战后60年代第一次农业革命(绿色革命)的兴起·显著地推动了世界经济的发展。近年来,生物技术革命的风起云涌,又引起一场新农业革命(白色革命)的悄然兴起。新农业革命(基于白色农业)必将导致农业结构从自然型向人工型转换,从而在21世纪内将实现现代农业转向“未来大农业”的结构重组。21世纪必将是农业的新世纪。 相似文献

通过介绍GDP指标及其对我国经济发展的影响,分析了它与产能过剩之间的关系,提出应引入绿色GDP评价指标。认为将绿色GDP指标作为衡量我国政府绩效的指标,既符合绩效审计寻求发展的内在要求,又是实现可持续发展的必然选择。因此,在今后的经济建设中,各级政府应努力贯彻"科学发展观",建立纳入了资源耗减成本与环境成本的“绿色GDP”评价指标,形成可持续发展理念。 相似文献

How psychological and contextual factors contribute to travelers’ propensity to choose green hotels?
Despite the growing popularity of green hotels, there remains a dearth of research examining travelers’ intentions to choose green hotels. The study addresses this research gap by developing and testing an integrated model of green hotel behavior in an emerging market of India. We use a sequential approach of SEM and fuzzy set qualitative comparative analysis on 347 responses collected from Indian travelers to gain a more in-depth understanding of the role of biospheric value, green trust, willingness to pay premium, attitude, subjective norms, and perceived behavioral control in determining green hotel intentions. The findings show that presence of green trust is a significant and necessary condition for green hotel choice. Additionally, absence of willingness to pay premium, biospheric value, attitude, and subjective norm were found to deter travelers from choosing green hotels. These findings offer unique insights for managers in developing marketing strategies to enhance travelers’ green hotel adoption. 相似文献

Consumers’ buying behavior is not always consistent with their positive attitude, particularly toward environmentally friendly products. In a survey of 197 travelers, the relative importance consumers ascribe to the attribute of green was assessed. Through a multi-methods study involving interviews, focus groups discussions, and forced-choice experiments that simulate market buying situation, it was found that consumers’ selection of hotel rooms is still much dictated by traditional choice factors. Through a conjoint analysis, it was found that consumers highly prioritized the price attribute. The green attribute was assigned a low relative importance of 4% among the respondents. Managerial and theoretical implications are discussed. 相似文献

We quantify the impact of jointly optimizing strategic network design and tactical inventory planning on the cost and CO2 emissions of multi-echelon logistics networks. The obtained insights indicate that longer optimized replenishment cycles reduce a node’s transportation cost and CO2 emissions but increase its inventory costs. Moreover, under a fixed replenishment cycle, a node’s service level increases when supplied by a satellite warehouse. Finally: (i) the costs of implementing optimal green network design decisions could be misleading if inventory planning is neglected, (ii) greening of supply chains could become expensive, (iii) current legislative CO2 ton prices hardly influence logistics networks. 相似文献

We introduce a new numerical method called the complex Fourier series (CFS) method proposed by Chan (2017) to price options with an early-exercise feature—American, Bermudan and discretely monitored barrier options—under exponential Lévy asset dynamics. This new method allows us to quickly and accurately compute the values of early-exercise options and their Greeks. We also provide an error analysis to demonstrate that, in many cases, we can achieve an exponential convergence rate in the pricing method as long as we choose the correct truncated computational interval. Our numerical analysis indicates that the CFS method is computationally more comparable or favourable than the methods currently available. Finally, the superiority of the CFS method is illustrated with real financial data by considering Standard & Poor’s depositary receipts (SPDR) exchange-traded fund (ETF) on the S&P 500® index options, which are American options traded from November 2017 to February 2018 and from 30 January 2019 to 21 June 2019. 相似文献

Nowadays, interest in corporate environmental strategies shifts from cleaner processes to the holistic nature of green products. The relevant literature argues that firms have the opportunity to pioneer through green product innovation, allowing them to differentiate and thus gain competitive advantage. Environmental burden of products during their entire life cycle is undeniable. Due to the weakness of the existing literature that inadequately addresses a commonly accepted green product definition, as well as the thereby caused inconclusive academic empirical results on firms' competitiveness, there are many cases of businesses greenwashing behavior. The overall contribution of this exploratory paper, on determining and evaluating the degree of greenness of a product, is twofold; first, starting with a systematic literature review, authors further contribute by proposing an integrative definition that addresses the so far existing terminological gap. Next, after reviewing the existing environmental assessment tools, authors based on the developed definition and in accordance to its dynamic dimension contribute to the existing methodology, as the paper reveals issues that need to be considered in the evaluation of green products. 相似文献

This study examines the time-frequency co-movement and network connectedness between green bonds and other financial assets in China. We propose wavelet coherence and multiscale TVP-VAR to explore the time-frequency co-movement and spillover connectedness. The empirical results are as follows. First, green bonds positively co-move with conventional bonds across time scales and negatively co-move with stocks and commodities. Second, there is a significant network connectedness of green bonds with conventional bonds in the short term, and the connectedness with stocks and commodities gradually strengthens with the increase in time scales. Third, the dynamic spillover between green bonds and other assets is much greater in the long and medium terms than in the short term. Finally, under crisis shocks, the spillovers spike temporarily in the short term, while they are persistent and at a high level in the long term. Overall, some practical implications are proposed for investors and policymakers. 相似文献
