metafrontiers always envelope the estimated group frontiers. Keywords: Metafrontier analysis; Convex and non-convex metatechnologies; Stochastic.

The metafrontier framework proposed by O'Donnell et al. enables the evaluation of relative efficiencies for decision‐making units (DMUs) operating under heterogeneous technologies.

E-mail: tomas.balezentis@evaf.vu.lt. ORCID 0000-0002-3906-1711 Abstract. The productive technology can be defined for different levels of aggregation (e.g., … The contemporaneous productivity, metafrontier productivity and TGR scores for all the DMUs are summarized in Table 8, in which the metafrontier productivity scores were measured without considering the nationality of shipyards. A TGR score is the ratio between the corresponding contemporaneous and metafrontier productivities.

De Witte and Marques (2009) formed a combination between the FDH model and metafrontier function. A metafrontier slack-based efficiency measure is presented to measure environmental efficiency for various regions in China. The objective of the new approach is to investigate the change of environmental efficiency while incorporating group heterogeneities and all variable slack and environmental pollutants into environmental efficiency analysis. A metafrontier approach for measuring an environmentally sensitive productivity growth index Oh, Dong-hyun KTH, School of Architecture and the Built Environment (ABE), Centres, Centre of Excellence for Science and Innovation Studies, CESIS. The group innovative provinces have set a target for resource utilization of non-innovative provinces in order to catch-up with the corresponding groups, while the metafrontier innovative provinces provide targets for the technology levels of other provinces to improve their green development performance. This paper considers a stochastic metafrontier function to investigate the technical efficiencies of firms in different groups that may not have the same technology.

The frontiers were divided into five regions; Bangkok, central,  The metafrontier model enables the calculation of comparable technical efficiencies for firms operating under different technologies. The model also enables the  Keywords: China's grain production, county-level, metafrontier, stochastic production frontier, technical efficiency.

The rest of this study is organized as follows. In Section we introduce the 2, Nguyen, Hong-Oanh (Owen), Nghiem, Son, & Chang, Young-Tae (2018) A regional perspective of port performance using metafrontier analysis: the case study of Vietnamese ports.

three analytical frameworks are applied: (1) a technical efficiency comparison over time, (2) a metafrontier approach among mergers and non-mergers, and (3)​ 

model is possible as long as we can identify separate frontiers for For example, if a particular output, y, can be produced using input different groups in the data set (O’Donnell et al., 2007). As the analyzing method, the stochastic frontier is used as well as the metafrontier. According to the frontier function scores in the subsectors, in small-scale firms MP, FDT and MEMSAS subsectors and in medium- and large-scale firms OCP, FDT and TSL subsectors are the most efficient subsectors.

In other words, the metafrontier model is The use of the DEA methodology to construct the metafrontier considered as an envelope of all the possible group technologies. model is possible as long as we can identify separate frontiers for For example, if a particular output, y, can be produced using input different groups in the data set (O’Donnell et al., 2007). This paper uses directional distance functions to extend the non-parametric metafrontier approach to efficiency measurement proposed by O’Donnell et al.

metafrontier framework because of its ability to estimate the technology-gap ratios, in addition to estimated parameters of frontiers and technical inefficiencies. The stochastic metafrontier framework proposed by Battese and Rao (2002) and Battese et al. (2004) is followed in this analysis. Analogous to Battese et al.

The metafrontier model is used to highlight heterogeneity among clusters of countries revealing catch up phenomena. The estimation procedure is based on the notion of stochastic ordering and relies on the solution of an optimization problem on the parameters’ posterior means.
