Social security expenditure, as a key component of human resource costs in private enterprises, significantly influences operational efficiency and regional economic vitality. This is acutely relevant in the textile industry, given its large labor force, where optimizing these human resource factors directly affects the overall productivity and operational scale of manufacturing centers. This study examines the relationship between the total social security contributions for urban employees and human resource costs in private enterprises in Foshan City from 2010 to 2024. Using regression analysis, a quantitative model is constructed to reveal the impact mechanism. Results indicate a significant positive correlation: a 1% increase in social security contributions leads to a 0.62% rise in labor costs, with a stronger effect in labor-intensive industries. Policy and managerial implications are discussed to support cost optimization and sustainable development. These insights are crucial for guiding the textile industry in balancing necessary workforce investments with the efficiency required for sustainable, long-term operation of manufacturing facilities.
