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.

The Impact of the Establishment of National High-tech Zones on Total Factor Productivity of Chinese Enterprises

The National High-tech Zone(NHTZs)is an important strategic platform for cultivating high-tech industries and realizing high-quality economic development in China.Based on the combined data from 2006 to 2014 of the industrial enterprise database,the customs database,and the China Development Zones Audit and Announcement Catalogue(abbreviated asthe Catalogue),this paper systematically investigates the influence of the construction of NHTZs on enterprise’s total factor productivity(TFP).Results show that NHTZs have a positive impact on the TFP of enterprises in the zone,and this conclusion is still valid after considering endogeneity problems.Furthermore,the above productivity effects of NHTZs are heterogeneous in terms of enterprise ownership,external environment and establishment time,and NHTZs have greater stimulation effects on enterprise productivity after comparing with other types of functional zones.An investigation of the specific mechanisms at play shows that NHTZs promote the TFP of enterprises in the zone through the release of preferential policies,strengthening the“technology spillover effects”of imported intermediate goods,enhancing enterprise’s innovation ability and attracting talent.In addition,based on the decomposition of industry productivity,this paper also investigates the impact of NHTZs on changes in industry productivity and finds that NHTZs promote the overall productivity of specific industries mainly by stimulating the productivity improvement of incumbent enterprises and expanding the market share of high-productivity enterprises.Moreover,the preferential policies of NHTZs do not significantly stimulate high-productivity enterprises to enter the zones,nor do they cause low-productivity enterprises to exit.This research is helpful in objectively evaluating the economic effects of the NHTZs in China and in providing a theoretical basis for its further adjustment.

国家自主创新示范区设立与服务贸易高质量发展

自主创新是实现企业高质量发展、提升国际竞争力的必由之路。基于1997—2021年中国省级数据,使用合成控制法和双重差分法实证分析了国家自主创新示范区设立对服务贸易高质量发展的影响及其机制。研究发现,国家自主创新示范区设立能显著促进服务贸易高质量发展,且通过技术创新和产业结构升级促进了服务贸易高质量发展。异质性分析发现,相较于中西部地区,国家自主创新示范区设立对服务贸易高质量发展的促进作用在东部地区更大。因此,中国应继续鼓励国家自主创新示范区扩围发展,加快科技成果转化,中西部地区要大力发展科技服务业,以促进服务贸易高质量发展。

综合保税区改善城市企业绿色技术创新效应实证研究

综合保税区在以其扩大对外开放政策平台功能推动经济外向型转型的同时,改善城市企业绿色技术创新效应。笔者以2005—2021年中国内地地级市及以上城市的面板数据,运用双重差分法实证检验了设立综合保税区与城市企业绿色技术创新效应二者之间的关联。检验结果证实:设立综合保税区促进了所在城市企业绿色技术创新效应的提高;综合保税区的制度示范效应和产业结构升级效应与所在城市企业绿色技术创新效应正相关,综合保税区的FDI技术溢出效应与所在城市企业绿色技术创新效应负相关;综合保税区与城市企业绿色技术创新效应的关联性因设立综合保税区城市的地理位置、行政等级和城市规模等不同而表现出异质性;设立综合保税区对城市企业绿色技术创新效应的影响存在某种程度的负空间外部性。本研究将综合保税区通过整合各类海关特殊监管区所具有的多种功能聚焦于如何影响城市企业绿色技术创新效应上,通过实证检验揭示了设立综合保税区与城市企业绿色技术创新效应之间的影响机制,所得研究结论有助于为国家批准、设立综合保税区以及相关部门制定综合保税区具体政策和城市企业充分利用综合保税区改善绿色技术创新效应提供理论依据。

