摘要

The main purpose of this study was to comprehensively evaluate the marine resource utilization efficiency in China and reveal trends in regional differences. Resource intensity is the amount of resource consumption per unit gross domestic product. It is an important indicator in measuring resource utilization efficiency. We examined marine resource intensity (MRI) convergence for 11 coastal regions in China during 1996-2015 based on resource intensity and economic growth convergence theory. During the study period, MRI in China exhibited a decreasing trend. MRI differed significantly between different coastal provinces, which could be classified into three categories, namely low-, medium-, and high-intensity. Marine economic development, marine industry structure, degree of openness to the outside world, and scientific and technological capability significantly affected the decreasing trend in MRI, whereas the level of material capital investment had a negligible impact. MRI in China followed sigma- and absolute beta-convergence with a low convergence rate (0.14%). However, no conditional beta-convergence trend was observed. Global stochastic convergence could not be applied because a shock will have a continuous impact on MRI in more than 70% of the studied coastal provinces. In summary, policy intervention is essential for reducing the MRI gap between different provinces.
