[Abstract] Against the background of in-depth adjustment of the global economic structure and the in-depth transformation and upgrading of the manufacturing industry, the supply chain has become a key carrier of the core competitiveness of small and medium-sized manufacturing enterprises. As a major manufacturing hub in China, the Pearl River Delta region has a large number of small and medium-sized manufacturing enterprises that, due to constraints such as management concepts and cost pressures, still have problems such as a single structure and lack of incentives in the salary incentives for core supply chain positions, which seriously affect supply chain efficiency and talent stability. Taking Dongguan XH Precision Connector Manufacturing Enterprise as the research object, combined with the author's 25 years of manufacturing experience and 8 years of supply chain management consulting experience, this paper systematically diagnoses the salary incentive status of its three core positions: planning, procurement, and warehousing, using literature research, field investigation, questionnaire survey, and interview methods. The research finds that XH Enterprise's salary system is mainly based on fixed wages, with core problems such as rigid structure, insufficient internal fairness, weak market competitiveness, and lack of collaborative incentives, leading to low employee enthusiasm and high talent turnover rate. Based on classic theories such as Equity Theory and Expectancy Theory, and combined with the particularities of salary
incentives in small and medium-sized manufacturing enterprises, this paper designs a ternary salary structure of "basic salary + performance salary + collaborative reward", supporting a differentiated KPI system and dynamic adjustment mechanism, and constructs an implementation guarantee system from three dimensions: system, organization, and culture. This research aims to solve the actual management dilemmas of XH Enterprise, provide operable practical references for the optimization of salary incentives for core supply chain positions in similar small and medium-sized manufacturing enterprises, and help enterprises improve supply chain management efficiency and market competitiveness.
