This paper provides a systematic framework to determine local delivery centre (LDC) locations and service areas to reduce delivery costs and balance the allocation of parcel delivery loads to promote sustainable LDC development. Based on a case study of a parcel distribution company in Korea, this study proposes two strategies for LDC service area delineation within each terminal service boundary that either minimises the total delivery time or balances the allocation of delivery loads. This research contributes to improving cost efficiency and balancing delivery load allocations in planning LDC locations and service areas that can potentially promote the long-term mutual sustainable development of parcel distribution companies and their local delivery counterparts.  相似文献

上海依托其金融、贸易、航运的中心地位,吸引大量的跨国公司总部进驻。近10来年,上海的总部经济规模迅速扩大,形成几个特大规模的总部经济集聚区,但其总部经济的发展也存在较大的问题,总部集群的要素集聚度低,总部集群的创新水平低,总部集群创新环境较差等问题。建设好上海的总部经济有其重要的现实意义,我们应大力提高总部经济的自主创新能力、促进创新环境的建设、构建创新要素的网络结构等。  相似文献

本文利用1997-2013年中国省际层面的面板数据,借助异质性动态调整模型从动态视角考察了地方财政行为对中国贸易收支调整速度的影响。研究结果显示:(1)平均而言,在地方财政行为的驱动下,中国实际贸易收支向最优水平动态调整的速度约为0045。总体表明,地方财政行为对中国贸易收支的驱动性影响较弱,引致实际贸易收支向最优水平调整的速度也较为缓慢。(2)财政支出分权的强化会制约贸易收支的调整速度,贸易收支调整呈现“相对惰性”。财政收入分权的提高和预算内财政支出的扩张能够加快实际贸易收支向最优贸易收支调整的速度,助力贸易收支实现平滑调整。预算外财政支出和财政收入的变化对调整速度则不会产生显著性影响。(3)贸易收支的调整速度呈现显著的区域异质性。本文的结论表明,现阶段中国要实现贸易收支的平衡调整路径,中央及地方政府必须把握好财政行为与贸易收支的动态联动关系。  相似文献

The present article offers a concise theoretical conceptualization and operational analysis of the contribution of innovation to regional development. The latter concepts are closely related to geographical proximity, knowledge diffusion and filters and clustering. Institutional innovation profiles and regional patterns of innovation are two mutually linked, novel conceptual elements in this article. Next to a theoretical framing, the article employs the regional innovation systems concept as a vehicle to analyse institutional innovation profiles. Our case study addresses three Portuguese regions and their institutions, included in a web-based inventory of innovation agencies which offered the foundation for an extensive database. This data-set was analysed by means of a recently developed principal coordinates analysis followed by a Logistic Biplot approach (leading to a Voronoi mapping) to design a systemic typology of innovation structures where each institution is individually represented. There appears to be a significant difference in the regional innovation patterns resulting from the diverse institutional innovation profiles concerned. These profiles appear to be region specific. Our conclusion highlights the main advantages in the use of the method used for policy-makers and business companies.  相似文献

The spread of free trade agreements (FTAs) in Southeast Asia has ignited a debate about their impact on enterprises including the business costs from the Asian ‘noodle bowl’ effect. This paper undertakes a comparative and firm-level analysis of the determinants of FTA use in Indonesia, Malaysia and the Philippines. The likelihood of firms using important ASEAN+1 FTAs (e.g. the ASEAN-China FTA, the ASEAN-Japan FTA and ASEAN-Korea FTA) is positively associated with acquiring knowledge about FTAs, building technological capabilities, and membership in industrial clusters. Non-use of FTAs is explained by a lack of information about FTAs and the absence of FTAs with major trading partners. Key policy implications are the need to improve business support for FTAs, to conclude FTAs with major trading partners, and to create a database on FTA preference use.  相似文献

The present paper investigates how neighborhood effects are connected to chronic poverty. We examine a large sample of groups of households and find that neighborhood effects are significant in a majority of groups, especially in the poorest groups. People living in poor communities tend to suffer from poverty over time. It is of theoretical and empirical importance to explore how neighborhood effects are interrelated with chronic poverty and the channels through which this occurs. Unlike other econometric analyses, we establish a multilevel econometric model to show that: (i) it is difficult for an individual living in a neighborhood with a high proportion of agricultural labor, low education levels, and poor transport and telecommunication infrastructure to escape from poverty traps; (ii) neighborhood effects dominate in poor communities; and (iii) although poverty is affected by group-level factors, individual factors still play a dominant role in regards to escaping poverty when income surpasses a threshold level Therefore, policy priority should be given to providing social protection and public services, especially in poor rural areas.  相似文献

Carbon emission reduction could be achieved through extensive cooperation between relevant groups such as businesses, governments and consumers. Generally, carbon emissions stem from consumer behaviour. To tackle the increasingly serious energy crisis and climate change in China, it is thus vital to control carbon emissions generated by the country's urban consumers. From a consumption perspective, we utilize a self-organizing feature map model to analyse the spatial differentiation of per capita embedded carbon footprint (ECF) in urban China. We found that the spatial differentiation is significant with the per capita ECF of the east coastal area at a high level and that per capita disposable income is the key factor affecting ECF. Based on these findings, potential business opportunities to develop low-carbon products are discussed.  相似文献

The present paper explores the opportunities for China's regional trade agreement (RTA) initiatives to mitigate its anti‐dumping problems. The paper highlights the severity and discriminatory nature of China's anti‐dumping problems. The high concentration of the share of anti‐dumping actions taken by the top 4 and top 8 anti‐dumping initiators is noted. Our finding of a weak effect of existing RTAs on mitigating China's anti‐dumping problems supports the argument that China could become more active in mitigating anti‐dumping problems through RTA negotiations. An RTA can include a higher level of openness in exchange for an improvement in regional anti‐dumping provisions. Case studies on RTAs involving the EU, the USA and India offer some precedents for offering inducements and modifying regional anti‐dumping provisions. The approaches for China may lie in obtaining market economy status from intensive anti‐dumping initiators at RTA levels and also altering regional anti‐dumping provisions that could be put in place in exchange for some potential concessions.  相似文献
