The social impact management plan as a tool for local planning: Case study: Mining in Northern Finland

The paper discusses social impact management plan (SIMP) as a planning tool for communities to continuously and adaptively manage and address the diverse social changes caused by mining developments. It introduces an empirical case study, where the SIMP is applied to deal with the possibilities and problems that the mining boom has created in a rural, sparsely populated municipality in Northern Europe. The making of the SIMP n the Sodankylä Municipality was the first community-led policy programme focused on mining in Finland. After collaborative planning with relevant stakeholders and political decision-making process, a SIMP laying out shared visions and mutually agreed actions was given the status of an official policy programme in 2018. However, there are several uncertainties related to the realization of the SIMP. From the viewpoint of governance dependencies, there are still differing opinions among the local stakeholders, including the mining companies, about what socially sustainable mining actually means and demands. Also, communities are often left with no other choice than to adapt to the interdependencies inherent in local governance, national legislation and politics. They also have to get used to international economic fluctuations and to the uncertainties intrinsic to the global production and consumption of metals. Nevertheless, the SIMP is a worthwhile effort to achieve the best local solutions related to mining in the northernmost parts of Europe.

A Profit Function Approach to Wage–Risk Differentials

Abstract

A variable profit function is used in a novel way to estimate wage–risk premiums in Ohio bituminous coal mining. Unlike the dominant hedonic method, the profit function does not assume equilibrium and allows inferences about the marginal opportunity cost of accidents to mining companies. The profit function risk premium, expressed as a value of a statistical life (VSL), is $12,000 (in 1915 prices), and is below published estimates covering this period. The hedonic method is also used and yields a very similar VSL, a robustness check. It is also shown that the use of piece rate–based wages of coal loaders (the main group of miners) yields more plausible hedonic estimates than the fixed daily wage of “inside” miners typically employed.     

基于R语言主题模型的光伏产业创新政策层级性特征分析

以光伏太阳能产业为例，运用R语言主题模型，对国家、山西及大同3个层级政府2007—2019年光伏产业创新政策进行主题挖掘和量化分析，研究不同层级产业创新政策间的关联特征。结果表明：国家级政策主要集中于宏观价格管制和财政补贴制度，政策指导性特征明显；山西省级政策集中于中微观扶持性层面，政策指令性特征显现；大同市级政策主要集中于具体的微观运行机制，政策管控属性更加明显。上述政策特征与产业创新政策总体要求一致，但3个层级政策热门主题间还存在相关性不强、政策间互动影响作用不明显等问题，忽视了产业创新政策的传导渗透性特征。     

Analysis of the perceived value of online tourism reviews: Influence of readability and reviewer characteristics

Online reviews provide additional product information to reduce uncertainty. Hence, consumers often rely on online reviews to form purchase decisions. However, an explosion of online reviews brings the problem of information overload to individuals. Identifying reviews containing valuable information from large numbers of reviews becomes increasingly important to both consumers and companies, especially for experience products, such as attractions. Several online review platforms provide a function for readers to rate a review as “helpful” when it contains valuable information. Different from consumers, companies want to detect potential valuable reviews before they are rated to avoid or promote their negative or positive influence, respectively. Using online attraction review data retrieved from TripAdvisor, we conduct a two-level empirical analysis to explore factors that affect the value of reviews. We introduc a negative binomial regression model at a review level to explore the effects of the actual reviews. Subsequently, we apply a Tobit regression model at the reviewer level to investigate the effects of reviewer characteristics inferred from properties of historical rating distribution. The empirical analysis results indicate that both text readability and reviewer characteristics affect the perceived value of reviews. These findings have direct implications for attraction managers in their improved identification of potential valuable reviews.     

煤炭资源采矿权随机便利收益估价模型

煤炭资源采矿权的有偿取得和转让是社会主义市场经济发展的客观必然,科学合理有效地对煤炭资源采矿权进行估价,是煤炭资源采矿权有偿取得和转让的关键和前提。煤炭资源采矿权具有和股票看涨期权一样的期权特性,本质上是一种按年度执行的多期看涨期权。便利收益的变动将直接影响煤炭资源采矿权价值,固定不变的便利收益或不考虑便利收益都不能准确地反映煤炭资源采矿权价值的变化。假定便利收益服从均值回复过程,文献[7]建立了便利收益和煤炭价格均随机变动的煤炭资源采矿权估价双因素模型,但该模型很难获得解析解,只能简化处理。本文界定了便利收益的内涵及其对煤炭资源采矿权价值的影响,运用鞅定价理论建立了基于随机便利收益的煤炭资源采矿权估价双因素模型,获得了解析解,并通过实例进行了运用,结果表明该模型较DCF方法和煤炭资源采矿权单因素模型更能体现资源所有者的权益。

矿产资源价值组成与矿产资源开发战略

我国在矿产资源产品国际定价权问题上的教训表明,很多地方政府在矿产资源开发方面存在战略上的错误,这种错误源于对矿产资源的价值认识不足.矿产资源的价值包括了它的稀缺价值、时间价值和空间价值等往往容易被人忽略的价值组成部分.比照人们打理稀世珍宝的策略,我国现阶段要采取"富人经济"思想指导矿产资源开发.而这种开发战略的实施手段之一就是实行矿产资源价值补偿,保证矿产资源稀缺价值、时间价值和空间价值的正常体现.
