At its 19th National Congress, the Communist Party of China vowed to “strengthen the financial sector’s ability to serve the real economy.” However, many studies provide evidence of the opposite trend, a problematic “transition from the real to the virtual,” among Chinese enterprises. Meanwhile, the investment efficiency of China’s Social Security Fund (SSF), a public fund, attracts much attention. In this context, we use A-share listed companies in China from 2009 to 2018 to study the relationship between holding by the SSF and enterprise financialization. We find that SSF holding significantly inhibits financialization and that this effect is non-linear. Mechanism analysis indicates that SSF holding suppresses enterprises’ financialization mainly by improving their governance. Moreover, SSF holding more strongly inhibits small-scale (vs. large-scale), state-owned (vs. non-state-owned), and non-eastern (vs. eastern) enterprises in China. Furthermore, SSF holding can alleviate corporate value impairment caused by financialization. The conclusions enrich theoretical research and provide empirical evidence that may help regulatory authorities to guide investment by enterprises and prevent financial risks. 相似文献

This paper addresses from an economic perspective the issue of global biodiversity conservation. It challenges the perception
that the world really cares a great deal about biodiversity and is prepared to pay the full cost of maintaining this stock
of natural capital. Despite the existence of a plethora of international agreements there still seems to be a global ‘deficit
of care’ surrounding efforts to combat challenges such as those posed by global warming and biodiversity conservation. More
light can be thrown on the degree of care by measuring both the actual expenditures and the stated willingness to pay for
biodiversity conservation. However, actual expenditures are much lower than willingness to pay estimates recorded in the published
literature. Using the criteria that the ‘right’ amount of conservation effort is one where the marginal economic benefits
from conservation just equal the marginal costs of conservation, the paper explores the biodiversity conservation conundrum
and concluded that, on the available evidence, the world does not care too much about this natural capital stock and bequests
to future generations.

Protecting human health is a primary goal of environmental policy and economic evaluation of health can help policy-makers judge the relative worth of alternative actions. Economists use two distinct approaches in normatively evaluating health. Whereas environmental economists use benefit-cost analysis supported by monetary valuation in terms of willingness-to-pay, health economists evaluate interventions based on cost-effectiveness or cost-utility analysis (CEA), using quality-adjusted life-years (QALY) or similar indexes. This paper provides background on the controversy about the relative merits of these approaches and introduces the remaining papers in the special issue. These papers (with one exception) were presented at a conference sponsored by the Department of Economics at the University of Central Florida with support from the US Environmental Protection Agency. Although CEA might not lead to substantially different implications for environmental policy than benefit-cost analysis, and QALY may provide a benefit transfer tool to fill gaps in the morbidity valuation literature, the papers in this issue raise serious concerns about the suitability of QALY-based CEA for environmental regulatory analysis. QALY does not in general appropriately represent individual preferences for health and CEA is neither independent of income distribution nor adequate to assess efficiency. 相似文献

退耕还林(草)生态补偿实施现状与问题分析——以甘肃省定西市安定区为例 总被引:1,自引:0,他引:1
为了建立合理的国家生态补偿机制,了解现阶段生态补偿中存在的问题,我们运用PRA(Participatory rule appraisal)即参与性农村评估和传统的问卷调查相结合的方法,通过对研究区内生态建设补偿措施实施过程中的现状研究、问题分析,发现本区在实施退耕还林(草)生态补偿中的主要问题是仍然没有有效解决生态补偿的三个基本问题:补偿主体、补偿强度、补偿资金来源。生态补偿处于初级阶段,没有形成制度化、法律化,有必要在政策、法律层面建立比较完善的生态补偿机制。 相似文献

In this paper we estimate the willingness topay for a wolf management plan and a wolfdamage plan in Minnesota using the contingentvaluation method. The theoretical definition ofwillingness to pay for wolf protection iscomposed of use and non-use values. Weincorporate a don't know response option in thedichotomous choice valuation questions. A largenumber of respondents answered don't know. Themultinomial logit model is used todifferentiate between don't know and noresponses. Non-use motives are importantfactors that explain willingness to pay. We usethese benefit estimates in combination with twoalternative cost estimates to consider theefficiency of the wolf management and damageplans. Both plans have estimated benefitsgreater than costs. 相似文献

Valuing a change in the risk of death is a key input into the calculation of the benefits of environmental policies that save
lives. Typically such risks are monetized using the Value of a Statistical Life (VSL). Since the majority of the lives saved
by environmental policies are those of older persons, there has been much recent debate about whether the VSL should be lower
for the elderly to reflect their fewer remaining life years. We conducted a contingent valuation survey in the UK, Italy and
France designed to answer this question. The survey was administered in these three countries following a standardized protocol.
Our results suggest that the VSL is €1.022 million or €2.264 million, depending on whether we use median or mean WTP. The
VSL is not significantly lower for older persons, but is higher for persons who have been admitted to a hospital or emergency
room for cardiovascular and respiratory problems. Income is positively and significantly associated with WTP. The income elasticities
of the WTP increase gradually with income levels and are between 0.15 and 0.5 for current income levels in EU countries. We
use the responses to the WTP questions to estimate the value of an extension in remaining life expectancy. The value of a
loss of one year’s life expectancy is €54,000 or €163,000. 相似文献

The article explores the relevance of a particular approach of the institutionalist movement, régulation theory, to deal with the relationship between the economy and the environment. Régulation theory, which appeared in France at the end of the 1970s, is mainly interested in macroeconomic issues. In contrast, until now it has tended to neglect environmental questions. By taking several key concepts of this theory (accumulation regime, mode of régulation, institutional forms), we have sought to assess its significance vis-à-vis the environmental field. More precisely, from the perspective of establishing an environmental regulationist theory, we propose considering the economic relation to the environment as the articulation of three forms: a transhistorical form, a general capitalist form and a specific capitalist form, the latter being variable in capitalist time and space. We give several illustrations of the variability of the relation to the environment, depending on the different accumulation regimes and the different modes of régulation. Two principal avenues of research are proposed: historical analyses for given economic areas, and comparative analyses relating in particular to different capitalist areas. 相似文献
