农村集体经营性建设用地价格影响因素的实证分析*——基于江西省余江县179份交易案例

[目的]确定农村集体商服用地、工业用地价格的影响因素,为科学评估农村集体经营性建设用地地价、构建城乡统一建设用地市场提供参考。[方法]利用全国农村土地使用制度改革试点之一的江西省余江县179个交易案例,运用特征价格模型分析农村集体商服用地、工业用地价格的影响因素及各类因素的贡献率。[结果](1)农村集体商服用地价格的主要影响因素依次为乡镇财政收入、人均纯收入、到客运站距离、到国道的距离、教育设施;农村集体工业用地价格的主要影响因素依次为人均纯收入、人均农村居民点面积、到客运站的距离、到国道的距离。(2)社会经济因素、区位交通因素和公共设施因素对集体商服用地价格的贡献度分别为69. 0%、20. 4%和10. 6%;社会经济因素和区位交通因素对集体工业用地价格的贡献度分别为52. 8%和47. 2%。[结论]总体上与国有城镇建设用地价格存在共性规律,但存在部分因素与国有建设用地价格规律存在差异,农村集体经营性建设用地估价不宜完全套用城镇建设用地的思路。     

全域旅游示范区空间分布特征及影响因素分析

［目的］全域旅游示范区的确立为旅游业增添了新的旅游吸引模式，成为新时期我国旅游产业转型升级的重要途径之一。［方法］文章利用ArcGIS102，运用最邻近距离法、不均衡指数、核密度分析、等方法，对标记在地图上的500个全域旅游示范区的空间分布特征进行分析，并探究其空间分布差异的影响因素。［结果］（1）示范区空间分布不均衡，呈典型的聚集型分布，从区域角度来看，西部地区示范区数量多于东部地区，中部地区相对较少，与传统认知上的示范区分布格局存在一定错位； （2）示范区空间分布密度存在明显差异，其中江浙皖、湘赣交界、晋豫交界、陕渝交界等地区示范区聚集最多，形成显著的高密度区； （3）示范区规模度差距较大，上海、北京、江苏、天津等省市规模度较大，其他省市规模度较小； （4）示范区空间分布受到资源禀赋、区位交通、社会经济、政策环境等因素影响较大，呈现“傍景”“环路”的分布格局。［结论］全域旅游示范区空间分布不均衡，各省市既要挖掘自身核心竞争力，也要加强区域协调发展，突出示范区模范带头作用，达到辐射周边市县的效果，实现全域旅游资源优化配置。     

Forecasting using heterogeneous panels with cross-sectional dependence

In this paper, we focus on forecasting methods that use heterogeneous panels in the presence of cross-sectional dependence in terms of both spatial error dependence and common factors. We propose two main approaches to estimating the factor structure: a residuals-based approach, and an approach that uses a panel of auxiliary variables to extract the factors. Small sample properties of the proposed methods are investigated through Monte Carlo simulations and applied to predict house price inflation in OECD countries.     

Oil price shocks and economic growth: The volatility link

This paper shows that oil shocks impact economic growth primarily through the conditional variance of growth. Our comparison of models focuses on density forecasts. Over a range of dynamic models, oil shock measures and data, we find a robust link between oil shocks and the volatility of economic growth. We then develop a new measure of oil shocks and show that it is superior to existing measures; it indicates that the conditional variance of growth increases in response to an indicator of the local maximum oil price exceedance. The empirical results uncover a large pronounced asymmetric response of the growth volatility to oil price changes. The uncertainty about future growth is considerably lower than with a benchmark AR(1) model when no oil shocks are present.     

The fair value of a token: How do markets price cryptocurrencies?

With the rise of cryptocurrency tokens as a new asset class, the question of the fair evaluation of a cryptocurrency token has become a question of increasing importance. We estimate the pricing kernel with which users price factors affecting their token holdings. We investigate how traditional risk factors such as market risk are evaluated, as well as how blockchain specific risk factors are priced in. In order to do so, we introduce an asset pricing model and modify its properties to make it applicable to cryptocurrency markets. We group the risk factors into market related and Bitcoin- and Ethereum blockchain specific risk factors. We find that blockchain specific risk factors are priced in. There is evidence that risk factors have moved from Bitcoin to Ethereum specific risk factors with an increasing importance of market factors, providing evidence for a decoupling of on-chain and off-chain trading activity.     

Influence of Ecuadorian Homosexual Subculture in Consumption Culture: Study about Information Consumption on Twitter

Abstract

This qualitative research examines the Ecuadorian homosexual subculture and determines how gender, images, texts, and objects are referred to consumption culture. The netnography method was used to collect data from Twitter conversations. Categorization and classification of the conversations showed how the information was created, the purpose of the message, and the target audience. Results reveal common subjects in relation to news, human rights, and gender equality. Subjects were conceptualized based on the consumption of information in social, cultural, and political environments. It was concluded that images, texts, and objects included in the conversations provide significant information about the homosexual subculture consumption behavior.

农户参与乡村旅游扶贫的影响因素研究——以福建省赤溪村为例

以福建省赤溪村农户为调研对象,运用相关性检验和二元Logistic回归模型对影响农户参与乡村旅游扶贫的因素进行研究。研究发现:农户参与乡村旅游扶贫的比例较高,但是旅游经营的项目单一;农户的学历、劳动力数量、地理位置、参与乡村旅游扶贫培训的次数对农户参与乡村旅游有显著地正向影响作用;农户生计资本和对旅游发展的感知中的权力关系、可借款能力、家庭年收入、了解乡村旅游扶贫政策、有资源用于发展乡村旅游也是影响农户参与的主要因素。在此基础上,提出了加大扶贫政策宣传力度,提高旅游扶贫政策利用程度完善旅游相关基础设施,扩大农户扶贫资金来源渠道,完善扶贫资金体系,完善旅游供给侧创新旅游经营模式,实行多项扶持的针对性建议。

中国近海捕捞业技术效率影响因素分析——基于省级面板数据

基于我国沿海11个省份2008-2011年近海捕捞业投入产出数据,利用随机前沿分析方法研究了渔船"双控"政策、生产补贴、渔船吨位、近海污染等各种政策、技术与环境因素对我国近海捕捞业技术效率的影响。发现渔业生产保障能力和捕捞渔船纳入双控比例与技术效率正相关,户均补贴收入、捕捞渔船吨位、省域近海污染比例等与技术效率呈倒U型关系,农村人均收入与技术效率负相关。提出了切实消减过剩捕捞能力、严控近海污染、控制成本类补贴增长、完善近海捕捞业保障基础等政策建议。
