This study is intended to expose the connectedness of green financing and other green policies like renewable energy and technological progress towards identifying the best practice to achieve climate goal cum sustainable environmental development for China within the period 1985–2021. Amid the increased utilization of fossil fuels in China's economic activities and its position as the highest carbon emitting country in the world, China is considered a financial stable economy with access to renewable energy source such as hydroelectric power. For effective research into the objective of this study, the study builds on mechanism of the green finance—renewable—technology and emission nexus with the help of linear dynamics of ARDL bound and VECM granger causality methods. Empirical results from both approaches have given insight to the selected objectives of this study. According to ARDL dynamics: (i) the coefficients of linear (1.802) and non-linear(− 1.860) (i.e. square term) of financial development are positively and negatively connected to the carbon emissions. This confirms the presence of inverted U-shape relationship between the financial development and carbon emissions. (ii) the relationship between hydroelectric power representing renewable energy and CO2 is negative—(− 0.19) and significant at 1% level. This results depicts the reduction power of hydroelectric power on CO2, (iii) also, a negative (− 0.000982) linkage between number of patent application representing technological innovation and environmental development through carbon emissions responses is established. Also, findings from VECM granger causality approach back the findings from ARDL through a nexus between the variables of interest (finance, hydroelectric power, and technology and carbon emissions). Findings point to the ability of green financing to reduce carbon emissions if green financing policies are utilized effectively in regulating carbon emissions. [ABSTRACT FROM AUTHOR]

In this study, changes in total factor productivity of 12 Korean offshore fisheries between 1997 and 2009 were estimated through the Malmquist productivity index, which is a nonparametric method. Also, the cause of such changes in productivity of each fishery was analyzed more specifically by segmenting into factors for technological progress and technical efficiency. As a result of this analysis, the total factor productivity change of the entire offshore fisheries was −6.0 %. Changes in the technical efficiency and technological level factors, respectively, contributed 0.2 and −6.2 % to this rate of decrease in total factor productivity; that is, inactivity of technological progress led to the decrease in productivity of the offshore fisheries. In addition, technological progress and technical efficiency were found to differently influence the change in total factor productivity of each fishery. In order for each fishery to improve productivity, better rational fisheries management policies by the government and efforts by the fishing industry and individual fishing business units must accompany factors that promote productivity increase.

This study investigates the effect of a CO2 tax on profitability by using firm-level data on output and inputs from Swedish industry between 1990 and 2004. The purpose of this exercise is to investigate the validity of the so-called Porter hypothesis. By utilizing a factor-demand modeling approach, and specifying a profit function that has a technology component dependent upon firm-specific effective tax on CO2, we are able to separate out the effect of regulatory pressure on technological progress. The results indicate that there is evidence of a “reversed” Porter effect in most industrial sectors, especially in energy-intensive industries; that is, after controlling for the fuel price effect, technological progress and consequently profits are further negatively affected by the CO2 tax.
