供应链动态能力对油脂企业环境绩效的影响研究

党的二十大报告强调加快发展方式绿色转型,油脂企业作为传统加工企业,绿色转型是发展的必然方向。为了探究油脂企业如何在行业转型期复杂的外部环境下提升环境绩效,完成绿色化改造,研究构建了供应链动态能力、价值共创与环境绩效间的关系模型,并基于油脂企业的调研数据,利用结构方程模型检验供应链动态能力对环境绩效的影响作用,同时验证价值共创的中介效应,并基于研究结果提出管理启示。结果表明：供应链动态能力对环境绩效具有显著的正向作用;价值共创在供应链动态能力与环境绩效之间存在中介作用。油脂企业高质量发展需从战略高度注重企业动态能力的培养,积极开展价值共创活动,优化绿色供应链管理,多措并举提升环境绩效。     

Decision making in the cod industry based on recording and analysis of value chain data

The influence of catching and processing factors on fillet yield, gaping and number of nematodes in cod (Gadus morhua) was studied. The study was carried out in co-operation with four Icelandic fishery companies. Data on catch, condition of raw material and processing were linked together by tracing the cod from catch through primary processing. Analysis of these data show that important variables for profitability in the fish industry are strongly correlated to controllable variables, such as catch ground, catch method and age of raw material when processed. The results can aid in decision making for catching and processing cod, provided that strong relationship exist between different links in the value chain of cod.     

Building a sustainable supply chain: an analysis of corporate social responsibility (CSR) practices in the Chinese textile and apparel industry

This study aims to analyze the development, achievements, and challenges of corporate social responsibility (CSR) practices in the Chinese textile and apparel industry. The determinants of CSR movement in the industry are discussed. The World Bank CSR Diamond Model based on stakeholder theory provides an analytical framework to address this complex issue in a systematic way. The relevant information and data were gathered from an extensive literature review of governmental, industrial and academic publications, and interviews. Overall, the tightening legal environment for CSR development has raised the cost of doing business in China in a short time. While forward‐looking companies are already taking CSR into account in their daily operations and strategic plans, some resistance to the execution and enforcement of CSR‐related laws and regulations have been witnessed. However, from a long‐term perspective, the CSR movement will benefit towards upgrading the industry and the healthy growth of China's economy, and contribute to the sustainable global textile and apparel supply chain.
