借助Bootstrap-DEA模型综合测算了环渤海地区17个城市海洋经济效率,并结合标准差椭圆和重心坐标方法,定量刻画了2000~2012年环渤海地区海洋经济效率空间格局演化特征,考察了影响空间格局演化的重要因素及其影响机制。结果表明:①基于Bootstrap-DEA模型纠偏后的海洋经济效率更低,但准确性更高;计算得到的环渤海地区海洋经济效率总体上且呈现先上升后下降的趋势,低海洋经济效率的城市主要分布于渤海西南沿岸。②从标准差椭圆分布来看,海洋经济效率总体呈现南(偏西)-北(偏东)的空间格局;从重心的移动轨迹来看,效率重心先向渤海西南部海洋经济区移动,再转向辽东半岛海洋经济区与渤海西部海洋经济区移动,最后转向山东半岛蓝色经济区移动。③针对海洋经济效率空间格局演化驱动机制的分析表明,区位优势对海洋经济效率产生正向影响,海洋产业结构和外商直接投资对海洋经济效率产生负向影响,资源消耗型海洋产业比重过大是导致海洋经济效率下降的主要原因。 |

By using Bootstrap-DEA model, this article first comprehensively measures and calculates the marine economic efficiency of 17 coastal cities in Bohai Sea Ring Area. Then Standard Deviation Ellipses and Barycentric Coordinates Method are applied to projecting and visualizing the evolution of spatial pattern of marine economic efficiency in Bohai Sea Ring Area from 2000 to 2012. Finally, we analyze the important factors which affect the evolution of spatial pattern and its mechanisms. Results are shown as follows: 1) Compared with the traditional DEA model, marine economic efficiency modified by Bootstrap-DEA model is lower but higher accuracy. Overall, marine economic efficiency in all the cities show a trend which first upwards and then downwards, and the cities with low marine economic efficiency are mainly located in northwestern BSRA. 2) Viewed from rotation angle of the Standard Deviational Ellipses, marine economic efficiency generally present a North (by east)-South (by west) spatial distribution pattern. Viewed from the track of the center of gravity, the center of gravity of marine economic efficiency first moves to Bohai Sea Southwest Marine Economic Zone, and then turns to Liaodong Peninsula Marine Economic Zone and Bohai Sea Western Marine Economic Zone, finally moves to Shandong Peninsula Blue Economic Zone. 3) By analyzing the evolution driving mechanism of spatial pattern of marine economic efficiency, we can find out that location advantages have positive impacts on the marine economic efficiency, while the marine industrial structure and FDI have a negative effect on marine economic efficiency. A large proportion of resource consuming marine industry is the main reason to reduce marine economic efficiency. |
