Creative destruction: Identifying its geographic origins

The fate of regions and industries are often intertwined. When industries thrive, regions and their constituents benefit. However, when industries decline, regions often require new paradigms to replace the old paradigms, and infuse new economic life into the region. This study enhances understanding of the regional characteristics that hinder or promote creative destruction. It enlightens the field on the geographic origins of creative destruction by theorizing about a region's structural (determined by industry clustering and regional knowledge), social demography and political economy attributes, and their influence on the region's capacity to incubate creative destruction.     

企业技术创新悖论及其网络机制干预研究

随着市场环境的日趋复杂多变及竞争的日益激烈,技术创新成为提升企业竞争力、促进企业成长和效率非线性提高的重要途径。组织结构是影响企业技术创新能力的重要因素。企业技术创新管理面临着技术和组织上的两难悖论,即企业越是追求高新技术,就越是导致企业偏重内部结构并导致部门之间的隔离,从而越是阻碍了企业技术创新;高生产率、产品商业化创新和创新信息管理都需要一个严格等级分明的组织,而新技术发明和创意都要求比较灵活机动的、非等级制的组织形式。企业内外的合作网络机制是解决技术创新的两难悖论、提高创新绩效的关键。     

我国战略性新兴产业发展如何避免低端锁定——以风电设备制造业为例

近年来我国的风力发电等战略性新兴产业取得了快速发展,但由于内源性技术创新能力不足、技术高度战略化与产品低市场利基的矛盾等原因,使得战略性新兴产业发展面临低端锁定的风险。本文以风电设备制造业为例,通过分析全球的竞争格局以及我国以引进技术支撑规模制造优势、通用零部件的生产优势与关键零部件的进口依赖并存等参与全球价值链的特征,得出距离战略性新兴产业的标准仍有不小差距。为避免低端锁定,本文提出关键共性技术的战略性攻关、赋予龙头企业创新责任与创新激励等六条风电设备制造业实现价值链攀升的路径。

Assessment of Adoption Gaps in Management of Aflatoxin Contamination of Groundnut (Arachis Hypogaea L.)

Abstract

One of the major impediments for diversification of groundnut (Arachis Hypogaea L.) as food crop is aflatoxin contamination. The study was conducted with an objective to assess the adoption gaps in aflatoxin management practices of groundnut (AMPG) and the farmer's characteristics influencing these gaps. The study used an expost-facto research design and multi-stage random sampling. The data were collected from 180 respondents through interview schedule. For measuring adoption gap, knowledge of AMPG and perception of groundnut quality suitable scales were developed. The data were subjected to multiple regression analysis to know the characteristics, which influenced the adoption gaps in AMPG. The majority of farmers were in high adoption gap category, as most of the farmers had not adopted the harvest and post-harvest management practices. Farmers' characteristics such as knowledge, market orientation and innovativeness influenced the adoption gap significantly. These three variables put together explained 58% of variation in adoption gap. Based on the results, it is suggested to formulate strategies to increase the knowledge of farmers through various extension approaches. If the knowledge on AMPG is improved the adoption gaps can be reduced. The maiden research effort, shed light on the socio-economic dimensions of aflatoxin contamination and constraints for aflatoxin management at farmers' level. The study has significance for the policy makers, extension departments and groundnut farmers for production of quality groundnut.     

Fractional order sliding mode control of a pneumatic position servo system

Gas flow has fractional order dynamics; therefore, it is reasonable to assume that the pneumatic systems with a proportional valve to regulate gas flow have fractional order dynamics as well. There is a hypothesis that the fractional order control has better control performance for this inherent fractional order system, although the model used for fractional controller design is integer order. To test this hypothesis, a fractional order sliding mode controller is proposed to control the pneumatic position servo system, which is based on the exponential reaching law. In this method, the fractional order derivative is introduced into the sliding mode surface. The stability of the controller is proven using Lyapunov theorem. Since the pressure sensor is not required, the control system configuration is simple and inexpensive. The experimental results presented indicate the proposed method has better control performance than the fractional order proportional integral derivative (FPID) controller and some conventional integral order control methods. Points to be noticed here are that the fractional order sliding mode control is superior to the integral order sliding mode counterpart, and the FPID is superior to the corresponding integral order PID, both with optimal parameters. Among all the methods compared, the proposed method achieves the highest tracking accuracy. Moreover, the proposed controller has less chattering in the manipulated variable, the energy consumption of the controller is therefore substantially reduced.     

Delineating policy mixes: Contrasting top-down and bottom-up approaches to the case of energy-storage policy in California

In the light of pressing societal challenges such as climate change and resource scarcity, scholars are increasingly interested in studying policy mixes in the context of sustainability transitions. However, despite numerous conceptual advances and empirical insights, researchers still lack universal criteria or accepted heuristics for delineating policy mixes in these complex policy spaces. We address this gap by conducting an extensive review of the literature, synthesizing best practices, and developing an analytical framework that provides researchers with two archetypical methodological approaches. The top-down approach builds on the idea that the elements of a policy mix originate from an overarching strategic intent. By contrast, the bottom-up approach starts from the definition of a focal impact domain that is affected by a range of policy instruments. For each approach, we outline a systematic analytical procedure, then implement it to scrutinize how policy affects the emerging technological domain of energy storage in California. We find that each approach has particular advantages that render it useful for certain policy mix analyses. Discussing how researchers may choose between the two approaches or leverage their complementarities, we seek to provide the basis for a consistent research program building on the policy mix framework.
