基于电子鼻技术对调味品中非法添加罂粟壳的检测

采用便携式PEN3电子鼻检测调味品中非法添加罂粟壳。分别对非法添加有不同比例罂粟壳的花椒粉、孜然粉、烧烤粉进行辨别,用线性判别式(LDA)与多层感知器(MLP)两种方法对数据进行分析。结果表明:电子鼻能够较好的识别调味品中非法添加不同比例的罂粟壳,多层感知器相较于线性判别具有更好的区分效果,并且对未知样品进行准确预测。     

Construction of an open innovation network and its mechanism design for manufacturing enterprises: a resource-based perspective

Innovation is the engine of development for enterprises, and there is an increasing trend to adopt an open innovation strategy. However, how to manage external resources in an open, collaborative and complementary manner, and in a shared environment that will yield the greatest networking effects, it is a challenging task. Because there is no such a satisfactory model for an open innovation strategy that combine operational mechanisms with the management of, external resources. Thhis article tries to fill the gap by adopting a resource-based perspective to construct an overall open innovation (OOI) business model. In this model, external resources are classified as industrial and non-industrial entities, to enable the identification of the interaction methods between manufacturing enterprises and external resources. The management of external resources involved in a Technology Open Innovation (TOI) cycle is given particular attention that includes: 1) the classification of the external resources of a TOI, 2) the general mechanisms extracted to promote qualified resources in and unqualified resources out, and 3) a business model to conceptualize the collaboration between enterprises and external resources. A case study of TOI is also provided to empirically verify its feasibility. This paper contributes to the literature by providing an original operational model and mechanism design for an open innovation strategy that is capable of managing external resources effectively.

REGIONAL ANTI‐CORRUPTION EFFORT,POLITICAL CONNECTIONS AND FIRM INNOVATION EFFORT: EVIDENCE FROM CHINA

This paper examines how firm characteristics and local anti‐corruption effort moderate the influence of political connections on enterprises’ private R&D investment using data from 2,587 Chinese A‐share listed enterprises. Our results show that the local anti‐corruption institutional environment significantly moderates the strong relationship between political connections and enterprises’ private R&D investment. Firm characteristics (i.e., firm size and firm age) also show a moderating effect on the relationship between political connection and enterprises’ private R&D investment; larger and older enterprises are more likely to have innovative resources and business cooperation partners, and thus are able to reduce their degree of reliance on political connections and government funding. The results of our study suggest the importance of having a transparent and fair institutional environment for enterprise innovation activities.

西部地区投资效率、投资结构及其机制研究

当前,西部地区已进入投资高峰期,但主流观点认为与高投资相伴随的往往是低效率,如何确保大规模投资更好地拉升区域经济?这就需要提高投资效率。本文通过测算西部各省经济运行效率并与东部省份进行比较,分析西部地区投资动态效率及其形成机制。结果显示西部地区经济运行动态无效,并且西部各省资本配置效率逐渐趋同于较低水平,这些表明了西部地区整体和各省的投资产出效率都极低。分析其原因,主要是投资的行业结构及资金来源结构存在不合理性,因此西部地区若想有效促进经济社会持续发展,就必须将投资机制进行结构性调整。
