The mining industry is an important sector of the national economy, which provides essential support for energy and other resources for economic development. Industrial linkage and economic distance are two different concepts in measuring the correlationship of different industries, in this article, we apply the model that combines both of them to analyse the industries significantly influence the mining industry. We find that electricity and heating industry, and the mining industry itself from forward linkages have greatly influenced the mining industry, and the industries from backward linkages affect mining industry are changing with industrial economic transformation. We also find resources can flow across several regions only after 2007, which means the role of geographical factors limiting long-range transportation of resources is weakening after 2007. And we explain how resources flow among various regions during 1997 ~ 2007. Based on the findings above, policy implications from the empirical results obtained are discussed. 相似文献

In the Ming and Qing Dynasties (1368–1911), China saw rapid development in industrial and commercial sectors. Over this period, a group of merchants originating from the inland province of Shanxi gradually built a multilevel financial system and became leaders in China’s banking sector. The system of financial institutions they established (pawnshops, seal shops, money shops, loan banks, and draft banks) each had a unique business model, with specific target client group and carefully designed risk management. They were also interconnected to allow for flexible capital flows, contributing to the fast economic growth in this period. Nevertheless, the traditional system also had limitations, leading to its replacement by modern banks eventually. 相似文献

The 1992 Earth Summit and its message of sustainable development drove the launching of a System for integrated Environmental and Economic Accounting, the SEEA. Since then, sustainable development and the SEEA have given way to green growth and green economy indicators in the latest 2012 Summit. A lengthy revision process has now produced a curtailed “SEEA central framework.” The new framework focuses on expenditures for environmental protection and resource management, and stocks and flows of “economic” resources; both are covered by the conventional national accounts. Environmental degradation, notably from pollution, is left to “experimental” ecosystem accounts. Further revision of the SEEA should reverse this retrenchment from integrative environmental–economic accounting. A comprehensive satellite system, rather than a limited statistical standard, might put the SEEA back on the policy agenda. 相似文献

Over the past centuries, land systems in Italy experienced fundamental shifts, owing to the availability of new energy forms, population surges, and technological progress. The 20th century was characterized by massive productivity increases, accompanied by gradual land abandonment and the return of forest land. We here analyze 120 years of land system change in Italy, applying the human appropriation of net primary production (HANPP) framework, a metric for socio-economic pressures on terrestrial ecosystems. HANPP allows integrating ecological with societal perspectives, by systematically quantifying (a) biomass harvest and (b) the difference between potential productivity of ecosystems and current productivity induced by land use processes, such as land conversion, or land degradation. Besides assessing national trends we calculated HANPP separately for the Italian North and South between 1934 and 2007, in order to scrutinize if high regional discrepancies in terms of natural and socio-economic preconditions translate into diverging land system trajectories. Our results show that national HANPP has been declining from 78% of natural productivity before WWII to 56% in 2007, indicating a declining land -use induced pressure on biomass flows over time. Simultaneously, biomass harvest increased by around 26% due to agricultural intensification, despite shrinking croplands. Although we found a significant difference between the Northern and Southern region in the absolute levels of several land use indicators related to biomass appropriation, the overarching trends of land system change were remarkably similar in both regions. This suggests that underlying drivers of land system change, such as policies aimed at land-use intensification and structural change were equally dominating land system trajectories in the North and South of Italy, not withstanding their socio-ecological divergences. 相似文献

在日常生活中,任何人都无法离开法律而生活,因为法律是与生活息息相关的。正如西方法律谚语所说:立法者不是创设法律,而是发现法律。生活离不开法律,法律来自于生活。生活里人们无时不刻地在为自己和他人创设权利与设置义务,从而生成各种民事法律关系。但是,权利与义务不会无休无止地存在,当一方信守承诺积极履行自己的义务时,另一方亦不能"躺在权利的床上酣眠"。不论是权利还是义务,都会有消亡的时刻,即一个时间限制,法律中叫做时效。为此,对中国公民哪些权利会受到时效的限制及该受多长时间的限制进行了论述。 相似文献

This research tests the mediational roles of hedonic and utilitarian values consumers receive from using mobile data services (MDS) on the relationship between mobile commerce experience and mobile provider brand equity. A theoretical model was developed based on a review of the existing literature, and a survey was developed to test the model using a sample of 371 students in major universities in Jordan. The structural findings showed that MDS experience positively influence MDS provider image, which positively influenced both utilitarian and hedonic values, the effect being stronger for the utilitarian value. Moreover, both types of perceived values from using the MDS fully mediate the effect of MDS provider image on mobile equity. 相似文献
