我国建立行政公诉制度探析

从现实需要入手分析了行政诉讼法在实施中存在的问题,由此引出行政公诉的概念,进而根据我国社会经济生活发展的需要和宪法、法律的基本原则和具体规定提出建立以人民检察院为起诉主体,以维护国家及社会公共利益为目的,适合我国国情的行政公诉制度,并据此对行政公诉制度的建立提出初步的设想。     

关于国家大安全观与小康安全建设思路的探讨

全面小康社会并非仅仅是一个富裕程度的概念，还是一个生产力水平、国际竞争力的概念。全面建设小康社会，追求的是物质、精神、生态、安全文明的共同发展。所以。衡量小康社会的标准除了经济指标外，还必须包括关乎国计民生的社会人文指标。

GDP质量的系统分析与改善对策——以甘肃省为例

GDP已经成为世界公认的衡量经济增长速度的指标,但它只是单纯从数量上反映经济增长。GDP外部质量特征主要体现在年平均发展速度、年地区发展的离散系数上;内部质量特征则包括支出法构成、收入法构成、三次产业构成、要素的贡献率、能源和原材料消耗等方面。应综合GDP的内部质量指标和外部质量指标编制GDP综合质量指标评价体系,弥补单一GDP指标的不足。     

自适应聚类视角下学科领域主题分析——以物流学科为例

基于改进关键词重要性和近邻传播聚类算法,提出了一种学科领域主题分析方法,通过词频分析法和作者潜意识行为计算高频关键词权重,借助共词分析和Ochiai系数构建带权重高频关键词相似性矩阵,利用近邻传播聚类算法对学科领域主题进行自适应提取与分析。以CSSCI收录的2015—2019年物流学科领域期刊论文为研究对象,借助新方法对其进行主题分析,研究结果表明:高重要性的关键词不一定是核心主题,核心主题与同一簇内其它成员关键词最为相似。与此同时,近五年物流学科存在“降本增效”“区域物流一体化”“现代物流技术研究与创新”“物流体制改革与产业转型升级”“农村物流与农产品物流”“电子商务与跨境电商”“可持续发展理念”等七大热门主题。     

Labor unemployment risk and firm risk

This paper examines the effect of labor unemployment risk on firm risk. Using unemployment insurance benefits as a proxy for unemployment risk, we find an economically significant positive relation between unemployment risk and firm risk. This positive relation is more pronounced for firms that are more labor-intensive, have a higher layoff propensity and are more financially constrained. While existing literature that employs corporate policy measures such as debt and cash holdings suggests an opposite relationship, our paper presents evidence that the effects stemming from earnings management, earnings quality and reporting quality appear to dominate.     

Do we really care about Biodiversity?

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.

Is Meta-Analysis a Noah's Ark for Non-Market Valuation?

This paper describes meta-analytical methods as they have been appliedto non-market valuation research. These studies have been used to reviewand synthesize literature and, more recently, in benefit transfer. Thissecond use imposes a higher standard on the consistency in economicconcepts being summarized and in the resources included in ameta-analysis. To meet this need, the paper proposes and illustrates astructural framework using a generalized method of moments estimator toestimate the parameters of a preference function with the benefitsestimates usually encountered in meta-analytic summaries.
