of the practical steps that China's manufacturing can take to improve GTFP development and integrate China-Korea FTA construction into economic development.
