Spatial Pattern Evolution and Industrial Characteristics of Economic and Technological Development Zones and High-tech Industrial Zones in China

Economic and technological development zone and high-tech industrial zone are important types of development zone in China,and there are differences in their connotation and goal setting.In this paper,basic data of national and provincial economic and technological development zones and high-tech industrial zones in China were collected and arranged.Kernel density analysis and other GIS spatial analysis techniques were used to analyze the evolution laws of spatial patterns of economic and technological development zones and high-tech industrial zones in cities from 2006 to 2018.First,the agglomeration intensity was compared by measuring the degree of regional agglomeration and dispersion on the two time nodes.Next,kernel density method was used to explore the evolution of the two in the spatial layout and location,and analyze development commonness and difference of economic and technological development zones and high-tech industrial zones.Finally,the trend and reason of spatial evolution of development zones with different leading industries were explored.Research results show that:①the agglomeration degree of layout of high-tech industrial zones is stronger than that of economic and technological development zones,and there are similarities and differences in distribution trend of spatial patterns of the two types of development zones;②the distribution of labor-intensive,capital-intensive and technology-intensive development zones is concentrated at smaller scales and dispersed at larger ones;③although there are differences between the economic and technological development zones and the high-tech industrial zones in the goal,support,structure and function,management system and so on,their spatial development presents a trend of convergence.In the future,when enhancing urban-rural planning and public administration,governments should combine the trend of industrial transformation and upgrading,and optimize spatial layout of development zones by adjusting industrial structure,layout,transportation and land use.

A Study of the Industrial Development in Huazhong Agricultural High-tech Industrial Development Zone

This paper illustrates the current situation and problems concerning the industrial structure in Huazhong Agricultural High-tech Industrial Development Zone,and analyzes the internal contradictions that exist in industry: small-scale land operation has become an inherent obstacle to the industrial development in Agricultural High-tech Zone; farmers are always in a passive position in industrial restructuring optimization; government's policy failures and rent-seeking behaviors have hindered industrial development; the research,popularization and application of agricultural science and technology is not suited to industrial development requirements. Finally,this paper makes the corresponding recommendations for industrial development in Huazhong Agricultural High-tech Industrial Development Zone.

Planning mode and realization path of regional characteristic ecoindustrial park

Starting from the regional characteristic industrial park planning plan,a horizontal comparison of domestic and foreign typical urban regional industrial park planning cases is carried out,and the commonalities characteristics are analyzed to explore the regularity and universality of the Tonghua urban characteristic industrial park.Under the guiding principles for planning and development of ecological industrial parks,the city’s resource advantages,industry goals and positioning are studied and analyzed from the perspectives of the government,market,and enterprises.It is pointed out that the government should formulate policies,regulations and the construction of characteristic industrial parks in combination with new planning methods.The market should build industrial parks with the support of industrial stimulus and technological innovation.Finally,it summarizes the realization path of regional characteristic industrial parks from five aspects:positioning and goals,ways to achieve goals,profit models,customers and values,basic advantages and exclusive resources.

长沙市开发园区工业企业用地节约集约利用研究

构建评价指标体系综合评价长沙市开发园区工业企业用地的集约利用程度,为园区土地集约利用提供决策依据。采用AHP方法和综合指数评价方法对长沙市开发园区工业企业用地的集约利用程度进行评价。结果表明:长沙市开发园区工业企业用地的集约利用整体水平较高,行业间差异明显;容积率和建筑密度偏低是影响长沙市开发园区工业企业节约集约利用水平的最主要因素。通过健全用地批后监管,严格工业企业用地准入机制;完善土地市场机制、提高土地利用率;加强企业技术创新等措施促进开发园区工业用地节约和集约利用。

长株潭高新区发展环境综合评价

采用多层次模糊综合评价方法对长株潭高新区发展环境进行综合评价,揭示了长株潭高新区发展中存在的主要问题:产业整体规模偏小,发展水平偏低;外向度低,国际竞争力弱;技术创新能力仍显不足;投资环境有待进一步完善。在此基础上提出了优化长株潭高新区发展环境的对策。

