Then, he proved the validity of the proposed model through the application of 48 steel enterprises in China during 2009–2013 [ 1 ]. Volis et al aimed to investigate and study the relationship between environmental innovation, environmental performance, and environmental productivity.…”

International environmental law is the basic charter for dealing with international environmental issues, and it plays an important role in international environmental governance. In recent years, China’s economy has achieved great development, but environmental problems are also very prominent. International environmental law provides a basic reference for China’s environmental governance, but it also brings challenges to the development of China’s environmental productivity to a certain extent. At the same time, due to the unique dominant position of international environmental law, it has played a certain restrictive role in the development of China’s environmental productivity. Based on this, in order to promote the sustainable development of China’s economy, this paper took China’s industrial and agricultural development as the research object. This paper has conducted research on China’s industrial and agricultural environmental productivity, aiming to explore the role of international environmental law in China’s environmental productivity. The article first analyzed the limitation of international environmental law on China’s environmental productivity, and then on this basis, the article conducted a numerical simulation of China’s industrial and agricultural environmental productivity. Finally, starting from the actual development situation, the paper aimed to find out the numerical deviation of China’s environmental productivity changes through quantitative analysis. In the course of the research on environmental productivity development, the article found a strong correlation between environmental productivity and international environmental law in China. The correlation between environmental productivity and international environmental law reaches 59.93% in South China and 61.02% in North China. Also, after a series of comparative analyses, the article finds that changes in climate characteristics can exacerbate the regulation of China by international environmental law and seriously affect China’s economic development. In this case, China’s economy declined by 2.6% year-on-year, which further pushed China to practice sustainable development strategies. This shows that it is essential to study the relationship between international environmental law and China’s environmental productivity.

“…In this paper, the performance change assessment of Ecuadorian petroleum companies is performed following the nonconvex pollution‐adjusted Malmquist (PM) and Hicks–Moorsteen (PHM) productivity indices (Abad & Ravelojaona, 2022, 2021). The PM productivity measure takes the form of the Malmquist index (Caves et al, 1982; Färe et al, 1995) while the PHM productivity measure inherits the structure of the HM index (Bjurek, 1996).…”

This paper assesses the performance of 20 Ecuadorian petroleum industry over the period 2014–2018, using the pollution‐adjusted Malmquist (PM) and Hicks–Moorsteen (PHM) productivity indices within a convex neutral analytical framework. Indeed, to the best of our knowledge, the environmental performance variation of the Ecuadorian oil industry has never been investigated hitherto in the literature. Moreover, the existing literature that analyses the environmental performance change of oil industries applied the Malmquist productivity index by considering a convex production set. However, the convexity assumption results in ignoring possible non‐linearities in the production process. Also, the performed PM and PHM in this paper are decomposed and disaggregated to provide the main drivers of both economic and polluting productivity change. Finally, the performance change assessment is carried out through a nonparametric enumerative method that is defined in the paper.

“…First, the Hicks‐Moorsteen TFP index is multiplicatively complete (O'Donnell, 2012). This permits separate analysis of output and input growth or decline, which can also be adapted to the environmental context (Abad & Ravelojaona, 2022). For our partial productivity formulations, this means that one can separately assess aggregate output change and energy use change, on the one hand, and GHG emission change and polluting input change, on the other hand.…”

“…The only alternative theoretical models that use a by‐production framework to model bad outputs in both convex and non‐convex ways are found in Abad and Briec (2019) and Abad and Ravelojaona (2021, 2022). These models are based on recent work to measure strong forms of hypercongestion for convex and non‐convex technologies in Briec et al (2016) who develop a limited form of strong disposability called S ‐disposability (see Briec et al (2018) for an empirical illustration).…”

The agricultural sector is currently confronted with the challenge to reduce greenhouse gas (GHG) emissions, whilst maintaining or increasing production. Energy-saving technologies are often proposed as a partial solution, but the evidence on their ability to reduce GHG emissions remains mixed.Production economics provides methodological tools to analyse the nexus of agricultural production, energy use and GHG emissions. Convexity is predominantly maintained in agricultural production economics, despite various theoretical and empirical reasons to question it. Employing nonconvex and convex frontier frameworks, this contribution evaluates energy productivity change (the ratio of aggregate output change to energy use change) and GHG emission intensity change (the ratio of GHG emission change to polluting input change) using Hicks-Moorsteen productivity formulations. We consider GHG emissions as byproducts of the production process by using a multi-equation model. Given our empirical specification, nonconvex and convex Hicks-Moorsteen indices can coincide under certain circumstances, which leads to a series of theoretical equivalence results. The empirical application focuses on 1,510 observations of Dutch dairy farms for the period of 2010-2019. The results show a positive association between energy productivity change and GHG emission intensity change, which calls into question the potential of on-farm, energy-efficiency-increasing measures to reduce GHG emission intensity.
