This paper describes environmental impacts of tourism and recreation activities in the world heritage listed rainforests of northeast Australia and presents management strategies for sustainable visitor use of the protected area. Tropical rainforests are characterised by their low resistance and moderate to high resilience to impacts associated with human visitation. Visitor use in the World Heritage Area is mostly associated with walking tracks, camping areas, day use areas and off‐road vehicle use of old forestry roads and tracks. Adverse environmental impacts range from vegetation trampling, soil compaction, water contamination and soil erosion at the local scale through to spread of weeds, feral animals and soil pathogens along extensive networks of old forestry roads and tracks at the regional scale. Concentration of visitor use is the most desirable management strategy for controlling adverse impacts at most World Heritage Area visitor nodes and sites, and includes methods such as site hardening and shielding to contain impacts. For dispersed visitor activities, such as off‐road vehicle driving and long‐distance walking, application of best practice methods by the tourist industry and recreational users such as removal of mud and soils from vehicle tyres and hiking boots before entering pathogen‐free catchments, together with seasonal closure of roads and tracks, are the preferred management strategies. Retention of canopy cover at camping areas and day use areas, as well as along walking tracks and forestry roads is a simple, yet effective, management strategy for reduction of a range of adverse impacts, including dispersal of weeds and feral animals, edge effects, soil erosion and nutrient loss, road kill and linear barrier effects on rainforest fauna.  相似文献

This paper analyzes the role of finance capital in regional economic development. A cost‐benefit approach is invoked in order to estimate the welfare impacts of a regional loan and guarantee program for small firms in Israel. Program‐created employment is treated as a benefit and an employment account that separates net from gross employment, is presented. An estimate of net wage benefits is then derived. This involves adjusting wages across different earnings classes in order to account for the variation in opportunity costs of labor at different levels. The estimation of costs includes the opportunity costs of capital, administration, default, and tax‐raising costs. Results point to substantial regional welfare effects. We stress the need to account for changing regional economic structure in this kind of evaluation framework.  相似文献

Australia's large regional cities and towns display wide variation in how they are adjusting to the socio‐economic transitions occurring in Australia. That variation is exposed using a multi‐variate model analysing performance on a range of socio‐economic variables over the decade 1986 to 1996 for 122 cities and towns with populations of 10 000 and above at the 1996 census. Those places are classified into seven clusters of community performance reflecting opportunity/vulnerability, and their spatial patterns are mapped. The resulting framework is then used to show how the recent geography of the socio‐economic performance of the large regional cities and towns has a distinctive selectivity and contributes to opportunity in some places and the vulnerable performance of others. The influence of that selectivity can be seen in the mismatched geographic patterns evident from an analysis of shares of national population and employment change, investment in non‐residential construction, levels of welfare dependency, and the ratio between household income tax generation and transfer benefits received. The paper uses the insights drawn from that analysis to pose questions suggesting the need to rethink national policy perspectives for addressing change in non‐metropolitan Australia.  相似文献

Industries often promote their interests by arguing that they have a big impact on the rest of the economy. This poses the question of how to measure the importance of an activity. To answer this, the literature often uses (regional) input–output analysis. This paper critically reviews the traditional use of multipliers in such cases. To avoid double–counting impacts and to solve related conceptual problems, the net multiplier concept is introduced. This net multiplier is illustrated empirically for the Dutch transport sector using a Type II biregional input–output model for the Netherlands.  相似文献

Interregional spillovers and the expansion of capacity in hinterland sectors represent two types of economic impact associated with large capital projects in hinterland regions. The simultaneous treatment of these within an input-output (I-O) framework is the subject of this paper. A dynamic multiregional I-O (DMRIO) model is derived and applied to a scenario of oil development in Canada's Northwest Territories (NWT). A comparision of output profiles generated by the DMRIO model and a static MRIO model shows that the DMRIO formulation has merit. Specifically, in years where capacity adjustments are called for in the hinterland region, the static MRIO model is unable to capture the intraregional and interregional economic implications of this activity. In a year of particularly large-capacity shortfalls in several NWT sectors a static MRIO model underestimates the Canada-wide total impact of the project by more than one billion 1984 dollars.  相似文献

A discussion of the use of economic models for the planning of new industrial enterprises or changing the specialization of existing enterprises within industrial complexes. Despite some differences in N. N. Kolosovskiy's definition of a territorial production complex and Walter Isard's definition of an industrial complex, Isard's method of building economic models is found applicable to Soviet conditions.  相似文献

Three Taiwan-based economists evaluate regional economic integration in East Asia, using trade indicators to analyze the degree of trade concentration among East Asian nations, and employing the gravity model to identify key factors influencing bilateral trade flows among them. China is expected to play a key role in East Asia's economic development, and empirical analysis for the period 1990-2005 indicates that East Asia has already evolved into a trading block, expected to become one of three dominant blocks in the global economy. The study, which highlights the key role played by geographical distance and market size, suggests that the impact of the Association of Southeast Asian Nations (ASEAN) for East Asian trade will remain limited in the future.

A variety of approaches used in Soviet economic geography to define and measure the productive specialization of an economic region are reviewed. In the author's view, a regional activity qualifies as regional specialization if it helps shape the basic character of the regional economy. It is not sufficient for a regional activity merely to represent a major portion of a particular national sector of the economy. For example, the asbestos industry in the Urals represents the major portion of Soviet asbestos output, but asbestos does not shape the basic character of the Urals economy and is therefore not a principal specialization sector. Regional specialization derives from relationships among the various sectors of the regional economy, not from the significance of any particular commodity. A classification of economic sectors is proposed as an aid in analyzing the functioning of a regional economy: (1) the principal specialization sectors; (2) basic raw-material sectors; (3) associated sectors using the wastes and by-products of the principal sectors; (4) complementary specialization sectors, such as asbestos in the Urals; (5) auxiliary sectors, such as metallurgical fluxes for the iron and steel industry; (6) service sectors, including utilities, transportation, construction, trade; (7) local sectors, working for local consumption.  相似文献

The author holds that regional geography cannot be regarded as an independent geographic discipline because it lacks its own system of laws, such as the natural laws that operate in physical geography and the social laws that operate in economic geography. He agrees with the view that both physical and economic geography fall into theoretical and regional departments, and that regional studies test the localized application of the general laws formulated by the theoretical departments of the two great divisions of geography.  相似文献

去工业化:旅游发展对桂林工业部门的影响研究   总被引:2,自引:0,他引:2  
旅游发展对目的地工业部门的影响迄今为止尚处于争议之中.本文运用VAR协整分析、格兰杰因果检验、脉冲响应函数和方差分解等动态经济计量分析方法对桂林市旅游发展与工业增加值比重变化之间的关系进行了实证研究.研究结果表明,在经济不受任何干预的条件下,旅游业的扩张将挤出目的地工业投资资本,转移工业劳动力而造成工业增长水平的下降,给目的地带来去工业化效应;但旅游发展带来的价格效应不明显.旅游目的地可以通过制定产业政策对生产要素的流动方向进行控制,以有效地避免旅游发展带来的去工业化问题.  相似文献

A close reading of a neoliberal intervention in policy debates on ‘the regional economic problem’ is used to throw light on this method. When it is compared to economic geography, the neoliberal approach advances a relatively simplified conception of regional economic and social life that pays little regard to their richness, complexity and grounded realities. Correspondingly, this approach encourages a vision of regional policy that normalises and exonerates the spatially uneven outcomes of market forces. This article argues that policy‐makers’ ends in the field of regional development should be alert to the limitations that arise from the neoliberal tendency to override the evidence of empirical complexity in favour of a more simple narrative.  相似文献
