The present work is an attempt to investigate the adoption of sustainable supply chain management (SSCM) practices amongst manufacturing and process based organisations in India and its impact on organisational performance encompassing all three dimensions of sustainability. SSCM practices conceived in the present study include environmental management practices (EMP), socially inclusive practices for employees (SPE), socially inclusive practices for community (SPC), operations practices (OP) and supply chain integration (SCI) which were treated as exogenous variables. Organisational performance considered in this study includes five dimensions, namely environmental performance (EPR), employee-centred social performance (ESP), community-centred social performance (CSP), operations performance (OPR) and competitiveness, which were regarded as endogenous variables. The analysis was carried out with the help of structural equation modelling considering natural logarithm of manpower as a control variable. Few major findings are mentioned. EMP does not have any significant association with OPR, nor does it result in competitiveness. However, when jointly mediated through both EPR and OPR, EMP leads to competitiveness. SPC has significant negative association with competitiveness, when only direct relationship is considered. However, indirect relationship between SPC and competitiveness shows significant positive association when mediated through CSP. The resultant total effect between SPC and competitiveness turns out to be insignificant. Further, OPR fully mediates the relationship between OP and competitiveness. Managerial implications of the findings are discussed. 相似文献

In transitioning to a renewable material-based bio economy, growing public and industry interest is apparent for using wooden multistory construction (WMC) as a sustainable urban housing solution in Europe, but its business implications are not well understood. In our study, we evaluate, which internal and external factors of competitiveness are shaping the future of WMC, especially in the context of Finland and Sweden. Based on a multi-level perspective of socio-technical transitions, we conducted a three-stage dissensus-based Delphi study. The identified internal and external factors affecting the future competitiveness of the WMC business emphasize the importance of skilled architects and builders and the role of standardized building systems. Based on our results, the key aspects influencing the future competitiveness of WMC in the region are related to the development of technical infrastructure and project-based business networks, while additional changes in regulatory framework are perceived as less important. We conclude that towards 2030, the strong cognitive rules founded in the concrete-based building culture in these countries is likely to inhibit the dynamics of the socio-technical regime level. A change is also needed in the WMC business culture towards more open cross-sectoral collaboration and new business networks between different-sized players. 相似文献

长沙是湘绣的发源地,集湘绣的研发、生产、销售于一体,拥有着独特的湘绣文化。太平街坐落于长沙市老城区南部,是一条商业繁荣、游客众多的文化老街,主要以销售长沙当地特产、传统手工艺品、特色小吃等为主,极具湖湘文化魅力,吸引了许多外来游客。笔者以太平街为研究范围,对太平街区域内的湘绣销售情况进行了问卷调查,调查显示,太平街区域内的湘绣产品销售情况与湘绣产品的种类和游客群的构成特征关系密切。基于上述调查结果,笔者对当下的长沙地区湘绣销售的前景和未来湘绣文化产品的推广,进行了分析并提供了新的思路。 相似文献

Indicators of Small Town Tourism Development Potential: The Case of Fouriesburg, South Africa 总被引:1,自引:0,他引:1
As small towns experience economic and social restructuring, many are pursuing tourism opportunities as one component of a
more diversified local economic strategy. This paper is interested in the small town of Fouriesburg in South Africa's Free
State. While the town was once a thriving service center for a surrounding rural agricultural region, this traditional economy
has faded. Given that the nearby town of Clarens has developed a substantial tourism economy, we pose the question of whether
there already exist indicators that Fouriesburg may be poised for a similar change. These indicators include location within
the urban field, timing within the tourist area life cycle model, differentials/opportunities in property values, and the
role of real estate agents as “gatekeepers” in directing investments. The findings suggest that, while Fouriesburg has potential
for developing a tourism-oriented economy, many of the important policy and planning supports needed to assist with diversification
are not yet in place.
