Inter-provincial regional cooperation in China: a case study of Pan-Pearl River Delta cooperation

Chen, Yu, 陈宇 January 2011 (has links)
Since the beginning of the 21st century, regional development has become one of the most vital economic issues in China. Both central and local governments in the nation have implemented policies to reduce regional economic disparities and promote regional integration. On the one hand, the central government has exercised policy and political control to promote regional development. On the other hand, local governments have sought opportunities to foster local economic prosperity by forming more competitive economic blocks with neighboring jurisdictions. In particular, growth poles like the Yangtze River Delta (YRD) and Pearl River Delta (PRD) have been very active in promoting regional integration and cooperation as they need the support of other hinterlands for further development. Literature review indicates that regional cooperation in China is subjected to the influence of both economic and political factors. Although it seems that there is interaction between such economic and political factors. However, there is a general lack of a comprehensive framework to examine regional cooperation in China from a political and economic dynamic perspective. In order to fill the gap, two game theory models are developed to analyze economic and political incentives for government officials in the context of regional cooperation. The first model attempts to determine the important economic factors that may affect the feasibility of a cooperative project, assuming local government officials are maximizing the absolute economic performance of their jurisdictions. The second model focuses on understanding how the political relationship between provincial leaders may affect regional cooperation between them, assuming local government officials are maximizing the relative economic performance of their jurisdictions. A game theory framework to examine the economic political dynamics of regional in China is developed based on these two models. The game theory analysis reveals that incentives for provincial government leaders to implement cooperation are decided by the consideration of their political career, which is driven by three major forces: central-local government relationship, inter-local government relationship and the potential economic benefit from regional cooperation. Pan-Pearl River Delta (Pan-PRD) Cooperation, a typical inter-provincial cooperative project established in the 21st century, is used as a case study to theory framework. The empirical study indicates that the emergence of Pan-PRD Cooperation benefited from three perspectives: (1) policy support from the central government, (2) uneven political relationship between provincial leaders in Guangdong and other eight provinces, and (3) strengthened economic interaction between Guangdong and other eight provinces. / published_or_final_version / Urban Planning and Design / Doctoral / Doctor of Philosophy

Urban competitiveness and regional city-to-city cooperation in the Yangtze River Delta Region : a case study of joint development zones

Xian, Shi, 线实 January 2012 (has links)
With the rise of cities as geographical units, there have been a growing number of municipal partnerships and networks. Government-led intercity cooperation at regional scale—regional city-to-city (C2C) cooperation booms in the Yangtze River Delta (YRD) region in the last two decades. Urban competitiveness is a concept tied to intercity competition that decides the relative position of cities in urban ranking. In regional C2C cooperation, urban competitiveness serves as the asset of partner-cities and usually as one of the primary targets of the cooperation. However, there is a general lack of studies on the influence of urban competitiveness on regional C2C cooperation. The introduction of the perspective of urban competitiveness is an approach of developing a comprehensive framework connecting factors of regional C2C cooperation. The objective of this research is to analyze the influence of urban competitiveness on regional C2C cooperation in China’s local context. In this study, the added value of regional C2C cooperation is divided into added value of urban competitiveness and political added value brought by intervention from upper-level governments. Three typology of C2C cooperation (i.e. hybrid, hierarchical and spontaneous) have been identified. Three cases in the YRD region including the Jiangyin-Jingjiang Industrial Park of Jiangsu Province, Suzhou-Suqian Industrial Park, and Shanghai Caohejing Hi-Tech Park Haining Sub-park are selected for case studies accordingly. This study indicates that urban competitiveness and government intervention are crucial to regional C2C cooperation. Urban competitiveness is essential in regional C2C partnership maintenance, while intervention from upper-level governments is effective and efficient in strategy formulation and partner selection. The measurement of urban competitiveness in the YRD region in 2002, 2005, and 2008 indicates the partner-city with relatively larger urban competitiveness is more likely to assume a leading role in the C2C partnership. Noticeably, it is found that the intervention from the provincial government tends to consolidate such impact. The measurement also reveals that urban competitiveness in the YRD region is transforming from an investment-driven stage to an innovation- and human capital-driven stage. Noticeably, the increasing weighting of basic factors in the building of urban competitiveness found in the YRD region is hard to be explained by the mainstream urban competitive advantage theories. Therefore, a localization of the theories is advocated by this research. Imprints of China’s local context transpire in the three cases, including economic decentralization and simultaneous political centralization. The role of provincial government is weakened in China’s political restructuring. However, revealed by the case studies, intervention from provincial government to regional C2C cooperation is still observed to be effective in terms of strategy formulation and negotiation. With the rise of public-private partnership focusing on investment and economic growth, as well as strong government intervention in regional C2C cooperation, the three cases reflect China’s urban entrepreneurialism. Furthermore, a recent shift in China’s urban entrepreneurialism has been found in the region, which is the increasing emphasis on environmental care for sustainable development. This recent shift accords with the global movement toward environmentalism for sustainable development. The underlying logic and reasons are different from those in the West, resting upon the different nature of involvement and governing process. The findings of this research contribute to a better understanding of the relations between urban competitiveness and regional C2C cooperation in China’s local context and the role of governments. As one of the most developed regions in China, the experiences in the YRD region can shed light on the development of other developing areas. / published_or_final_version / Urban Planning and Design / Doctoral / Doctor of Philosophy

