针对当前产业结构研究的局限和不足,本文率先在该研究领域引入了社会网络的研究方法。通过社会网络与投入产出表的有机结合,提出了一种全新的、基于"关系"和"结构"视角的产业结构研究方法。利用我国2002年的投入产出数据和本文提出的研究方法,对我国产业结构的总体特征进行了实证研究。利用块模型分析方法,阐明了我国产业八大区块的范围和边界;刻画了我国产业总体结构的"中心化趋势",并对位于中心的产业进行了说明;提出了"最佳替代产业"和"自反性"产业区块的概念和实例,并分析了其在国家产业结构调整和优化过程中如何发挥各自的优势和作用。  相似文献   

家族性因素对家族企业绩效影响的实证研究          下载免费PDF全文

辛金国  潘小芳  管晓永 《科研管理》2014,35(11):118-125

家族企业在世界经济中占有重要的地位,研究者相信家族企业具有不同于非家族企业的独特性,于是将其区分出来进行单独研究。但目前的研究多只是简单地探讨家族企业独有的企业特征与非家族企业相比较所具有的优势或劣势,较少研究家族性因素对企业绩效的影响。本文通过文献研究及访谈调研,提出了家族性因素的四个维度,在此基础上构建了家族性因素与企业绩效的关系的研究框架,提出各因素与企业绩效的关系假设。最后,通过问卷调查获取家族性因素及企业绩效的数据,用SPSS13.0软件系统对各个因素与企业绩效之间进行相关性分析,偏相关分析,回归分析,以检验假设。研究表明"家族性因素"中信任度、家族成员间的交流、职业经理模式、愿景共享与企业成功和家族成功均有显著的正相关关系,而人情取向、柔性治理模式、多元化经营与企业成功和家族成功显著负相关关系。  相似文献

Matrix approach to verification of finite multi-potential games     

《Journal of The Franklin Institute》2022,359(5):2229-2243

This paper studies the verification of multi-potential games with a given partition, and proposes a kind of multi-potential equation based on semi-tensor product of matrices. Firstly, the basis of each player’s potential function is constructed, based on which, a new formula is established for the calculation of each player’s potential function. Secondly, a new potential equation is proposed for the verification of potential games via each player’s potential function. Using the new potential equation, a kind of multi-potential equation is constructed for the verification of multi-potential games with a given partition. It is proved that a finite game is a multi-potential game with a given partition if and only if the multi-potential equation has solution. In addition, all possible potential functions are obtained for each group of the partition. An illustrative example is worked out to show the effectiveness of the obtained new results.  相似文献   

A robust predictive observer-based integral control law for uncertain LTI systems under external disturbance     

《Journal of The Franklin Institute》2022,359(13):6915-6938

The integral control is an effective way to track non-zero constant reference. In this paper, to utilize a robust predictive integral control strategy in the output-feedback case, the control requirement and the goals are formulated in a suitable form. Then, by introducing a novel matrix transformation, the controller designing issue is translated into an optimization problem subjected to some constraints. Such constraints are represented in terms of linear matrix inequality (LMI). By solving a minimization problem, the gains of the integral controller are determined and updated at some time instants. Finally, several numerical simulations are given to evaluate the advantages of the suggested robust control method over similar ones. The outcomes confirm the superiority of the proposed idea compared to the existing approach.  相似文献   

Event-Triggered privacy-preserving average consensus for continuous-time multi-agent network systems     

《Journal of The Franklin Institute》2022,359(10):4959-4975

This paper deals with the privacy-preserving average consensus problem for continuous-time multi-agent network systems (MANSs) based on the event-triggered strategy. A novel event-triggered privacy-preserving consensus algorithm is designed to achieve the average consensus of MANSs while avoiding the disclosure of the agents’ initial states. Different from the approaches incorporating stochastic noises, an output mask function in the proposed algorithm is developed to make initial state of each agent indiscernible by the others. Particularly, under the output mask function, all agents can exactly tend to the average value of initial states rather than the mean square value. Under the proposed algorithm, detailed theoretical proof about average consensus and privacy of the MANSs are conducted. Moreover, the proposed algorithm is extended to nonlinear continuous-time MANSs, and the corresponding results are also derived. A numerical simulation eventually is performed to demonstrate the validity of our results.  相似文献   

Finite-time convergent zeroing neural network for solving time-varying algebraic Riccati equations     

《Journal of The Franklin Institute》2022,359(18):10867-10883

Various forms of the algebraic Riccati equation (ARE) have been widely used to investigate the stability of nonlinear systems in the control field. In this paper, the time-varying ARE (TV-ARE) and linear time-varying (LTV) systems stabilization problems are investigated by employing the zeroing neural networks (ZNNs). In order to solve the TV-ARE problem, two models are developed, the ZNNTV-ARE model which follows the principles of the original ZNN method, and the FTZNNTV-ARE model which follows the finite-time ZNN (FTZNN) dynamical evolution. In addition, two hybrid ZNN models are proposed for the LTV systems stabilization, which combines the ZNNTV-ARE and FTZNNTV-ARE design rules. Note that instead of the infinite exponential convergence specific to the ZNNTV-ARE design, the structure of the proposed FTZNNTV-ARE dynamic is based on a new evolution formula which is able to converge to a theoretical solution in finite time. Furthermore, we are only interested in real symmetric solutions of TV-ARE, so the ZNNTV-ARE and FTZNNTV-ARE models are designed to produce such solutions. Numerical findings, one of which includes an application to LTV systems stabilization, confirm the effectiveness of the introduced dynamical evolutions.  相似文献
