构建了城市广义梯度分布评价指标体系,利用主成分分析法求得广州及粤西—北部湾区域6城市的广义梯度分布综合指标,经比较得到如下结论:首先,在发达地区与欠发达地区之间,梯度推移是多维双向的;其次,在泛珠三角区域中,粤西—北部湾属于塌陷区域;第三,在粤西—北部湾区域6城市中,湛江又属于高梯度城市。湛江市具备了带动雷州半岛实施广义梯度发展的基础,有望成为粤西—北部湾乃至广东省的新经济增长极。在对雷州半岛经济崛起动力条件分析的基础上,提出了“东联西融、蓝色崛起”的发展战略及相关对策。
The index system of generalized gradient distribution in city is established, and the generalized gradient distribution index of six cities in Guangzhou and western Guangdong - Beibuwan area is calculated by principal component analysis. The conclusions as follows are obtained: First, in developed and underdeveloped areas Second, in the Pan-Pearl River Delta region, the western Guangdong-Beibu Gulf belonged to the subsidence area. Third, Zhanjiang belonged to the high-gradient city in the six western Guangdong-Beibu Gulf areas. Zhanjiang City possesses the basis for promoting the development of generalized gradient in Leizhou Peninsula and is expected to become the new pole of economic growth in western Guangdong, Beibu Gulf and even Guangdong Province. Based on the analysis of the motive power of the economic rise of Leizhou Peninsula, this paper puts forward the development strategy and countermeasures of “the development of the East and the West, the rise of blue”.