基于产业差异的长沙高新区企业用地效益研究

在以高质量发展、质量和效益为核心的亩均效益评价机制和开发区土地集约利用评价及相关研究的基础上,从企业微观层面进行开发区不同产业企业用地效益评价,为政府管理低效用地提供依据。采用目标值法对原始数据进行无量纲化处理,借用层次分析法和熵值法确定权重,应用综合评价法确定企业评价值,使用自然间断点法将用地程度分为低效、一般、适度和高效四个区间。结果显示:评价得分均值最高为新一代信息技术,电力装备评价得分均值最低和低效利用占比最多,工程技术低效用地占比最少,新材料一般利用占比最多,生物医药及高性能医疗器械适度利用占比最多,节能环保高效利用占比最高;六类产业用地程度在四个区间分布较均衡,一般利用和适度利用为最主要土地利用类型;产业间与产业内的企业土地利用效益差距显著,产出强度和税收是用地效益差异的关键。文章据此提出建议:建立企业管理数据库;运用微观层面的评价体系,并依据产业均值进行用地指标调整;产业升级与产业链完善,是推进工业用地高质量利用的有效路径。

城市群、产业集群与开发区互动发展研究——以长株潭城市群为例

城市群、产业集群与开发区的协同发展是实现城市群地区可持续快速发展的重要手段。在已有文献研究的基础上,基于宏观与微观相结合的视角,梳理了城市群、产业集群与开发区三者之间的关系及互动机制。认为城市群是新型城镇化的主体形态,是产业集群和开发区发展的空间载体,城市群为开发区和产业集群发展提供生产要素、服务和市场;开发区是城市群的创新创业高地与产业集聚、集群发展的重要场所,是城市群的重要生产功能区;产业集群是产业发展的重要组织形式,是推动开发区和城市群发展的重要驱动力。产业集群与开发区共享着城市群的资源与服务,开发区通过产业集聚与创新,产业集群通过产业链延伸、耦合与创新,与城市群形成生产要素、市场交易、创新与服务等方面的多维度相互作用,最终实现三者的协同发展。基于城市群、产业集群与开发区规模、结构、职能和创新等4个方面的17个指标,采用典型相关分析法,以长株潭城市群为案例区,对城市群、产业集群与开发区两大变量组进行了互动因素与强度的量化分析,结果表明:(1)长株潭城市群、产业集群与开发区已形成有效互动。其中,城市群通过经济规模、城市结构、创新投入与产出、服务职能的发展,促进产业集群的经济规模、产业集聚、经济效益与产业创新,以及开发区的建设品质、产业集聚与产业效率的发展。开发区通过产业集聚与创新效率的提高,产业集群通过产业规模、效益协同开发区效率的提升,强化了城市群规模、结构、创新与职能的发展。(2)长株潭城市群通过经济规模、结构、创新与服务四类因子,对产业集群与开发区产生了全面的促进作用,但产业集群与开发区并未完全协同地促进城市群发展。(3)要进一步提升产业集群的效益与开发区的效率,加强其对城市群发展与繁荣的支撑作用,全面实现三者的多维良性互动,提高城市群的核心竞争力。

城市群—开发区—产业集群协同发展研究——以长株潭城市群为例

运用复合系统协同度模型和CRITIC赋权法，从城市群子系统、开发区子系统、产业集群子系统中选取36个评价指标，测度长株潭城市群一开发区一产业集群各子系统有序度及整体协同度，并分析三者协同发展的形成机制。研究表明，长株潭城市群一开发区一产业集群复合系统协同水平总体上不断上升，目前处于初级协同阶段；城市群与产业集群、城市群与开发区两两之间的协同度呈同步上升态势，开发区一产业集群子系统协同状况较好，已进入良好协同阶段。在城市群范围内，在市场力和政府力的耦合作用下，开发区内部和开发区之间、城市内部和城市之间、产业集群内部和产业集群之间发生的复杂的产业竞合与空间竞合作用，推动着城市群一开发区一产业集群协同发展水平的提高，并促进城市群综合实力和区际竞争力的增强。
