Factors affecting agricultural land transfer-in in China: a semiparametric analysis

We use interview survey data collected randomly from 2677 farm households in nine provinces of China to understand the role of demographic, economic, land, and village characteristics on agricultural land transfer-in by farmers. Results show that variables such as borrowing from informal sources, household labour availability, percentage of total income from agricultural sources, and the household with village cadre have significant positive effects on land transfer-in. Low economic development and low transportation network availability in a county reduces land transfer-in. We also find that two variables (land holding and land idling) should be entered into the model nonparametrically. Land holding and land idling have U- and L-shaped impacts on land transfer-in, respectively. Land transfer-in has endowment equilibrium and provides Chinese households more opportunities to earn agricultural income, thereby reducing rural poverty.     

河南省农业生态旅游产业可持续发展评价研究

[目的]河南农业生态旅游作为一种可持续发展的旅游形式,为河南的经济发展作为了重要贡献。对河南农业生态旅游产业可持续发展进行评价研究,是促进农业生态旅游可持续健康发展的重要保证。[方法]文章通过实地调研构建河南农业生态旅游产业可持续发展评价指标体系,运用层次分析法,确定指标权重,结合专家评分法,对各项评价指标打分,并计算河南农业生态旅游产业可持续发展的综合得分,结合农业生态旅游产业可持续发展评价标准,得出目前河南农业生态旅游产业可持续发展水平。[结果]河南农业生态旅游产业可持续发展评价得分为72.45,处于基本可持续发展阶段,并对当前河南农业生态旅游发展现状和存在的农业生态旅游意识淡薄、旅游产品特色不明显、缺少政府资金扶持和缺乏经营管理人才等问题进行了分析。[结论]基于上述问题,提出了提高环保意识、走可持续发展之路;开发特色原生态旅游产品;加强政府支持和引导;加强专业培训,打造专业队伍等对策。     

Size and information revelation in securities trading

We examine differences in information content between order submission sizes and trade sizes by U.S. equity traders. Increasing (decreasing) order submission (trade) size is reflective of information. The result suggests that better-informed traders want to trade in a large size, but that they engage in stealth trading practices or break larger orders into smaller sizes in order to conceal information. While prior studies tend to narrowly focus on trade executions at the market-centre level, our findings indicate that order submission size varies significantly from trade size and that both sizes are informative about future prices, albeit in an inverse manner.     

烹饪原料在烹饪加工过程中水溶性维生素的保存方法研究

水溶性维生素是一类重要的食品营养成分,其含量少、稳定性差、在高温下易被破坏。因此,在烹饪过程中,要注重对水溶性维生素的保护。本文从饮食烹饪角度出发,分析日常烹饪方法对食物中水溶性维生素的破坏,并提出科学合理的烹饪方法。     

无溶剂大豆浓缩蛋白的生产工艺

Does the Reporting Location of Other Comprehensive Income Matter? The Investor's Perspective

In the context of changes mandated by the Chinese Ministry of Finance in January 2009 regarding the location in which other comprehensive income (OCI) is reported, this paper finds that reporting OCI on the performance statement significantly improves its value relevance. The improvement is driven by two OCI items: unrealised holding gains/losses on available‐for‐sale securities and the share of other comprehensive income of investees under the equity method. Our results show that the OCI reporting location matters, which supports the psychological perspective that investors pay more attention to salient information. Our findings lend strong support to the approach of standard setters in reporting OCI on the performance statement.     

Structural transformation in emerging economies: leading sectors and the balanced growth hypothesis

The paper uses the World Input-Output Database to address patterns of structural transformation in BRIC countries, Indonesia, South Korea, Mexico and Turkey. Sectoral drivers of aggregate labour productivity growth, and the relative importance of within-sector versus employment reallocation effects on aggregate labour productivity growth, are evaluated using growth accounting decomposition methods. Decomposition results are used to assess how patterns of structural transformation relate to macroeconomic performance in terms of aggregate labour productivity, output and employment growth. Together with the construction of ‘Hirschman compliance indices’, decomposition results are also used to shed light on the balanced versus unbalanced growth debates. The paper goes on to assess the extent of complementarities between manufacturing and information and communications technology-intensive advanced services through intermediate inputs, comparing the eight emerging countries with G7 countries over time.     

NVC龙企功能升级模式演进及机理纵向案例研究——技术自主性视角

国内龙头企业核心技术自主可控成为制约NVC（国内价值链）功能升级的关键问题。通过文献归纳，以能力自主与产权自主解构技术自主性内涵，并根据产品平台与技术轨道双维度划分NVC龙企功能升级模式。基于“能力—战略—行为—绩效（RSCP）”分析框架，选取华为海思公司作为纵向案例研究对象，探索技术自主性视角下NVC龙企功能升级模式及演进机理。结果发现，模块创新与知识产权创造能力通过产品渐进升级模式提升供应链；架构创新与知识产权布局能力可以调整技术轨道，通过产品突破升级模式I打通创新链；架构创新、模块创新和知识产权运营能力可以变革技术轨道，通过产品突破升级模式II主导价值链。     

基于泰勒规则的人民币套息交易

本文利用泰勒规则对汇率改革以来的人民币汇率进行预测,基于各种预测模型构建模拟的人民币/美元套息交易策略,并依据风险调整收益、最大回撤率和收益偏度等指标来考察各交易策略的获利能力.实证结果表明:基于人民币的套息交易可以获得明显的收益,而基于泰勒规则预测的套息交易收益更佳,它超越了作为比较基准的随机游走模型的表现.考虑了经济基本面中不可直接观测的时变因子的影响作用后,套息交易的收益改善程度尤为明显.这为比较和权衡相关汇率模型的预测能力提供了新的视角.此外,对比在岸市场和离岸市场人民币套息交易的收益表现,说明在人民币利率市场化进程中健全金融监管和对资本账户采取适当管制措施是必要的.
