The Impact of Logistics and Supply Chain Management on the Sustainable Growth of Shenzhen's Cross-Border E-commerce: The Mediating Role of Trust

Abstract

This study investigates the intricate relationship between logistics and supply chain management, consumer trust, and the sustainable growth of cross-border e-commerce enterprises in Shenzhen, China. As a global hub for manufacturing and trade, Shenzhen's cross-border e-commerce sector has experienced exponential growth, yet faces significant challenges in achieving long-term sustainability amidst fierce competition and rising consumer expectations. This paper posits that the operational effectiveness of logistics and supply chain management is a fundamental driver of sustainable growth, not merely through cost and efficiency gains, but more critically, through its role in building consumer trust. Using a quantitative approach, survey data was collected from 350 consumers with recent cross-border purchasing experiences from Shenzhen-based firms. The study measures three core constructs: Logistics and Supply Chain Performance (LSP), Consumer Trust, and Sustainable Growth (measured via customer loyalty and repurchase intentions). Statistical analysis, including descriptive statistics, correlation analysis, and mediation analysis using structural equation modeling, was employed to test the proposed hypotheses. The findings reveal a strong, positive correlation between LSP and sustainable growth. More importantly, the results of the mediation analysis confirm that consumer trust plays a significant mediating role in this relationship. The indirect effect of LSP on sustainable growth via trust is statistically significant, suggesting that the true value of an efficient supply chain lies in its ability to foster a reliable and secure customer experience, which in turn cultivates the loyalty essential for long-term success. This paper contributes to the literature by empirically validating trust as a key mechanism through which operational capabilities are translated into sustainable competitive advantage in the cross-border e-commerce context. The findings offer practical implications for managers, highlighting the need to strategically invest in logistics infrastructure and transparent processes as a means of building brand equity and ensuring enduring growth.
