中文摘要:
      在区域经济发展过程中,空间极化与空间经济网络发育共进,多个增长极与空间经济网络有机结合和共生形成多极网络空间组织。实施长江经济带发展战略,要把构建和优化多极网络空间发展格局作为一个重点。基于“经济网络—多增长极—共生关系”的分析框架,利用2000—2017年A股上市公司的总部—分支数据构建长江经济带空间经济网络,通过节点度、网络密度、点度中心度、网络连通度等分析其发育水平,并根据城市综合指数(标准化后的节点度与规模加权经济增长率之和)判定增长极范围及其核心城市,进而运用共生度模型检验增长极与空间经济网络之间的共生关系,结果发现:长江经济带的空间经济网络发育水平稳步上升并趋于成熟,同时已形成长三角、长江中游、成渝三大增长极;三大增长极之间的经济联系持续增强,其中,长三角增长极与长江中游增长极的联系强度最大,长三角增长极与成渝增长极次之,而长江中游增长极与成渝增长极的联系强度较小;增长极与空间经济网络之间存在正向非对称互惠共生关系,增长极对空间经济网络的促进大于空间经济网络对增长极的促进,空间经济网络对增长极的促进作用不断增强,而增长极对空间经济网络的促进作用呈现先减弱后增强的趋势。可见,多极网络空间组织在长江经济带已初步形成,应在进一步推动三大增长极加快发展的同时,加强增长极之间的互动,建立多维度多层次的更加紧密的空间经济联系,提升空间经济网络的现代化水平,促进长江经济带多极网络空间发展格局的持续优化。
英文摘要:
      In the process of regional economic development, spatial polarization advances with the development of the spatial economic networks, and multiple growth poles organically combine and coexist with spatial economic networks to form a multi-polar network spatial organization. To implement the development strategy of the Yangtze River Economic Belt, the construction and optimization of the multi-polar network development pattern should be a key point. Based on the analysis framework of “economic network-multiple growth poles-symbiotic relationship”, the spatial economic network of the Yangtze River Economic Belt was constructed by using the headquarters-branch data of A-share listed companies from 2000 to 2017, and its development level was analyzed through node degree, network density, point degree centrality, and network connectivity. According to the comprehensive urban index (the sum of standardized node degree and scale weighted economic growth rate), the range of growth pole and its core cities are determined, and the symbiotic relationship between growth pole and spatial economic network is tested by symbiotic degree model. The results show that: the development level of spatial economic network in the Yangtze River Economic Belt increases steadily and becomes mature, and has formed three growth poles in the Yangtze River Delta, the middle reaches of the Yangtze River and Chengdu-Chongqing; the economic connection between the three growth poles continues to strengthen, among which, the connection intensity between the growth pole in the Yangtze River Delta and the growth pole in the middle reaches of the Yangtze River is the largest, followed by the growth pole in the Yangtze River Delta and the Chengdu-Chongqing growth pole, while the connection intensity between the growth pole in the middle reaches of the Yangtze River and the Chengdu-Chongqing growth pole is small; there is a positive asymmetric reciprocal symbiotic relationship between the growth pole and the space economic network, the promotion of the growth poles to the space economic network is greater than the promotion of the space economic network to the growth poles, the promoting effect of the space economic network on the growth pole is constantly increasing, and the promoting effect of the growth pole on the space economic network shows a trend of weakening at first and then increasing. It can be seen that: a multi-polar network spatial organization has taken shape in the Yangtze River Economic Belt; While further promoting the accelerated development of the three growth poles, we should strengthen the interaction between the growth poles, establish a multi-dimensional and multi-level closer spatial economic connection, improve the modernization level of the spatial economic network, and promote the continuous optimization of the spatial development pattern of the multi-polar network in the Yangtze Economic Belt.
