The spatial division of industries of the pearl river delta in the 1990s: Characteristics and trends

The article analyzed the spatial division of industries of the Pearl River Delta (PRD) in the 1990s, a period that witnessed the deepening of the reform and opening policies and continued rapid development of the region. By adopting the index of specialization, the extent of specialization, its change and its spatial distribution in the region are measured and demonstrated. The research revealed that, despite the trend of more balanced development of the secondary sector between the PRD and the rest of the province, in the PRD, it is the unbalanced development that dominated and the spatial division of the secondary sector has been shaped. The tertiary industry has also been experiencing unbalance development and the spatial division of the tertiary sector has been emerging, its extent of concentration appearing even more evident than that of the secondary sector. The author also discussed the linkage between the spatial division of the two sectors. In the end of the paper, the trends of the spatial division of the industries in the PRD are forecasted.

THE REGIONAL DEVELOPMENT IN THE PEARL RIVER DELTA IN NEW TERM

Since China opening to outside world, the economy in the Pearl(Zhujiang) River Delta(PRD) has been dou-ble digit growth. It has been known as one of mature fast growth areas in the world and become the model and hope of Chi-nese reform and opening to outside world. The regional development in PRD is the outcome of polarization effects. The polar-ization effects actually are extension of international regional division and a combination of Hongkong‘‘s influence and re-form and open-door policies on the mainland. Since the 1990s, driven by knowledge-based economy, the PRD has furtheradjusted the industrial structure and achieved good progress in upgrading industrial structure. Its high technology industryhas developed quickly and the economic internationalization has deepened, meanwhile, the region is going through transforma-tion and some new trends have begun to appear, which include: university towns springing up, industrial globalization andthe construction of Hi-tech development zones. The paper suggests that with the economic growth changing from relying onthe low level production elements to relying on high level production elements, the regional policies in GuangdongProvince should develop correspondingly: 1) make a plan to prohihite the blind construction in innovative spatial construc-tions; 2) make measures to attract the overseas talents to establish a pool of talent; 3) work out the favorable policies forabsorbing larger capital; 4) formulate the policy of attracting a cluster of industries to speed up the upgrade of industrialdevelopment.     

闽南金三角地区经济增长与产业重心的时空演变

闽南金三角地区已成为中国东南沿海重要的经济增长高地。然而,在同城化背景下,该地区的城市空间重组、区域协调等问题凸显,严重制约了区域可持续发展。本文运用重心模型揭示了2000-2012年闽南金三角经济增长以及三次产业重心迁移的时空演变特征与规律,并用Nich指数进一步分析三次产业差异。结果表明:(1)闽南金三角地区极化发展现象突出,2000年以来地区经济增长重心与二、三产业重心高度集聚于厦门市东北部,且东西向极化现象较明显;(2)厦、泉两地经济增长博弈激烈,2008年后第三产业开始回迁,且其对经济增长有一定的牵引效应,地区间第二产业非均衡性发展有所收敛;(3)第一产业重心往西南地区迁移的直线型态势显著,漳州市二、三产业发展均滞后于厦、泉地区。     

ON THE OPENING-UP AND DEVELOPMENT OF SHANGHAIS PUDONG NEW AREA

In the development of Pudong, a strategic idea and goal ought to be fully realized, that is: with the development of Pudong as a lead, to further open up the cities along the Chang jiang (Yangtze) River, build Shanghai into an international center for economy, finance and trade, thus to spark a new economic take-off in the Changjiang River Delta and the whole Changjiang River Basin.To develop Pudong, the infrastructure construction must be developed first; and the development of primary, secondary and tertiary industries must be well coordinated. At present, the stress should be laid on tertiary sectors like finance, foreign trade, commerce, real estate, far-ocean transport, post and telecommunication, information and travelling service and so on. In the secondary industry, export processing and high and new technological industries should be put first, while the original raw-material industry should be improved in processing depth. As to the primary industry, a metropolitan suburban agriculture should     

Relationship Between Producer Services Developing Level and Urban Hierarchy —— A Case Study of Zhujiang River Delta

As the Central Place Theory indicates, the centricity of a central city can influence the extension of its service. Since the service industry in the theory is mostly consumer services, it is worth studying the relationship between the producer services and the centricity of the city in the service society with producer services becoming a more important part of the service industry. The paper takes the case of the Zhujiang （Pearl） River Delta （PRD）, a developed region in China, to study the relationship between the developing level of producer services and the urban hierarchy. Based on the analysis about the spatial difference of the producer services in the nine cities of the PRD, and the division of the nine cities according to some economic indices, it is shown that there is a correlation between the developing level of producer services and the urban hierarchy. Furthermore, two deductions about the future status of the producer services in the city and the location of the producer services in a large region can be made from this correlation between the developing level of producer services and the urban hierarchy.

