Impact of Hinterland Manufacturing on the Development of Container Ports: Evidence from the Pearl River Delta, China

Container ports and hinterland manufacturing are two important forces of the local participation in economic globalization.This study,taking the Pearl River Delta(PRD),China with an export-oriented economy as an example,applies Huff and panel regres-sion models to evaluate the impact of hinterland manufacturing on the development of container ports during the period of 1993–2019.The results show that 1)the spatial patterns of hinterlands for hub ports help to determine the distribution range and scale of economic variables that affect port throughput;2)the hinterland’s gross manufacturing output has universally positive influence on port through-put,wherein export-oriented processing and the entire manufacturing industry have significantly positive impact on port throughput in 1993–2011 and 2001–2019,respectively;3)the two internal structural factors related to an export-oriented economy,labor-intensive sectors and foreign-funded terminals,have positively moderate the direct influence of hinterland manufacturing on port throughput.Our results highlight the importance of local context in understanding port-manufacturing relationship in developing economies.Based on our findings,policy implications are further proposed to enhance port network organization in PRD.

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 reformand opening to outside wo rld.The regional development in PRD is the outcome of polarization effects .The polar-ization effects actually are extension of international regional divis ion and a combination of Hongkong’s i nfluence and re-form and open-door policies on the ma inland.Since the 1990s,driven by knowledge-based economy,the PRD has f urther adjusted the industrial structure a nd achieved good progress in upgradi ng industrial structure.Its high te chnology industry has developed quickly and the econom ic internationalization has deepen ed,meanwhile,the region is going th rough transforma-tion and some new trends have begun to appear,which include:university t owns springing up,industrial globalization and the construction of Hi-tech develop ment zones.The paper suggests that w ith the economic growth changing fro m relying on the low level production elements to relying on high level production ele ments,the regional policies in Guan gdong Province should develop correspondingly:1)make a plan to prohibite the blind con struction in innovative spatial con struc-tions;2)make measures to attract the overseas talents to establish a pool of talen t;3)work out the favorable policies for absorbing larger capital;4)formulate the policy of attracting a cluster of industries to speed up the upgrade of industrial development.

Evidences and implications of vegetation damage from ceramic industrial emission on a rural site in the Pearl River Delta of China

Community structure characteristics and vegetation damage degree were investigated and analyzed in a forest around village, which had been long term exposed to ambient atmospheric pollution stress, to study the influence of airborne pollutant emissions from the concentrated ceramic industries on vegetation. Field survey was carried out in a semi natural secondary forest on hilly land, Nanhai District of Guangdong Province, for the tree layer in ten quadrates with the total area of 10 × （10 m×10 m）, and for shrub and herb layers in eight subquadrates with the total area of 4 × （5 m×5 m）. Results showed that exotic Eucalyptus exserta and Eucalyptus urophylla were dominated over the community, followed by native tree species, Scheffiera octophylla and Bambusa gibba, with the importance value （Iv） of 26.75, 17.08, 16.27 and 11.50, respectively. Among all tree species, Eucalyptus exserta and Pinus massoniana were most severely damaged with nearly 100% damaged rate. Bambusa gibba and Dalbergia balansae were injured with damaged rate of 85.1% 68.3%, however, Eucalyptus urophylla, Celtis sinensis, Helicia cochinchinensis, Cinnamomum burmanni and Vitex negundo revealed moderate injuries （45%-57.5%）. Most of other indigenous species including Schefflera octophylla, Viburnum odoratissimum, Desmos chinensis, etc. showed less injured symptoms under the pollution stress. Compared with species in tree layer, damages of undergrowths were largely less. These results suggested that attention and concern should be paid on those introduced Eucalyptus species which had ever been widely used for forest restora tion in degraded hilly lands of south China since 1970-1980s, due to their last growing aspect, The results also demonstrated the potentials and perspectives by developing native species as target plants for restoration of degraded area at similar polluted location, which may provide scientific base for scientists to study and understand the functional aspects of native species and process-based interactions with pollution stress.

THE SPATIAL DIVISION OF INDUSTRIES OF THE PEARL RIVER DELTA IN THE 1990s: CHARACTERISTICS AND TRENDSS

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.

Local Area Quotas for Industrial Emissions along Reaches of the Pearl River in Guangdong

There is an obvious departure from the regional equi-librium of developments between the upper and lower reaches of the Pearl River in Guangdong, which resulted in "the effects of contra-geography-grads development". It is mainly because the upriver mountainous areas have been deeply stuck in industriali-zation delay and marginalization plights, so that nearly 40 million local people have conceived a dream to get rid of "the vicious circle of poverty" by speeding up industrial development. But the problem is that such industrialization efforts on a large scale in mountainous areas are encountering the bottleneck of environ-mental capacity that strictly limits industrial emissions along the upper reaches of any water system. As a solution, an institutional arrangement called "the Local Area Quotas for Industrial Emis-sions along the Pearl River" is put forward supposed to give cor-responding compensation to the rights of industrial development yielded by some areas with lower environmental capacity through the distribution and trading of IDQs.

The Influence of the Urban-Rural Income Disparity on the Industrial Structure—Taking the Yangtze River Delta Region as an Example

In this paper, the effect of the mediation effect is mainly used to test and analyze the regression model, and most scholars have studied the impact of the modernization of the industrial structure on the income gap. However, this paper is from another perspective, based on the social background of high-quality development, the main study is the impact mechanism of urban and rural income gap on the industrial structure, taking the Yangtze River Delta as the main research object, and specifically selecting 22 central cities in the Yangtze River Delta region, which is also one of the highlights of this study. The regression model is constructed by using the intermediary effect, and the four intermediary variables of fiscal expenditure (M1), fixed asset investment (M2), number of patent applications (M3), and total import and export (M4) are selected, which represent the role of the government, fixed asset investment, scientific and technological level and opening-up level, and study and analyze the inherent influence mechanism between each variable. Before doing specific research, I consulted the papers and literature of many other outstanding scholars, among which Cheng Yuhong and Cheng Chi’s “The Influence Mechanism of industrial structure of urban and rural income gap” [1] has great reference value for this paper. According to the research results, under the background of high-quality development in the Yangtze River Delta region, the expansion of the income gap between urban and rural areas will inhibit the upgrading of the industrial structure, so it is necessary to focus on building a new type of urbanization, accelerating the construction of an urban innovation system, optimizing the rural employment structure to narrow the income gap between urban and rural areas, and providing impetus for the continuous upgrading of the industrial structure.
