The Efficiency of Green Technology Innovation and Its Influencing Factors in Wastewater Treatment Companies

To achieve the harmonious development of economic growth and the environment, nations must pay more attention to wastewater treatment and boost efficiency using green technology. This study applies the Malmquist-DEA model to assess the efficiency of green technology innovation in 19 Chinese wastewater treatment companies between 2017 and 2020. In addition, focus is placed on the core wastewater treatment technology of the companies with excellent performance, indicating how wastewater treatment companies may improve their green technology. The results of the study indicate that, first, the overall effectiveness of green technology innovation in companies follows a rising and then decreasing trend. In 2020, wastewater treatment companies’ green technology innovation efficiency was around 17.4 percent lower than in 2017. Improving technical progress is the key to boosting the total factor productivity of wastewater treatment companies. Second, based on the Tobit regression, the shareholding ratio of companies has a positive influence on the technical efficiency of companies. Therefore, China should increase innovation capacity and productivity, adopt current sewage treatment technology from overseas, and thus gradually achieve clean sewage utilization and ecological environment management.

Diversification of business and technical efficiency of companies in Vietnam

This study focuses on assessing the technical efficiency of enterprises across 63 provinces of Vietnam from 2015 to 2018 and the factors affecting their technical efficiency, in which we focus on two factors: business diversification and ICT index. In this research, we use the DEA method to group effective and ineffective enterprises, then use the GMM method to estimate the factors affecting to the firm’s performance. The research results show that the technical efficiency of enterprises in the provinces is quite small (about 10%), most of the enterprises have not achieved the technical efficiency due to the wasteful use of input factors. Research shows that business diversification and ICT both have a positive impact on efficiency, from which to increase technical efficiency, enterprises in provinces need to pay attention to business diversification and improve ICT index. in terms of the local government

Analýza využití strategie kooperace v oblasti textilního průmyslu

Cooperation between enterprises is the basis for industrial clusters' existence and developments, while it is embedded in the enterprises' social network. Cluster organizations are one of the tools to support performance and competitiveness. The article analyses the influence of the existence of a cluster organization in the textile industry on finance performance of its member companies. For research purposes, the companies were divided into two groups. The first group consisted of companies included members of the CLUTEX Cluster which represent an organized cluster. The second group consisted of companies that do business in the same geographic region as the organized cluster, but are not its members. The aim of the research was to verify the statement that enterprises that create the core of the cluster organization achieved higher financial performance than all other non-member enterprises in the same geographic region doing business in the same industry. The Wilcoxon-Mann-Whitney W test and Kolmogorov-Smirnov test were used to determine the difference between the research samples. The technical efficiency of companies in all these groups was examined using DEA Window Analysis for the period of 2009–2019.

Parametric and Non-Parametric Cost Efficiency Benchmarking of Water Utilities in Russia

The activities of the water companies in Russia are regulated in order to overcome market failures caused by regional monopolization, information asymmetries and the need to find a balance between the interests of consumers and company objectives for its normal functioning and development. In the Russian Federation, the regulator uses the outdated and inefficient cost method, which deprives the company an incentive to reduce their own costs. However, Russian regulator is in active discussion about the transition to modern long-term management regulation practices in order to increase companies’ efficiency, which in the framework of the regulation defines the future of the company's profits.Russian regulator should take more active steps to encourage regulated companies to increase efficiency and productivity. Solution is to move to using benchmarking, which allows to identify sources of companies’ inefficiency to assess the validity of the established tariffs. This study presents the first attempt to implement benchmarking methods used by the world's leading regulators to determine the cost efficiency of companies and improve their potential. The authors tested a parametric (COLS) and non-parametric (DEA) methods to assess the performance of companies with different technical and economic characteristics more accurately. The study makes a number of recommendations for the specification of the model, assessing its sensitivity to the changes in samples. The authors concluded that the model based on COLS is of high quality and resistance to changing of sample while assessing the technical efficiency. However, a similar statement for DEA models is unfair, since the inclusion in the analysis of either too large or too small companies does not lead to plausible results. On the other hand, DEA allowed to assess not only the technical efficiency of companies but also the allocative one.In general, the authors have shown that the potential for increasing the efficiency of Russian water supply companies is large enough, and the regulator is necessary to accelerate the transition to incentive regulation in order to increase efficiency in the sector.

Regulation, competition, crisis and technical efficiency of companies operating in Spanish ports (2002–2011)

This article analyses regulation, competition, crisis and technical efficiency of companies operating in Spanish ports in the following sectors: shipping agents, stevedoring, logistics and storage, towage, ancillary services for inspection, repair and maintenance of ships and goods and port terminals, over the period 2002–2011. The results show that port regulation during this period promoted greater efficiency among all port sectors. Furthermore, the work shows that competition and efficiency are highly scattered throughout the various port sectors, with some sectors showing very low technical efficiency, like stevedoring, operating alongside others with very high technical efficiency, such as services (inspection, repair and maintenance of ships and goods) and logistics operators. The work analyses the effects of the liberalisation introduced by Act 48/2003 of 26 November.
