交通运输对区域经济影响效应的研究进展及展望 总被引:2,自引:0,他引:2
交通运输是国民经济发展的命脉,也是区域经济持续快速发展重要的支撑、服务和保障体系的组成部分。本文从区位条件、区域产业结构、区域空间结构、区域市场、区域发展战略、区域合作等方面分析了目前我国交通运输对区域经济影响效应研究的进展,指出交通运输对区域经济影响效应研究中存在的问题,并在此基础上,探讨了我国该领域未来的研究趋向和发展态势。 相似文献

If a highway investment policy instrument is to alter growth in the manner desired, two criteria must be satisfied: (1) the policy instrument must be implemented, and (2) the implementation must achieve the desired policy goal. A look at three decades of highway policy goals (slowing net population growth, reducing arterial congestion, and fostering city-specific population increases) and policy instruments (zoning and sewer restrictions, gridded networks, and highway facility construction or non-construction) provided insights regarding the extent to which Virginia's growth-oriented highway investment decisions satisfied these two criteria.Crucial to the first criterion is that a policy instrument will not be implemented if it lacks a supporting mechanism. For example, the policy instrument of gridded networks in this study lacked any ordinance, financial incentive, or training to facilitate its implementation. Crucial to the second criterion is that highway investments are not effective for achieving a growth-related policy goal. Development will continue in a region despite efforts to slow it by deleting new roads from master plans or will occur elsewhere despite efforts to target it in a specific area. 相似文献

A transportation network-multiregional CGE model is applied to estimate the synergy effects of a set of highway projects on value added by region and industrial sector. This synergy effect is defined as a difference between the summation of the net GDP increase from the development of each highway sub-link without spatial linkage and the change in GDP resulting from the concurrent development of all links with spatial linkages. Among nine east–west highways in Korea, the East–West 9 highway increases the GDP by 0.3% over the 30-year time period horizon, with 0.016% of the GDP due to the synergy effect. The East–West 9 highway has the largest synergy effect of US$0.164 billion per year on the manufacturing sector of Kwangju Metropolitan Area, resulting in a gain in a regional GRP per capita of US$15.88 per year. Since most synergy effects are generated in less developed regions, highway development can contribute to the reduction in regional disparities. 相似文献

This study examines the relationship between company and ownership characteristics and the disclosure level of compliance with Quoted Companies Alliance (QCA) recommendations on corporate governance in Alternative Investment Market (AIM) companies. We report clear evidence that compliance increases with company size, board size, the proportion of independent non-executive directors, the presence of turnover revenue, and being formerly listed on the Main Market. However, we find that shell and highly geared AIM companies disclose relatively lower levels of corporate governance than recommended under QCA guidelines. Our findings suggest that market regulators should review the potential impact of the quality of corporate governance in these companies on the future vibrancy of AIM. We find no evidence that ownership structure or the type of Nominated Advisor is related to disclosure of compliance with QCA guidelines. Overall, in a lightly regulated environment such as the AIM market, it seems that companies will ultimately pursue a cost–benefit strategy in voluntarily complying with good corporate governance practice. 相似文献
