“…Oriented DEA ignores aspects of inputs or outputs and also leads to inaccurate results. To overcome these problems, Fare et al [29] and Fukuyama and Weber [30] developed the slacks-based measure directional distance function (SBMDDF) which is based on the SBM model dealing with the undesirable outputs of Tone [31].…”

Foreign Direct Investment (FDI) not only affects the economic growth but also affects the environmental protection of the host country. With China's background of pursuing green growth, we need to consider the performance of FDI from the economic and environmental benefit aspects. On this basis, using slacks-based measure directional distance function (SBMDDF) to build up green growth efficiency, economic efficiency and environmental efficiency indexes, empirical research on FDI in 104 Chinese cities from 2004 to 2011 has shown that: (1) Different cities have differences in their green growth efficiency. Shenzhen city is always efficient in green economic growth. (2) Overall, FDI is positive on Chinese cities' green growth. (3) When the green growth efficiency is broken down into economic efficiency and environmental efficiency, FDI promotes China's economic green growth through both environmental benefits and economic benefits. (4) The effect of FDI differs in different sectors. FDI in the emission-intensive sector promotes green efficiency mainly through the improvement of economic efficiency. FDI in the non-emission-intensive sector promotes economic efficiency, environmental efficiency and green efficiency.

“…The basic DDF function generalizes radial measures of technical efficiency since it allows for radial expansion of outputs and contraction of inputs as well as a non-radial expansion of outputs and contraction of inputs [24]. It does not provide technical efficiency information for specific inputs or outputs as it adjusts all inputs and outputs by the same proportion to the efficient targets.…”

Abstract:The medical care system in China has experienced significant changes during three decades of reform, and thus result in a need to investigate the effects of medical reform. This paper investigates the technical efficiency of Chinese hospitals in 31 provinces during the period from 2002 to 2013 by proposing a new global generalized directional distance function (GGDDF) approach taking account of undesirable output, i.e., mortality. Results show that despite the technical efficiency had being improved with time trend, most Chinese provinces are not performing well on hospitals' technical efficiency and leave a large potential to improve. Some provinces display better performance compared to other provinces of China. We further investigate the factors that affect the technical efficiency of Chinese hospitals with Tobit models. It concludes that the medical insurance reforms have improved the performance of Chinese hospitals, while public subsidies have decreased it. The provinces with higher GDP per capital and population density, the performance of their hospitals is better. The related policy implications for Northeast Asia are derived, including encouraging the development of private hospitals, enlarging the coverage of medical services, and pursuing different policies for the provinces with higher GDP per capital and population density.

“…Built upon the basic DEA models of Charnes et al [27] and Banker et al [28], Tone [29] proposed the SBM to measure efficiency based on input excesses and output shortfalls. Being a non-radial approach, SBM overcomes the conventional radial DEA method's overestimating-limitation which is caused by neglecting slack variables [30]. Furthermore, SBM directly accounts for input and output slacks in efficiency measurements, with the advantage of capturing the whole aspect of inefficiency [24].…”

Little attention has been paid to international ecological efficiency, especially taking ecological footprint (EF), labor, and capital into account as multi-inputs to produce GDP in the total-factor framework. This study evaluates the total-factor ecological efficiency (TFEcE) of G20 during the period of 1999-2013 by employing slack-based measure (SBM) with EF as the index of comprehensive ecological inputs. Findings show that the average level of TFEcE of G20 from 1999 to 2013 is at a low level of about 0.54, which means there is a large space for the improvement of TFEcE. Furthermore, TFEcE of G20 is very imbalanced and there is a big gap between developed countries and developing countries in the G20. For the developing countries and developed countries in the G20, the analysis of factors that affect national TFEcE shows different statistical significance in the truncated regression model.
