摘要
京汕低谷带在全国经济发展由东向西战略转移过程中具有承东启西的重大责任,研究京汕低谷带经济发展差异具有重要现实意义。首先,将京汕低谷带作为整体,考量了21世纪以来其在全国经济发展格局中地位的演变,发现其经济总量、均量在全国地位变化可分为快速下降和波动性缓慢下降两个阶段,发展速度亦处于劣势,客观上证实了经济低谷的存在;其次,以市域为研究单元,对低谷带内部经济综合发展差异做进一步的时空演变分析,结果表明:低谷带市域经济发展差异在时序上呈不断增大态势,尤其是绝对差异;市域经济发展水平的空间差异十分明显,各发展类型区域在空间分布上以"组间分异,组内集聚"为主要特征;低谷带各城市经济发展水平整体上提升缓慢,陷入到"有点无轴"的发展困境。最后,基于京汕低谷带的发展困境进一步探讨了促使其经济振兴的政策措施。
Jing- Shan economic trough belt takes the responsibility of national economic development strategic shifting from east to west. It is of great practical significance to research the economic development disparities of Jing- Shan economic trough belt. Firstly, taking Jing-Shan economic trough belt as an entirety, this paper analyzed the evolution of its status in national economic development since 2000, and found that the status of its total GDP and per capita GDP declined continuously which contains rapid decline phase and fluctuating slow decline phase, and the development speed was also at a disadvantage, that objectively confirmed the ~,xistence of trough economy. Secondly, with municipality as research unit, the disparities of comprehensive economic ti~.＇vclopment inside the trough belt were further discussed from the perspective of spatial-temporal evolution. Results shc~ that： The municipal economic disparities have expended in Jing-Shan economic trough belt since 2000, especially the absolute disparities. Then, the spatial disparities of municipal economic development level are evident, and areas with various development types are characterized with ＂differentiation between groups and clusters within the group＂ on spatial distribution. Besides, the majority of cities in Jing-Shan economic trough belt have no obvious promotion on economic development level, getting into the dilemma of ＂with pole but no axis＂. Finally, we put forward the corresponding optimization countermeasures based on the development dilemma of Jing-Shan economic trough belt at present.