Collaborative environmental management in the Pearl River Delta : an urban operation research approach for electricity consumption

Zhang, Yingxuan, 張映璇 January 2014 (has links)
Electricity generation is the major emission source of air pollutants in the highly industrialized Pearl River Delta Region. In a compact region like the Pearl River Delta, pollutants can easily transfer from one city to another. The research question of this study is to construct an optimal and mutual agreeable scheme to reduce electricity consumption in the Pearl River Delta Region, which involves the collaboration of all cities in the Region. The main objective of the study is to conduct a cooperative scheme that internalizes the external social cost of electricity consumption through optimal electricity consumption reduction. This research first surveys papers on urban environmental problems, especially environmental problems caused in Pearl River Delta Region. Literature review indicates that public electricity generation is the major emission source of air pollutants in this region. Secondly, this research reviews literatures on the social costs of electricity consumption. Reviews show that external costs of electricity consumption in different countries differ widely, ranging from 13% to 700% of electricity price. This study adopts the lower quartile of this range, which is 13% of electricity price. Thirdly, urban operations research is reviewed, and a major policy instrument for environmental improvement, environmental tax, is investigated. This study develops a hierarchical structure of urban operations research to study the collaborative management of electricity consumption reduction in the Pearl River Delta Region. This urban operations research model includes seven essential steps: problem definition; objectives identification; performance measures; data analysis; analytical framework construction; model solution and courses of actions; and policy implementation. Moreover, this novel urban operations research model is applied in collaborative management of electricity consumption reduction in the Pearl River Delta. This research uses statistical and mathematical methods to estimate the parameters relevant to GDP, electricity consumption, external costs of electricity consumption, and environmental tax, and then formulates the operational model. Then, this model is employed to evaluate non-cooperative equilibrium condition among the eleven Pearl River Delta cities under a non-cooperative market outcome; to derive individual city’s external cost of electricity; to derive environmental levy and optimal electricity consumption reduction; and to design a compensation plan. In the compensation plan, under cooperation, in both 2013 and 2014, four cities (Guangzhou, Shenzhen, Foshan, and Dongguan) have to pay for their net spillover external cost of electricity consumption. The other seven cities (Zhuhai, Jiangmen, Huizhou, Zhaoqing, Hong Kong, Macao, and Zhongshan) would receive compensation. The urban operations research model for regional cooperation in electricity consumption reduction developed in this study provides an instrument to deal with the pollution problem in the Pearl River Delta Region. It facilitates the exploration of hitherto intractable problems in regional environmental cooperation and established solution plans. The urban operations model is expected to provide practical policy choices for a Pearl River Delta environmental collaboration scheme. This research represents the first attempt on an application of urban operations research model of collaborative management scheme of electricity consumption reduction in Pearl River Delta Region. / published_or_final_version / Urban Planning and Design / Doctoral / Doctor of Philosophy

Sand distribution along shelf-edge deltaic systems : a case study from eastern offshore Trinidad

Davila-Chacon, Anmar Carolina 15 February 2011 (has links)
The study area is situated along the obliquely converging boundary of the Caribbean and South American plates offshore eastern offshore Trinidad. Major structural elements in the shelf break and deep-water slope regions include normal and counter-normal faults to the south and large transpressional fault zones to the north. Well logs and biostratigraphic information were analyzed for twenty-four wells in the study area to refine previous depositional environment interpretations. For purposes of this net sand distribution analysis it was decided to consider the deltaic portion of the shelf transit cycle, against the marine portion of the shelf transit cycle and were named T and R cycles, respectively. T and R cycles were interpreted based on well log patterns and depositional facies shifts. Six T/R cycles were interpreted within the Pliocene to recent stratigraphic succession and shelf edge trajectories were also mapped for each of these cycles based on earlier stratigraphic correlations. Net-to-gross (NTG) ratios were calculated for each component of the T/R cycles and plotted against total thicknesses and net sand values. In addition, NTG trends were mapped for each interval and analyzed based on their proximity to the corresponding shelf edge. Mapping of the shelf edge trajectories (SET) revealed that (1) SET migrate northeasterly across the Columbus Basin through time and (2) shelf edge orientations are parallel to the strike of growth faults in the south but deflect to the northeast near the Darien Ridge indicating a strong underlying structural control. The NTG plots and maps also revealed that (1) For T cycles, NTG values never exceed 60% and are inversely proportional to total thickness, (2) For R cycles, NTG values are highly variably ranging from 35% to 90%, (3) NTG values increase as the shelf break is approached and (4) The distribution of NTG ratios is also controlled by accommodation space created by local structures. The Guiana current is believed to play an important role in the redistribution and reworking of sand in the Columbus Basin. Aggradation and progradation distances were computed for each interval and the results suggest that the younger Sequences C2 (T-R cycle E) and C3 (T-R cycle F) show a stronger progradational trend than the older C4, C5 and C6. This strong progradational trend might indicate delivery of sand basinwards, while for the older intervals; the aggradational trend suggests an increase in sediment storage. In long-term scale (1-2 m.y.) the Orinoco Delta seems to behave as an aggradational delta that increases sediment storage due to growth fault and high subsidence rates. However, in the short-term scale, the Orinoco delta seems to behave as a rapid progradational delta, for the younger sequences C2 and C3, where sediment bypass is more likely to occur; and as a rapid aggradational (slow prograding) margin for the older intervals C4, C5 and C6. / text

