Analysis and Research on Industrial Land Transfer in Hefei City Economic and Technological Development Zone of Anhui Province

In recent years,with high-speed development of economy and society,and fast propulsion of industrialization and urbanization process in the development zone,average annual land demand in the development zone also quickly enlarges,and the contradiction between high-speed growth of economy and shortage of land resources is apparent increasingly. Meanwhile,to guarantee crop safety and stick to 0. 12 billion hm2of farmland red line as a rigid constraint which could not be exceeded,the supply-demand contradiction of industrial land is more and more prominent. With industrial land scale continues to enlarge,land resources become more and more scarce,but there exists the phenomenon of low-efficiency land use and even idle. For land use characteristics of the development zone,taking Hefei City Economic and Technological Development Zone as an example,the countermeasures of perfecting industrial land transfer mechanism in the development zone are proposed.

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.

Strategies to Promote Sustainable Development of Industrial Parks in Vietnam＇s Northern Key Economic Zone

Industrial Parks （IPs） in the Northern Key Economic Zone of Vietnam （NKEZ） have been making significant contributions to the development of the zone since the first two industrial parks--Noi Bai in Hanoi and Nomura in Hal Phong--were established 15 years ago. So far, there have been 51 IPs in the zone, covering a total area of 13,000 ha. Such IPs play a crucial role in mobilizing capital from domestic and international investors for investments in infrastructure enhancement, trade and production aimed at promoting the economic structure transition. However, besides the above benefits, there are a number of unstable factors preventing further development of the IPs. Thus, the objectives of this study are two-fold. The first is to analyze the unstable factors, and the second is to map out strategies to enhance sustainable development of industrial parks in Vietnam＇s northern key economic zone.

尺度重构视角下经济技术开发区向综合功能新区转型的空间应对——以烟台黄渤海新区为例

鼓励和促进经济技术开发区向综合功能新区转型发展,是经开区空间生产转型的内在需求,也是响应国家对经开区发展定位的重要举措。本文基于尺度重构理论视角,以烟台黄渤海新区为例,总结分析经开区向综合功能新区尺度重构的基本逻辑。研究认为,经开区向综合功能新区转型发展的过程,是一次“尺度上移”的过程,通过赋予更高层级的管理权限,重构区域生产关系、社会关系以及治理关系,形成产业协作有序的功能板块、更高标准的产城格局以及更加扁平化的治理结构。研究发现,烟台黄渤海新区在建设过程中,面临多空间主体及多政策制度并存的治理难题,其空间呈松散发展状态,以及低水平的产城融合特征。据此,文章提出整合港产功能板块、调整产城关系以及实施渐进性治理机制的治理策略,推动新区高质量发展,打造带动区域经济高质量发展的重要增长极。

国家级经济开发区如何促进共同富裕:理论机制和经验证据

本文构建共同富裕的综合评价指标体系,利用2002-2020年268个地级市的面板数据,对各地区历年的共同富裕水平进行测度;在理论分析的基础上,利用双重差分模型探究国家级经济开发区的设立对地区共同富裕水平的影响及其异质性。研究发现:(1)国家级经开区设立能够显著提升区域共同富裕水平,这一结论经过一系列统计检验仍成立;但同时,经开区的设立对区域共同度影响显著而对富裕度影响不显著。(2)异质性检验表明,国家级经开区设立对区域共同富裕影响具有区域和空间尺度异质性。(3)国家级经开区主要通过推动产业结构调整、促进产业结构升级促进共同富裕发展。本文研究不仅拓展了国家级经开区设立的多重效应,也为促进共同富裕发展提供新的切入点,还为国家级经开区的进一步完善提供了决策依据。

Scale,Site Selection and Function of Economic and Technological Development Zones

This article analyses different characteristics of scale,site selection and function of the current economic andtehnological development zones in our country.It further proposes that it is inappropriate for the economic andtechnological development zones to follow the“pattern of the special zones”,but a new pattern of“small scale,unitaryfunction and closeness to old city”should be adopted to fit in with the practical conditions in our country.The scale,landuse structure and the relations between the development zone and the old city are the basic issues in planning forthe development zones.These three essential elements constitute the pattern of planning which determines to a certainextent the success or failure of the development zones.

国家级经济技术开发区发展绩效及时空演变分析

国家级经济技术开发区(简称“经开区”)是我国改革开放的排头兵,历经近40年发展,已成为我国经济发展和落实区域高质量发展战略的重要支撑.本文构建了涵盖经开区整体和个体的绩效评价体系,以资源产出率、污染物排放强度和生态效率指标表征发展绩效,定量分析了经开区发展绩效时序变化和生态效率的空间分异.结果表明:①2007—2017年,经开区新鲜水耗、4种常规污染物(COD、NH_(3)-N、SO_(2)、NOx)排放均与经济发展呈相对脱钩.2017年经开区能源和水资源产出率分别是全国工业能源和水资源产出率的1.2和3.5倍,COD、SO_(2)、NOx排放强度是全国工业排放强度的72%、53%、52%.②经开区绝对经济规模两极分化程度不断缓解,对地区经济影响力整体上升.空间分布上,经开区绝对经济规模大的城市从东部沿海进一步拓展到长江流域的中西部地区.③运用数据包络法分析190家经开区的生态效率并识别出典型的投入冗余和产出不足,为经开区精准施策奠定基础.全国仅10%的经开区生态效率为1,污染物排放、温室气体排放、工业能耗冗余是影响生态效率的主要原因.东部地区经开区生态效率平均值为0.35,大于中部地区(0.28)和西部地区(0.26).研究显示,不同地区经开区GDP差异较大,未来要加强不同地区经开区协作提高内生动力;为进一步提高经开区生态效率,需结合研究识别出影响生态效率的关键因素,开展针对性提质增效工作.在经开区实施能耗、水耗以及碳排放总量和强度的“双控”行动;同时,在稳定末端治理成效基础上着力强化全过程和系统优化,深化源头降碳减污.
