Although numerous studies examine the impacts of environmental compliance and innovation on a firm’s economic performance, the role of export activities in this nexus has remained unanswered. In this study, we revisit the Porter hypothesis by investigating synergy strategies of different environmental and economic practices (i.e. environmental compliance, product innovation, process innovation and having export activities) on total factor productivity (TFP) of Vietnamese manufacturing SMEs.

This study applies Value-Belief-Norm (VBN) theory to investigate fishers' pro-environmental behavioral intention and their support for policies to reduce marine litter. While pro-environmental behavioral intention is often associated with personal environmental intention at the household level, policy support represents their support for government action at the political level. Therefore, we examine whether fishers are willing to engage in both of these dimensions. Data from 369 Vietnamese fishers are analyzed using structural equation modeling with FIMIX-PLS and PLS-POS.

Water pollution poses a critical challenge, especially in fast-growing regions, with profound implications for human well-being. Marginal abatement cost (MAC) estimation is crucial for designing efficient water pollution controlpolicies.
