Optimal allocation of direct and embodied arable land associated to urban economy: Understanding the options deriving from economic globalization

Land resources do not flow directly but can be allocated as “embodied land” in goods and services during economic globalization. The term “embodied arable land” can help link local land allocation strategies to the global and national supply chains and trade activities, and suggest new lens in optimizing arable land allocation. China is facing a serious arable land shortage, especially in municipal administrative areas. Based on the nested input-output analysis (Nested IOA), this work takes Shanghai as an example, exploring the allocation of direct and embodied arable land of an urban economy within the process of economic globalization. The amount of embodied arable land associated with Shanghai economy is 6.09 Mha, broken down into local arable land use (0.20 Mha), domestic inflows (3.20 Mha) and foreign inflows (2.69 Mha). This area supports local final demand (4.32 Mha), domestic outflows (1.24 Mha) and foreign outflows (0.53 Mha). Land-related imbalances emerge in the study, namely the economy’s demand versus the city’s size, the arable land demand versus supply, and embodied arable land inflows versus outflows. Regarding the role of the urban economy in allocation of global arable land under economic globalization, on the one hand, Shanghai has intensively involved with a large amount of embodied foreign arable land resources, and has been heavy dependent on foreign embodied arable land; On the other hand, there is still large potential for Shanghai to take the opportunity of economic globalization for an optimal allocation of direct and embodied arable land. Policy suggestions on taking the opportunity of economic globalization for an optimal allocation of direct and embodied arable land are put forward.     

“双高计划”呼唤高职院校补齐教师队伍建设短板

教师是兴教之本、立教之源,是实施"双高计划"建设最重要、最直接的力量。大力加强教师队伍建设是高职院校高质量发展的迫切要求。当前高职院校教师队伍存在总量不足、高层次人才短缺、双师素质不高、创新能力不强等问题,必须引育结合、创新机制、激发活力,补齐短板,提升整体实力和水平。     

改造我们的教学

进入"双高时代",我们距离新时代高等职业教育"舞龙头"的教学还有问题和"短板",应该改造教学方法和学习与研究制度。在剖析改造教学原因的基础上,厘清看待教学中存在问题的两种互相对立的态度,提出改造教学的革故鼎新路径,如强化"课堂教学为王"的意识,强化学习与专业研究,强化教学的职业素养,强化教师的课堂教学治理。     

海外高层次人才创新创业政策研究:政策工具与创新创业过程视角

在全球人才流动加速的知识经济时代，中央和地方政府相继颁布了一系列鼓励海外高层次人才创新创业的政策。通过构建政策工具—创新创业过程二维框架，以浙江省“九五”至“十三五”期间颁布的海外人才政策为研究对象，采用内容分析法和扎根理论编码进行统计分析。研究发现：浙江省海外高层次人才政策数量增长迅速，从“十五”至“十三五”开局之年政策数量呈明显上升趋势;政策发文主体较多，但协调性较弱，浙江省财政厅是重要联合发文主体;从政策工具维度而言，供给类和环境类政策过溢、需求类政策偏少;创新创业准备阶段缺乏环境型政策，起步阶段缺乏供给型政策，发展阶段缺乏需求型政策。最后，提出优化海外高层次人才政策的对策建议。     

Location choice in low-income countries: Evidence from Japanese investments in East Asia

Unlike most existing studies, this paper examines the location choices of multinational enterprises (MNEs) in low-income countries. Specifically, we investigate the location choices of Japanese MNEs among East Asian developing countries by estimating a four-stage nested logit model and a mixed logit model at the province level. Our findings are as follows. First, Japanese MNEs consider Cambodia, Laos, Myanmar, and Vietnam to be host countries different from China and the forerunners of ASEAN. In other words, for Japanese investors, ASEAN forerunners are countries replaceable by China. Second, the mechanics of vertical FDI are more likely to appear in FDIs in low-income countries. For example, rather than the market size of the host country, tariff rates on products from investing countries are more crucial location elements.     

长三角地区产业结构高级化及影响因素

本文根据三次产业结构比重,构造了长三角江浙沪三地的产业结构层次系数,对三地产业结构高级化变动进行了分析,发现产业结构高级化存在区域差异和趋势趋同特征,继而使用1990—2008年面板数据对影响产业结构高级化的影响因素进行了实证检验。结果发现:科技创新和政府规模对于产业结构高级化有正向作用,进出口贸易对于产业结构升级产生负向作用,FDI和社会投资作用则不太明显。其政策含义在于,在长三角产业结构升级化进程中,更应该注重科技创新和技术进步来推动产业结构高级化发展,从而实现产业结构调整和经济发展转型。

Models and optimal designs for conjoint choice experiments including a no-choice option

In a classical conjoint choice experiment, respondents choose one profile from each choice set that has to be evaluated. However, in real life, the respondent does not always make a choice: often he/she does not prefer any of the options offered. Therefore, including a no-choice option in a choice set makes a conjoint choice experiment more realistic. In the literature, three different models are used to analyze the results of a conjoint choice experiment with a no-choice option: the no-choice multinomial logit model, the extended no-choice multinomial logit model, and the nested no-choice multinomial logit model. We develop optimal designs for the two most appealing of these models using the D-optimality criterion and the modified Fedorov algorithm and compare these optimal designs with a reference design, which is constructed while ignoring the no-choice option, in terms of estimation and prediction accuracy. We conclude that taking into account the no-choice option when designing a no-choice experiment only has a marginal effect on the estimation and prediction accuracy as long as the model used for estimation matches the data-generating model.
