中国绿色发展的空间网络结构研究

利用中国30个省份(不含西藏和港澳台地区)的2016年绿色发展指数,构建修正引力模型,采用社会网络分析方法对中国绿色发展的空间网络结构特征进行的研究发现:2008—2016年中国绿色发展水平提升显著,地区间差异在缩小但差异仍较为明显,且地区间的联系突破地理邻近效应,呈现为广泛复杂的网络关联和结构形态并趋于稳定。绿色发展空间分布呈现:以环渤海为主的“双向溢出”板块,主要体现出经济及技术外溢以及能源输入;以西南地区为主的“双向溢出”板块主要进行资源供给及接受技术外溢;以东部沿海省份为主的“主受益”板块,体现其绿色发展得益于西北及环渤海地区的资源供给,各指标水平较高且均衡,但板块外的溢出效应不明显;西北地区省份为主的“净溢出”板块,各方面发展均比较落后,主要对环渤海地区进行资源供给;陕西、河南作为资源密集型省份,其绿色发展受自身经济、产业结构等因素的限制,但因其地理位置居中,处于网络中心性最高的重要地位,与其他省份存在较广泛密切的联系,建议培育为新的绿色发展增长极;总体上,板块内部聚类明显,但仍存在板块内部分省份及板块间的互动不强,需打破行政壁垒,发挥自身优势,促进板块间的技术、人才交流及资金流动,实现绿色协同发展。

Research on the Spatial Network Structure of Green Development in China

Based on the 2016 Green Development Index of 30 provinces(excluding Tibet,Hong Kong,Macao and Taiwan)in China,a modified gravity model is constructed,and the spatial network structure characteristics of Chinese green development are explored by using the social network analysis method.The results show that from 2008 to 2016,the level of green development in China has been significantly improved,and the differences between regions are narrowing,but the differences are still significant.Moreover,the links between regions break through the geographical proximity effect,presenting extensive and complex network connections and structural forms,and tend to be stable.The spatial distribution of green development presents as follows:the“two-way spillover”plate in the Bohou Rim region,which mainly reflects economic and technological spillover and energy input.The“two-way spillover”plate,mainly in Southwest Region,mainly provides resources and receives technology spillover.The“main benefit”plate,which is dominated by the eastern coastal provinces,reflects that its green development benefits from the resource supply in the Northwest Region and Bohai Rim Region.All indicators are relatively high and balanced,but the spillover effect outside the plate is not obvious.The“net overflow”plate,dominated by provinces in the Southwest Region,is relatively backward in all aspects of development and mainly supplies resources to the Bohai Rim Region.As resource-intensive provinces,Shaanxi and Henan are restricted by their own economic and industrial structure.However,due to their geographical location,they are in the middle of the network centrality and have extensive and close links with other provinces.It is suggested to cultivate them as new growth poles of green development.On the whole,the intra-plate clustering is obvious,but there are still some provinces within the plate and the interaction between the plates is not strong,need to break down administrative barriers,give play to their own advantages,promote inter-plate technology,talent exchange and capital flow,to achieve green collaborative development.