Impact of the Built Environment on the Spatial Heterogeneity of Regional Innovation Productivity: Evidence from the Pearl River Delta,China

With the global economy increasingly dependent on innovation, urban discourse has shifted to consider what kinds of spatial designs may best nurture innovation. We examined the relationship between the built environment and the spatial heterogeneity of regional innovation productivity(RIP) using the example of China's Pearl River Delta(PRD). Based on a spatial database of 522 546 patent data from 2017, this study proposed an innovation-based built environment framework with the following five aspects: healthy environment, daily interaction, mixed land use, commuting convenience, and technology atmosphere. Combining negative binomial regression and Geodetector to examine the impact of the built environment on RIP, the results show that the spatial distribution of innovation productivity in the PRD region is extremely uneven. The negative binomial regression results show that the built environment has a significant impact on the spatial differentiation of RIP, and, specifically, that healthy environment, mixed land use, commuting convenience, and technology atmosphere all demonstrate significant positive impacts. Meanwhile, the Geodetector results show that the built environment factor impacts the spatial heterogeneity of RIP to varying degrees, with technology atmosphere demonstrating the greatest impact intensity. We conclude that as regional development discourse shifts focus to the knowledge and innovation economy, the innovation-oriented design and updating of built environments will become extremely important to policymakers.     

FLUS-UGB多情景模拟的珠江三角洲城市增长边界划定

城市增长边界（UGBs）能够控制城市空间的无序蔓延并引导城市合理增长,多发展情景下的UGBs是对不同规划条件下城市未来发展空间范围进行界定的常用方法。元胞自动机（CA）模型能对未来城市发展进行动态的预测,并已广泛的应用于UGBs的划定中。然而,目前的方法和模型大多只针对单一的城市发展情景进行UGBs的划定,较少能对未来多种发展情景下的UGBs进行准确划定。因此,针对这个问题本文提出了一种基于未来用地模拟（FLUS）模型和膨胀与腐蚀的算法的多情景UGBs划定模型（FLUS-UGB）。本文选取珠江三角洲地区为研究区,在对2000-2013年珠江三角洲地区城市土地利用进行模拟和验证的基础上（Kappa系数为0.715,总体精度为94.539%）,预测了2013-2050年基准、耕地保护及生态控制3种情景下珠江三角洲地区的城市扩张,并根据预测结果对该地区UGBs进行划定。结果显示,该方法能够针对不同的城市发展情景进行相应UGBs的划定,具有较好的可靠性及适用性。

A new perspective on China’s industrial development strategy

At present China is facing challenges from economic globalization, ecological economy and knowledge economy in its process of economic development. The following ideas may be heuristic in establishing China’s regional development strategies: 1) In locating industries, the impact of industries on the eco-environment should be fully considered. 2) Industrial restructuring should be focused on the restructuring of products, not on the restructuring of the three traditional industries (primary, secondary and tertiary industries). 3) The establishment of key industries should be focused on large-scale corporations or famous brand products, not on a particular industrial sector. 4) The complementarity and cooperation between the east and the west of China should be on products and markets, not on natural resources. The advantages in natural resources for the west of China can not be over-estimated. The advantages in products and market potentials for the west of China may be explored.

Spatial agglomeration of exhibition enterprises on a regional scale in China

During the past two decades, the exhibition industry in China has been developing rapidly and has become an important part of the modern service industry, particularly the agglomeration characteristics of exhibition enterprises highlighted on the regional scale. Although the development of theoretical research on the western exhibition industry has taken place over time, the spatial perspective has not been at the centre of attention so far. This paper aims to fill this gap and report on the agglomeration characteristics of exhibition enterprises and their influential factors. Based on data about exhibition enterprises in the Pearl River Delta(PRD) during 1991–2013, using the Ripley K function analysis and kernel density estimation, this research identifies that: 1) the exhibition enterprise on the regional scale is significantly characterized by spatial agglomeration, and the agglomeration density and scale are continuously increasing; 2) the spatial pattern of agglomeration has developed from a single-center to multi-center form. Meanwhile, this paper profiles the factors influencing the spatial agglomeration of exhibition enterprises by selecting the panel data of nine cities in the PRD in 1999, 2002, 2006 and 2013. The results show that market capacity, urban informatization level and exhibition venues significantly influence the location choice of exhibition enterprises. Among them, the market capacity is a variable that exerts a far greater impact than other factors do.
