自然保护区生态旅游发展对贫困农户生产经营能力的影响研究

基于云南省轿子山国家级自然保护区的调查数据,从3个维度构建农户生产经营能力指标体系,运用熵值法及多元线性回归模型研究保护区生态旅游发展对贫困农户生产经营能力的影响。结果表明:轿子山国家级自然保护区样本贫困农户生产经营能力总体处于中等水平,且呈现出区域差异性;社区社会保障缺乏和政府帮扶政策措施滞后是造成农户生产经营能力不足的主要原因;在控制“农户家庭基本特征”类别下的4个变量中,保护区开展生态旅游效果的主客观认知是影响贫困农户生产经营能力的一个重要因素,贫困农户参与保护区生态旅游相关工作正向显著影响农户生产经营能力,并对保护区生态旅游扶贫效果起到中介效应。因此,提出政府相关部门应合理规划,构建全域化生态旅游发展体系;增强基层治理水平,提供就业创业培训路径;转变观念,提升自我脱贫可持续能力等建议。

Pairs trading strategies in a cointegration framework: back-tested on CFD and optimized by profit factor

Statistical arbitrage is based on pairs trading of mean-reverting returns. We used cointegration approach and ECM-DCC-GARCH to construct 98 pairs of 152 stocks of 3 currencies. Stocks trading is done by Contract for Difference (CFD), a financial derivative product which facilitates short selling and provides a leverage up to 25 times. To measure the performance of a leveraged strategy, we introduced the profit factor which is the annualized return rate per unit risk. And the historical risk is measured by maximum drawdown. We compared three main strategies: percentage, standard deviation of cointegration long-term residuals and Bollinger Bands (dynamic standard deviation), with and without double confirmation of short-term standard deviation modelled by ECM-DCC-GARCH. Each of the three main strategies is optimized by two optimizers: absolute profit and profit factor. The optimization period goes from 2012–01-01 to 2014–12-31, and validation period is from 2015–01-01 to 2016–06-01. Our results showed that the USD Bollinger Bands strategy without double confirmation and optimized by profit factor, outperformed other strategies and provided the highest annualized return rate per unit risk; 32% of our sample pairs ended up in loss, and 94% of which are explained by a cointegration break during the testing period.     

Process innovation capability and subsequent collaborative team performance in travel planning: a knowledge exchange platform perspective

Purpose: Backpacker tourism is flourishing in this century as the high development of Internet technology which enables travellers to search for resources they need easier. The research goal of this study was to exam how virtual skill and collective efficacy affect process innovation capability and subsequent team performance of collaborative design team in a virtual community. Design/methodology/approach: In this study, we formulated the virtual team model from the perspectives of open innovation paradigm and virtual competence, and we collected virtual community participation samples from the online communities. Invitation emails were delivered to numerous trip plan initiators in two well-known online travel communities for filling survey questionnaires for this study. In total, 3000 invitation messages were mailed, of which 373 were returned completed. The model and hypotheses were tested by structural equation modelling. Findings: Virtual competence, including collective efficacy and virtual media skill, is the essential key to facilitate process innovation capability and subsequent team performance success. Besides, knowledge sharing significantly moderates the relationship between process innovation capability and the team performance. Originality/value: Backpackers in the online travel communities have to have not only the willingness to collaborate, but also the abilities of using the correct tool to help with their tasks. When a self-efficacy gets into collective efficacy, it enables the collaborative team to develop with good virtual competencies. Accordingly, trip plan initiator and participants of a virtual team are as expertise contributors between conformity in online communities and online compulsive control tendencies.

现代职业教育视野下,对建筑企业教育培训工作的探讨

当代社会,企业之间的竞争归根到底是人力资源的竞争,企业为了能在激烈的市场竞争中独占鳌头,使尽浑身解数,其中员工培训就是极其重要的一种手段。然而,大多数建筑企业培训无论是战略层面还是操作层面,违背现代职业教育的规律,难以对培训进行科学有效的管理。本文结合现代职业教育的相关理论,围绕员工"智能倾向定位"、"能力本位定位"等内容,探讨职业教育理论在建筑企业培训中的应用,强调"行动导向"培训方法的重要性。     

林权流转价格及其影响因素分析

以林农拥有的活立木为研究对象,利用2007—2017年浙江省1546宗活立木流转样本,采用多元线性回归实证分析了是否在林权交易中心交易对活立木流转价格存在影响。结果表明:关键解释变量是否在林权交易中心进行交易对活立木流转价格具有显著的正向影响;流转面积、单位面积蓄积、区域虚拟变量、坡度等对流转价格都产生一定程度的影响;流转期限对流转价格的影响不大。因此,需要加强对林权交易中心的宣传,降低相关的交易成本,从而吸引更多的小规模林农参与交易。     

When do retail investors pay attention to their trading platforms?

Buying and selling securities through online trading platforms has become increasingly popular among U.S. households in recent years. This study tracks U.S. households' attention to their online trading platforms using daily data for 2004 to August 2017. The analysis covers the 10 most popular online trading platforms among U.S. investors. The findings indicate that market shocks, captured by several proxies, as well as macroeconomic announcements attract investors' attention to trading platforms. We also document that the ostrich effect weakens when considering greater changes in the VIX. Our findings do not support the avoidance of information theory, but do support the theoretical argument that risk-averse agents engage in more information gathering when uncertainty prevails in hopes of reducing their risks.     

Key drivers of innovation capability in hotels: implications on performance

Innovation capability is critical for the modernization and competitiveness of the hotel industry. This work analyzes the role of hotels' innovative culture, market orientation, and internal marketing as forerunners of innovation capability in hotels, as well as the effect of innovation capability on hotels' performance. The proposed conceptual model is evaluated through structural equation modeling using a sample of 256 Spanish hotels. The results reveal that innovative culture by itself is not a key driver of the hotels' innovation capability. However, internal marketing and market orientation mediate the innovative culture-innovation capability relationship. Innovation capability proves to enhance hotels' market results directly and indirectly through customer equity. Our findings offer hotel managers useful guidance to understand how innovation capability is built within the firm by combining the right organizational culture and practices. Additionally, our study reinforces the financial and non-financial benefits of innovation capability in hotels.     

高质量发展视角下区域创新能力的提升路径 ——以南京市江宁区为例
