新型农业经营主体的多维发展形式和现实观照

培育新型农业经营主体是在"四化同步"发展、农产品价值链升级、建立完善新型农业社会化服务体系背景下的必然选择。家庭农场、农民专业合作社和农业企业等多种形式新型农业经营主体的产生有其理论基础。应从加强组织领导、加大金融扶持、优化农技服务、完善基建配套等方面来培育新型农业经营主体。     

融资约束与中国制造业企业出口——基于Heckman样本选择模型的经验检验

本文从非正规金融贸易信贷的研究视角切入,构建衡量企业融资约束的应收账款相对比例指标,研究融资约束对中国制造业企业出口的影响效应。运用Heckman样本选择模型控制样本选择偏误,本文对2004～2007年11.8万家中国制造业企业的分析表明:融资约束制约了中国制造业企业的出口行为,并且这种制约作用存在显著的企业规模指向性、地区指向性、行业指向性和所有制指向性。本文的结论为我们理解融资约束与出口之间的关系提供了中国经验。     

企业参与精准扶贫能促进企业创新吗?

本文以2013-2019年中国A股上市公司为样本,研究企业参与精准扶贫对企业创新的影响.研究发现,企业参与精准扶贫能显著提高企业创新绩效.通过机制检验发现,企业参与精准扶贫能通过财政补贴、税收优惠、银行贷款、股权融资四种渠道来缓解企业融资约束,进而促进企业创新.进一步就企业扶贫方式对企业创新绩效的影响研究发现,企业产业扶贫对企业创新绩效的促进作用最强,教育扶贫次之.本研究能够为企业在后扶贫时代制定扶贫策略和创新发展战略提供参考依据.     

Dynamics of the UK natural gas industry: System dynamics modelling and long-term energy policy analysis

We present a dynamic model of the indigenous natural gas industry in the UK. The model has been built using a system dynamics approach. Using the model several scenarios have been analyzed. We found that management of the supply-side policy alone cannot substantially postpone the discovery, production and consumption peak. We also found that the dynamics of the main variables, namely, exploration, production and consumption, are sensitive to initial demand conditions. Postponing the onset of gas price increases can therefore be achieved more effectively through efforts to reduce demand growth. One might expect that a low taxation policy would encourage more exploration and production of gas and thereby stimulate higher consumption rates. Instead, there was no overall net effect on production and consumption in the long term. The depletion effect on cost of exploration acts as counterbalance to low taxation policy. Depletion effect causes cost and thus price to rise further which depress consumption rate. The advances in exploration and production technology can delay the peak of exploration, production and consumption. Technological improvements mean lower cost of exploration and production which pressure down the long-term pattern of price dynamics.     

当代西方主流职业教育思想及启示

西方主流职业教育思想主要有以巴洛夫为代表的学校形态职业教育思想和以福斯特为代表的市场化、多元化职业教育思想,这些思想对于我们深入研究职业教育的调控手段和方式、职业教育的本质和目标、职业教育思想和模式等问题具有重要启示。     

中国的工业生产力革命--用随机前沿生产模型对中国大中型工业企业全要素生产率增长的分解及分析

本文运用中国大中型工业企业 1 995— 2 0 0 2年期间的年度企业数据 ,系统地研究 3. 7个两位数工业行业的全要素生产率 (TFP)增长趋势 ,并用随机前沿生产模型 ,将生产率增长分解为前沿技术进步 (FTP)、相对前沿技术效率 (TE)的变化、配置效率 (AE)以及规模经济性 (SE)四大因素。主要结论 :(一 )TFP的行业加权年均增长率为 6. 8% ,并呈逐年上升的趋势 ;(二 )前沿技术进步已经成为TFP增长的最重要动力 ,企业因前沿技术进步平均每年提高全要素生产率高达 1 4个百分点 ;(三 )企业相对前沿的技术效率差距拉大 ,已经严重阻碍了TFP增长 ,导致TFP平均每年下降 7个百分点 ,这既是挑战 ,也是反映今后企业通过追赶先进技术提高生产力的潜力。 (四 )企业投入要素的配置效率对TFP增长几乎没有贡献 ,年均贡献仅为 0 . 0 2个百分点 ,而企业的规模经济性对TFP的贡献也仅为负 0 . 3 3个百分点 ,这与前沿技术进步和技术效率变化对TFP的影响相比都微不足道。分析表明 ,前沿技术进步一方面推动着生产力的快速增长 ,另一方面却加剧了企业间的技术效率差距 ,导致更激烈的市场竞争压力。世纪之交的中国最重要的工业企业正经历着一场以前沿技术进步及追赶先进企业为核心的生产力革命。     

创新要素流动与产业结构变迁关系及其空间溢出效应研究

创新要素流动既是优化资源配置的关键,又是产业结构调整的内在动力,反之,产业结构变迁又会通过微观效应推动创新主体创新。基于1998-2018年内地30个省市面板数据,研究了创新要素流动与产业结构变迁的互动关系及空间溢出效应。回归结果表明：R&D人员流动对本地区产业结构高级化以及其它地区产业结构合理化具有促进作用,同时,抑制了本地区产业结构合理化与溢出地区产业结构高级化;R&D资本流动对本地区产业结构高级化以及其它地区产业结构合理化具有抑制作用,但是对本地区产业结构合理化以及其它地区产业结构高级化具有促进作用;产业结构合理化对R&D人员及R&D资本流动具有促进作用,但是抑制了其它地区的R&D资本流动。

Determinants and outcome of career competencies: Perspectives of hotel managers in China

This study aims to explore the determinants and outcome of career competencies. Based on the notion that organizations and individuals have respective obligations in the career management of employees’, this study developed perceived “organizational career management’ (OCM) and “career commitment” as determinants and career satisfaction as an outcome of career competencies. Data were collected in the state-owned hotels in China, and structural equation modeling was used to test the proposed relationships. The findings indicate that both perceived OCM and career commitments have positive, direct effects on career competencies. The findings of this study may benefit both hotels and hotel employees by providing valuable implications.     

From hotel career management to employees’ career satisfaction: The mediating effect of career competency

The purpose of this study is to explore the relationships between perceived hotel career management, career competency, and career satisfaction. It also aims to examine the mediating processes through which hotel career management contribute to employees’ career satisfaction. Results from structural equation modeling (SEM) show that career competency mediates the effects of three dimensions of hotel career management (career appraisal, career development, and career training) on career satisfaction. The article concludes with implications for theory development and management practice.
