智能制造有利于增加企业技术创新投入吗——基于智能制造试点的准自然实验

智能制造是我国制造业转型升级的主攻方向,而如何准确客观评价智能制造的实施效果成为亟待解决的问题.从技术创新投入视角,将智能制造试点政策实施视为一次准自然实验,采用2011-2019年制造业上市企业面板数据,通过PSM-DID方法研究智能制造对企业技术创新投入的影响.研究结果表明,智能制造显著影响企业技术创新投入,即通过提升客户集成度、供应商集成度进而提高企业技术创新投入,且促进作用仅发生在民营企业和非高新技术行业中.该发现扩展了现有研究外延,同时,为解决当前国际困局和促进智能制造的持续推广提供了重要实践价值.     

Crowdsourcing-based semantic relation recognition for natural language questions over RDF data

ABSTRACT

Natural language query systems over RDF data need to rely on the semantic relations in query. First, we propose the new crowdsourcing model that used to produce semantic relations dataset. The model not only inherits completeness of the iterative model and accuracy of the parallel model, but also saves human resources. Second, we mine the rules of semantic relation recognition from the correlations between dependency structures and semantic relations. Third, we propose an algorithm of semantic relation recognition for natural language query over RDF data, and experiments demonstrate that it can recognize more semantic relations than existing methods.     

"三位一体"全过程工程咨询在港科大(广州)项目中的应用

住房和城乡建设部于2017年5月2日印发了《关于开展全过程工程咨询试点工作的通知》(建市[2017]101号),以及国家发展改革委住房城乡建设部于2019年3月15日印发的《关于推进全过程工程咨询服务发展的指导意见》(发改投资规〔2019〕515号),相关政策的颁发推动了全过程工程咨询业在我国的快速发展.本文以港科大(广州)一期工程为例,组成项目管理、设计咨询、造价咨询为一体(简称"三位一体")的全过程工程咨询联合体,加强风控预防,降低项目风险,提高项目品质,增强行业价值.     

Relative-to-rival corporate philanthropy,product market competitiveness,and stakeholders

Unlike most of the literature that examines the relationship between corporate philanthropy and financial performance, this study investigates the mechanisms through which corporate socially responsible behaviors produce financial outcomes. We propose that corporate philanthropy improves corporate competitiveness by eliciting positive responses from stakeholders, who assess a firm’s philanthropic contribution in relation to its rivals to determine what level of support they wish to provide to the firm. We predict that a firm’s philanthropy relative to its rivals has a positive effect on its product market competitiveness, and that this positive effect is moderated by three conditions that influence stakeholder response: stakeholder attention to philanthropy, its perceived legitimacy, and expectations of corporate giving. Our predictions are generally supported by our analyses. Overall, this paper shows that strategic philanthropy has a quantitative dimension, and firms obtain the market competitiveness associated with corporate philanthropy by integrating their rivals’ positions into their decision making.     

北盘江光照水电站坝肩开挖与安全监测

光照水电站地处高山峡谷岩溶地区,两岸山体陡峻,坝高达195.5 m,故坝肩开挖工程量大,加上地质条件较差、工期紧迫,所以施工技术复杂。为此,对该电站地形地质条件及施工环境进行了认真研究,对坝肩高台阶施工采取了分段开挖的措施,并制定了不良地质部位的处理方法,终于使坝肩开挖满足了工程要求。