Wetland conservation in British Columbia: the role of environmental non-government organizations in Burns Bog

Delesalle, Bruno P. 11 1900 (has links)
This thesis examines the role of environmental non-government organizations in relation to the role and responsibility of government for wetland conservation in British Columbia. The role of a small community-based environmental organization called the Burns Bog Conservation Society in decisions about Burns Bog, a large privately-owned wetland located in the Lower Mainland, is analyzed. Drawing from a broad range of literature on environmentalism and conservation, the thesis begins with an historical account of the environmental movement, giving a broad view of environmental conservation and the role of environmental organizations. A typology of roles and analytical framework is subsequently derived from a study of environmental non-government organizations involved in managing water resources in British Columbia's Fraser River Basin. Three main roles, advocacy, supplemental and transformative, are discussed as they relate to activities prior to and during the Burns Bog Analysis, a provincially established land use study of Burns Bog. This research found that a small community-based environmental organization, through advocacy, can ensure that ecological integrity is not neglected as a result of poor planning and decision-making. The case study demonstrates that a small environmental organization can pressure governments to broaden their view of land-use and environmental issues, assuring more informed decision-making. An environmental organization can also supplement the regular roles and responsibilities of government, first by supplying a service that government is unable or unwilling to provide, and second by participating in and legitimizing consensus-based decision-making processes. The case study demonstrates how a small environmental organization can provide and review information and participate in creating options and solutions in land-use decisions. Finally, an environmental organization can influence, overtime, the fundamental restructuring of government planning and decision-making processes and transform the way society thinks and operates. The thesis concludes that environmental non-government organizations have an important role to play in ensuring the recognition and conservation of British Columbia's wetlands in government planning and decision-making processes; in informing and educating government and the public about ecological systems and their values; and in counter-balancing strong economic, political and development interests.

Restless landscapes: spatial economic restructuring in China’s lower Yangzi delta

Marton, Andrew Mark 11 1900 (has links)
The development of market socialism in China has contributed to a spatial economic transformation characterized, among other things, by the apparent capacity to rapidly industrialize without transferring large numbers of people into big cities. The most striking element of this transformation has been the phenomenal growth and spatial proliferation of industries in particular areas of the Chinese countryside. The conventional wisdom of existing theories of development, industrialization, and urbanization does not adequately explain the emergence of these relatively productive regions. This thesis examines the key patterns and underlying processes and mechanisms which must be accommodated in a new analytical and conceptual framework for understanding rural transformation and the wider spatial economic restructuring in China's lower Yangzi delta. The overall objective is to explore the theoretical implications of the local character of regional change through an evaluation of a hypothetical model of mega-urbanization. The model situates the emergence and specific patterns of industrial production within a complex network of interactions and interrelationships embedded in overlapping administrative and institutional structures which are themselves largely tied to the circumstances of particular places. The resulting investigations are based upon an analysis of regional and local level statistical and other documentary sources, numerous interviews, field observations, and a survey questionnaire of rural enterprises which was part of a detailed case study of one county level area in the lower Yangzi delta. Two central findings are revealed. First, the patterns and underlying processes and mechanisms of regional development in the delta are fundamentally linked to intensely localized exigencies and opportunities within the wider Chinese space economy. Second, external economies, the dynamics of agglomeration, and the role of large cities and other exogenous forces, while significant, were less important in the delta than were endogenous forces. The details of these findings are incorporated into a revised model of mega-urbanization which highlights the critical processes and mechanisms which underlie the patterns observed, what establishes these processes and mechanisms, and what stabilizes and reproduces them. The thesis concludes by suggesting an agenda for the creation of appropriate planning and management responses for the lower Yangzi delta region.
