欠发达地区产业结构变动对生态足迹的影响——基于云南省的案例实证分析

以云南省为例,综合运用生态足迹、VAR模型和广义脉冲响应函数等模型与方法,在研究云南省三次产业产值与生态足迹变动特征的基础上,进一步分析三次产业产值变动对生态足迹的影响,结果表明:①在近20年来云南省三次产业产值呈现较快增长的趋势下,云南省总量生态足迹也呈现逐年增长的态势.其中,耕地、草地和化石能源用地生态足迹对总量生态足迹的贡献较大,但增长速度相对缓慢;相反,林地、水域和建筑用地生态足迹对总量生态足迹的贡献较小,但呈现较快增长趋势,三次产业经济的较快发展对生态足迹及其要素变动的影响显著.②短期内三次产业发展对生态足迹的影响程度从大到小依次为第一产业＞第二产业＞第三产业,且三次产业对生态足迹的影响均为正向相关性,但长期来看,第三产业的发展有助于降低区域生态足迹.因此,为推进云南省区域低耗、低碳经济科学持续健康发展,实现区域经济社会与资源环境协调可持续发展,提出应大力发展高原现代特色农业和集约农业,建立具有区域特色的外向型工业园区群,加速推进以旅游业和服务业为主的第三产业的发展进程,向国家申请给予生态补偿和产业补偿政策.     

THEMEQUAL—Adapting the SERVQUAL Scale to Theme Park Services: A Case of Hong Kong Disneyland

Faced with keen competition in the theme park operating environment, operators have realized the necessity of maintaining a high standard of service quality in order to survive. Because of the scarcity of literature on theme park service quality, the present study adapts the SERVQUAL model and modifies it as the THEMEQUAL model to measure the gap between perceived service quality and expected service quality from visitors under the theme park setting. The Hong Kong Disneyland is selected due to its importance to the Hong Kong tourism industry. The impact of the dimensions of the model on visitor satisfaction is also examined. Results expressed visitor satisfaction in terms of physical environment, but signified dissatisfaction on employee performance. Among the six dimensions of the model, “responsiveness and access,” “assurance,” and “empathy” are the critical predictors of visitor satisfaction. Discussions on the findings are presented and managerial implications are explained in detail.     

Banking systems,innovations, intellectual property protections,and financial markets: Evidence from China

One unique feature of the emerging economies in Asia is the rich variation in the development of financial systems and technological sectors across different geographical areas. This unbalanced evolution provides us a potentially more powerful setting to investigate the dynamics among banking systems, innovations, intellectual property (IP) protections, and stock market reactions that are especially useful in understanding the policy–finance–innovation nexus in emerging economies. Using newly available data from China, this study confirms the nurturing role of financial systems on innovations, the value-enhancing function of firms' innovative activities, and the lead–lag predictive role of innovations on stock returns, in the context of emerging economies. More importantly, the study documents that stronger provincial IP protections reduce patent piracy and hence enhance local firms' market values.     

农民工主观幸福感及其影响因素分析——基于安徽省黄山市休宁县农民工调查

文章采用随机街访、定向抽查和逻辑回归计量模型分析方法对安徽省黄山市休宁县190户农民工进行实地调查,分析农民工的主观幸福感及其影响因素。结果表明家庭年平均收入、自尊和社会支持、受教育程度和人格特征对农民工主观幸福感的影响显著;年龄、性别和健康状况对农民工主观幸福感的影响不显著。     

订单农业:违约、风险与治理机制——基于E-R模型的天津市国宗梦得合作社的分析

在我国转型过程中,由于市场机制的不健全以及转型前后体制制度之间的不耦合,使得市场经济主体利用制度漏洞违反合约,造成交易过程中的违约和高风险。尤其是农业产业化订单合同中的农户一方主体存在严重的违约动机。文章在E-R模型的基础上,实证分析了天津市国宗梦得农副产品配送合作社合同中订单农业的违约问题解决机制,建议必须从农户自身的选择性偏好入手,建立一套完备的契约选择机制,从根本上解决农户违约行为,引导农户和企业自身积极主动地走向履约之路。     

施用蔗渣对土壤镉赋存形态和生物有效性的影响研究

采用化学反应的合成方法向蔗渣中引入巯基官能团,并进行电镜扫描和红外光谱分析。在此基础上,通过土壤培养试验和生物盆栽试验,研究了蔗渣和改性蔗渣对模拟镉（Cd）污染农田土壤中镉的赋存形态和生物有效性的影响。结果表明,采用该合成方法,成功地向蔗渣中引入了巯基官能团。在土壤培养试验中,有机物对土壤Cd赋存形态的转化与土壤pH的相关性不明显,但与土壤中胡敏酸（HA）和富里酸（FA）含量的变化具有一定的相关性：土壤中HA含量随培养时间的延长而逐渐升高,各处理土壤弱酸提取态Cd含量相应减少,而土壤残余态Cd含量则逐渐增加,且巯基蔗渣的作用效果均强于未改性蔗渣。在生物盆栽试验研究中,外加5 mg·kg-1 Cd显著降低了小白菜的生物量,而施用有机物料对小白菜均有显著的增产效果,研究结果同时表明蔗渣和巯基蔗渣都不同程度降低了土壤有效态Cd的含量以及小白菜地上部分的镉含量,且巯基蔗渣的作用效果较为显著。另外,小白菜地上部分镉含量与小白菜生物量呈现显著负相关,与土壤有效镉含量呈显著正相关。     

Budgeting—the Role of Trust and Participation: A Research Note

Prior studies have found a combination of an evaluative style with high budget emphasis and high participation to be associated with better behavioural outcomes (e.g., lower job-related tension) than all other combinations of budget emphasis and participation. Yet there has been little research to investigate the theory on why this particular combination of budget emphasis and participation is associated with better behavioural outcomes. A path analytical model, which investigates the intervening effects of trust and participation on the relationship between budget emphasis and job-related tension, was used. Senior Norwegian managers were selected as subjects for this study. The results indicate that budget emphasis has an insignificant direct effect on job-related tension but a strong indirect effect through trust and participation. Trust also has an intervening effect on the relationship between budgetary participation and job-related tension. It is therefore possible to conclude that high budget emphasis is associated with high budgetary participation and high trust. High trust, in turn, is associated with reduced subordinates' job-related tension.

经济增长、模型再造与中国经济增长方式的转变

经济增长理论是社会经济发展的一种理论反映,源于斯密和李嘉图为代表的古典经济学派,是二战后在发达国家广泛流行的经济理论,大体经历了三个发展阶段.现代经济增长理论及模型的建立强调科学技术进步、人力资本积累对经济增长的促进作用.但是,发达国家经济学家自身存在的认识论缺陷使其不可能科学完整的建立经济增长理论及模型,因此必须遵循马克思的方法论从理论为实际的反映入手建立科学模型,并以此指导中国社会经济技术实践,特别是经济增长方式的转变实践.     

过程噪声对融合航迹性能的影响

本文研究动态系统过程噪声对航迹统计距离和状态融合估计性能的影响。由过程噪声产生的航迹互协方差矩阵的运算量较大，甚至占到航迹融合总运算量的一半，所以在实现系统时应尽量避免互协方差矩阵的在线计算。文中估计并比较了互协方差矩阵、统计距离及状态融合估计的运算量，仿真研究了观测噪声对航迹统计距离和状态融合估计性能的影响。仿真结果表明在过程噪声较小而对融合航迹性能的影响有限时，可考虑忽略过程噪声的影响，这样将大大降低运算量，反之则不能忽略。