福建和台湾地区在全球价值链中的分工地位和产业分工态势——基于闽台六大类贸易产业数据的分析

福建充分发挥对台工作的独特优势和良好条件,不断深化闽台经贸交流,闽台产业链成为两岸产业链的重要组成部分。基于闽台六大类贸易产业数据,采用出口技术复杂度、G L指数、GHM指数等分析福建和台湾地区在全球价值链中的分工地位和产业分工态势。研究发现:在化学工业和塑料橡胶两大类产业中,台湾地区的分工地位高于福建,在分工态势方面福建相对领先,前者以产业内贸易为主,后者以产业间贸易为主;在机械电气、光学钟表两大类产业中,台湾地区的分工地位高于福建,在分工态势方面台湾地区基本达到绝对领先的水平,且均以产业内贸易为主;在纺织鞋帽和金属制品两大类产业中,福建的分工地位高于台湾地区,但在分工态势方面台湾地区相对领先,前者以产业间贸易为主,后者以产业内贸易为主。新形势下,福建应以建设两岸融合发展示范区为契机,从推动产业转型升级、构建制度体系、优化发展环境、深度融入共建“一带一路”等方面持续深化闽台产业融合发展。

生态文明先行示范区建设对生态环境质量的影响效应及作用机制研究

如何在保持经济持续增长的同时提高生态环境质量是当下我国迫切需要解决的现实问题。本文基于我国2009-2021年284个地级市的面板数据,将生态文明先行示范区建设视为一项准自然实验,运用DID(Differences-in-Differences)方法探究了生态文明示范区建设对生态环境质量的影响效应及作用机制。研究发现,生态文明先行示范区建设对生态环境质量的提升具有显著的正向效应,其影响效应随着时间的推移呈现出先上升后小幅下降的特征,且在西部地区、资源型城市以及工业发展水平高的城市影响更为显著。进一步分析发现,生态文明先行示范区建设可以通过提升政府环境治理水平、促进工业企业绿色转型、提高公众环境关注度三个渠道提升生态环境质量。因此,应加快推广生态文明先行示范区建设经验,因地制宜实施差异化的生态文明建设,积极探索生态文明建设的多维路径,进一步提升全社会生态环境质量。

区域产业政策的制造业质量提升效应——来自产业转型升级示范区的准自然实验

作为区位导向性政策的有效实施载体之一,区域产业政策是经济新常态下促进制造业高质量发展的重要举措。本文将国家级产业转型升级示范区试点建设视为一次准自然实验,以2010~2019年沪深两市A股制造业上市企业为研究样本,采用双重差分法识别了这一区域产业政策的制造业质量提升效应。研究发现:(1)以企业TFP来衡量制造业质量时,基准回归结果表明政策的实施显著推动了制造业高质量发展,使处理组比控制组提高约8%,此结论在多种识别假定检验和稳健性检验中依然成立;(2)异质性分析发现,这一政策效果在国有企业、成长期企业以及资本密集型和技术密集型行业中更加显著;(3)进一步的机制检验表明,示范区政策主要通过提升企业创新能力、改善资源配置效率渠道推动制造业高质量发展,但是并没有培育起当地产业的比较优势。本文的研究结论为进一步完善示范区建设、改革区域产业政策进而推动制造业高质量发展提供了重要的政策启示和决策参考。

区域高端装备制造产业创新网络结构特征与运行效率——以郑洛新国家自主创新示范区为例

借助社会网络分析法,以郑洛新国家自主创新示范区为例,分析高端装备制造产业创新网络及其结构特征,运用随机前沿分析法分技术研发和成果转化两阶段测算创新网络运行效率。结果表明:(1)郑洛新国家自主创新示范区高端装备制造产业创新网络规模较小、密度较低,整体网络结构松散;核心节点以企业、科研机构、高校为主,产学研联盟初具规模;网络结构中以小范围合作创新为主,尚未形成大范围合作创新。(2)2016—2020年成果转化阶段运行效率始终低于技术研发阶段,两阶段存在严重的脱节现象;网络规模、网络结构洞、网络联结均对两阶段运行产出起到促进作用;网络开放性对技术研发阶段的运行产出产生正向影响,但对成果转化阶段的运行产出产生负向不显著影响。
