农户生态耕种行为及其影响因素研究——以江西省为例

[目的]为清晰识别影响农户生态耕种行为的主要因素,以期为加强耕地生态保护、保障农作物质量安全、提升农户耕种收益、实现农业现代化目标提供参考。[方法]基于江西省11市47县(区)1488份农户微观调查数据,在分析农户生态耕种特征基础上,运用二元Logistic和Probit模型对农户生态耕种行为影响因素开展实证研究。[结果]农户生态耕种10种具体行为的采纳情况差异明显,其中施用有机肥采纳程度最高,生态农业模式采纳程度最低。农户采纳生态耕种整体水平不高,但仍具备进一步推广的潜力。家庭劳动力比重、生态耕种成本认知、新型农业经营主体、法律法规认知、生态耕种收益认知、生计分化和生态环境认知等解释变量是影响农户生态耕种行为的主要内部因素,政府补贴、农田基础设施、生产交流程度、耕地质量变化和生态耕种信息获取难度等则是主要的外部影响因素。[结论]政府及基层管理部门应在推动农户非农就业生计、大力培育新型农业经营主体、加强生态耕种宣传与推广、完善政策扶持与管控机制等方面制定针对性的政策措施。     

老年综合征的评估研究

随着现阶段人口老龄化趋势越来越明显，我国的老年综合征患者数量逐渐增多，《老年综合征管理指南》对老年综合征有相关阐述，认为老年综合征是指老年人因多种非疾病原因或是疾病原因所引起的同一（或临床表现）老年病症，例如睡眠障碍、吞咽障碍、跌倒、褥疮等均属于老年综合征病症。     

A MCGP decision aid for homebuyers to make the best choice

This study adopts a new approach, the multi-choice goal programming (MCGP), to evaluate houses in order to help homebuyers to find better house based on the residential preferences. According to the function of MCGP, homebuyers can set multiple housing goals with multiple aspiration levels. This increases the flexibility to find a suitable house. Compared with other classical methods such as checklist and analytic hierarchy process, MCGP is more efficient, especially while considering a lot of housing criteria and house alternatives. In order to demonstrate the usefulness of MCGP decision aid for housing selection, a real case study is then provided. Furthermore, ten volunteers are invited to participate in the empirical experiment. The results also validate the effectiveness and efficiency of MCGP decision aid.

Local fiscal distress and investment efficiency of local SOEs

In this paper, we use A-share listed firms between 2002 and 2010 to investigate the relationship between local fiscal distress and the investment efficiency of local SOEs, along with the effect of corporate tax payments on this relationship. We find a positive relationship between the extent of local SOEs' overinvestment and the fiscal distress of the corresponding local government where the enterprise and this relationship become stronger for firms that pay fewer taxes. The pattern of underinvestment among local SOEs was in contrast,and these relationships do not exist for non-SOEs or central SOEs. Moreover,we find that expanding a firm's investment scale leads to an increase in total taxes paid, including income and turnover taxes, which further result in more local fiscal revenue. Overall, we conclude that local governments have an incentive to increase fiscal revenue when faced with fiscal distress by raising the investment scale of local SOEs and that the incentives and effects of such interventions appear to be stronger among firms that contribute less to local fiscal revenue.ó 2013 Production and hosting by Elsevier B.V. on behalf of China Journal of Accounting Research.

西北半干旱地区既有城市道路海绵化 改造模式探索——以西宁为例

西宁属于西北高海拔半干旱地区,具有年均降雨量 少、蒸发量高的气候特征。城市道路是城市径流雨水产流的主 要组成部分。西宁现状城市道路均采用传统快排方式,存在雨 水利用不佳、污染城市末端水系生态环境等问题。根据城市道 路等级、下垫面及现状植被生长情况,分析西宁海绵城市建设 试点区道路改造项目的特点,定制城市道路海绵化改造的技术 路线,分类探讨解决西北半干旱地区城市道路初期雨水的径流 污染控制及雨水利用问题。根据已完成海绵化改造的8条道路 的经验,提炼西宁城市道路海绵化改造模式,以期为西北半干 旱地区城市道路海绵化改造提供解决思路。
