The spatial dynamics of oil flow, shaped by regional disparities in production and consumption, are manifested not only in the spatiotemporal evolution of large-scale, crossborder, and cross-regional oil trade networks and supply chains on a global scale but also in the power struggles involving various actors such as enterprises, governments, and trading centers. Current research predominantly analyzes the spatiotemporal evolution of trade networks and supply chains at the national (regional) level, lacking a comprehensive examination of the power dynamics and strategic coupling among different actors. To address this gap, this paper leverages the global production network theory to study the evolutionary characteristics and strategic coupling changes of Sinopec Jinling Company's crude oil and product oil production network between 1999 and 2021. The findings are as follows: (1) Crude Oil Production Network: In 1999, Sinopec Jinling Company's production network heavily relied on domestic crude oil. However, by 2021, a significant shift occurred, with most of the crude oil being imported from the Middle East, facilitated primarily through long-term agreements and spot crude oil trades. Singapore emerged as a crucial crude oil hub, gaining strategic importance within the Malacca Strait-South China Sea-Taiwan Strait corridor. (2) Refined Oil Production Network: The distribution focus of Sinopec Jinling Company's refined oil production network initially centered around central and southern Jiangsu in 1999. However, a "diversified" trend is now observed, with the government playing a substantial regulatory role in shaping the network's geography. (3) Strategic Coupling of Crude Oil Production Network: The strategic coupling of Sinopec Jinling Company's crude oil production network evolved from internal coupling in 1999 to interactive coupling in 2021. (4) Strategic Coupling of Refined Oil Production Network: In 1999, the refined oil production network was characterized by absolute dominance of internal coupling, but over time, it shifted towards relative dominance. This research sheds light on the dynamic transformations in the oil production network and strategic coupling mechanisms, emphasizing the role of global production network theory in understanding these complex interactions.
