PurposeThis study aims to examine the relationship between green supply chain management (Green SCM) practices and environmental performance, and develop an integrated model to explain the mediating role of ecocentricity on the relationship between Green SCM practices and environmental performance in the context of the Ghanaian downstream petroleum industry.Design/methodology/approachTo address the objectives of the study, a survey had been conducted among companies in the Ghanaian downstream value chain. The paper used the structural equation modeling approach and smart partial least squares (Smart-PLS) analytical tool.FindingsThe study revealed that Green SCM practices had a significant and positive relationship with supply chain ecocentricity and environmental performance. The study further revealed that supply chain ecocentricity significantly mediated the relationship between Green SCM practices and environmental performance.Practical implicationsThe study has developed a new integrated model to enhance oil and gas marketing and distribution company's adaptation and implementation of Green SCM practices.Originality/valueThe study had successfully applied the natural resource-based view and the stakeholder theory in the context of Ghana's downstream petroleum industry. Specifically, these theories had been integrated to form a new model to explain the relationship between Green SCM practices, supply chain ecocentricity and environmental performance in the context of Ghana's downstream petroleum industry. The newly developed integrated model has wider predictability as compared to the individual theories.

Purpose The purposes of this study are: to investigate how the dimensions of resource competitive strategies impact on small and medium enterprises’ (SMEs) intention to invest in Ghana’s downstream petroleum sector and to develop a model to explain the moderating role of local content policy on the relationship between competitive strategies and investment intention of SMEs. Focusing on the Ghanaian SMEs, quantitative research approach and survey questionnaire have been used. The research hypotheses have been tested using variance-based structural equation modeling technique. Design/methodology/approach Since the Ghanaian Parliament passed the Local Content and Local Participation Policy (LI.2204) into law in 2013, successive governments have strived to optimize oil and gas benefits and encouraged local participation, yet the actual impacts are mixed, ambiguous and inconsequential. This paper further argues that the extent to which the local content policy role moderates the relationship between firms’ internal resources (proxied as competitive strategies) and investment intention in the energy sector remains largely unexplored. Findings The results have shown that competitive strategies such as entrepreneurial competency, finance resources and technological usage have positive and significant effects on SME's investment intention. Again, local content policies exert significant moderating effect on SMEs’ investment intention. Practical implications The policy implication of these results includes the need to strengthen regulatory capacity of the Petroleum Commission to enforce local content implementation in Ghana to enhance indigenous participation in the sector. Originality/value Theoretically, using the resource-based view theory, this study has offered a robust predictability of SMEs investment’s determinants in an emerging economy.
