农地整合确权促进农村劳动力就地转移了吗?——基于农业分工的调节效应

本文基于"产权界定方式——分工——农村劳动力就地转移"的分析线索,利用广东省阳山县和新丰县2232户农户问卷调查数据,采用Tobit模型和OLS模型,实证分析了农业分工调节下农地整合确权对农村劳动力就地转移的影响,并运用倾向匹配得分模型(PSM)进行内生性检验。结果发现,整合确权有利于农村劳动力就地转移,农产品市场化程度和农业社会化服务程度的提高增强了农地整合确权对农村劳动力就地转移的正向激励。因此,发挥农地确权对农村劳动力转移效应既要考虑确权进度,也要关注确权方式,注重提高农产品市场化程度和农业社会化服务程度,以此加快农村劳动力就地转移进程。     

Resource integration optimization of convenience service platforms adopting dynamic service modes in new retail

This paper analyzes the key issues of resource integration, and proposes a method for solving the problem of achieving efficient resource integration for convenience service platforms that adopt dynamic service modes. This method considers both the service level of collaborative resources under dynamic service modes, and collaborative resources’ satisfaction of service modes in the resource integration. In addition, dominant factors needing the most attention during resource integration under dynamic service modes are excavated. Moreover, a model for resource integration optimization is established, and ant colony algorithm is used to solve the problem. Finally, a case is used to verify the feasibility of the method.     

Using Malmquist index to select the strategic partners in vertical integration: the case of Taiwan LED supply chain

In recent years, green technology efficiency has been one of the most interesting issues when referring to energy saving. The light-emitting diode (LED) is one of the competitive industries on green technology in Taiwan. The objective of this article is to select the vertical strategic partners of the 22 LED companies through investigating performance of integration. The Malmquist productivity index (MPI) is used to evaluate the average efficiency change from 2011 to 2015. The empirical results show that the productivity change was influenced by both catch-up effects and frontier effects. For upstream companies, the MPI of Tekcore is superior to others because it maintained technical efficiency and technological change. For downstream companies, most of them are performed well in technical efficiency than technological change. This article helps LED manufacturers select the appropriate strategic partners to achieve competitive advantage.     

立法坚持“把党的领导融入法律制度”

"党的领导"是社会主义法治的政治原则和立法准则,政治属性是立法工作的第一属性。立法践行"党的领导"原则,"把党的领导融入法律制度",体现在立法工作和实际操作的诸多方面:党领导和控制立法项目的确定和启动;立法以党的组织机构作为工作核心主体,展开起草、修改和协商等工作程序;法律法规草案制定需要以党的精神、理念和主张作为基本依循来明确立法理念、目的和制度设计;立法将"党言党语"转化为"法言法语",形成条款内容;立法以各种规范形式明确表述和保障"党的领导"。通过立法机制、程序和法文本,体现党对法律制度的领导力和法律制度对"党的领导"的融入水平。     

中国特色城市化道路的研究述评

随着城市化的快速进行,城市生活也出现了一些问题,日益引起了国内外学者的关注,推动各人文学科纷纷转向对城市化的考察,促进了城市研究范式的转变。国内外学者对于中国城市化道路的研究涉及城市化发展进程、城市化建设、城市化区域平衡、城市化问题、城市化发展战略等,也有些学者对中国城市化内涵、城市化特征、城市化的提升路径做了探讨。城市化涉及经济、政治、社会、地理等很多学科,所以,很多学科都对中国城市化道路做了研究。研究中国特色城市化道路,不仅有助于推动城市化理论的整体性研究,而且有利于实现城市化质量的提升、探索城乡一体化的路径。     

Is regional integration in the CFA zone sustainable?

This article aims to study the long-term sustainability of regional integration in the (Communauté Financière Africaine) CFA zone, based on the theory of the endogeneity of monetary zones. To this end, we consider trade and intra-CFA migration as the two quantitative vectors of regional integration. Using robust estimation techniques to overcome the endogeneity bias, our results show that integration in the CFA zone is moderately sustainable. More precisely, while the monetary unions of the CFA zone, in particular that of the WAEMU, contribute to reinforcing the intra-regional mobility of goods and people, they fail to induce strong synchronization of the macroeconomic cycles.     

High and low prices and the range in the European stock markets: A long-memory approach

This paper uses fractional integration techniques to examine the stochastic behaviour of high and low stock prices in Europe and then to test for the possible existence of long-run linkages between them by looking at the range, i.e., the difference between the two logged series. Specifically, monthly, weekly and daily data on the following five European stock market indices are analysed: DAX30 (Germany), FTSE100 (UK), CAC40 (France), FTSE MIB40 (Italy) and IBEX35 (Spain). In all cases, the order of integration of the range is lower than that of the original series, which implies the existence of a long-run equilibrium relationship between high and low prices. Further, multiple breaks are found in the high and low-price series but no breaks in the range, and the estimated fractional differencing parameter is positive in all cases, which represents evidence of long memory.     

Weighted utility optimization of the participating endowment contract

ABSTRACT

In a participating endowment contract, the special loss compensation and profit sharing mechanism leads to heterogeneous benchmarks to distinguish the gain and loss for the policyholder's and the insurance company's S-shaped utilities. Because of the intense competition among the insurance companies and the requirement of the regulators, the benefits of the policyholders should be considered. As such, choosing the weighted utility of the two counterparts as the optimization objective is a rational setting. This setting induces a non-HARA (hyperbolic absolute risk aversion) and non-concave objective utility whose exact concavity and convexity are unknown. The difficulties not only come from this highly non-concave optimization problem, but also exist in the implicit integration of the optimum when solving the expected utilities of the two counterparts. We originally design an identification method to establish two categories of concave envelopes to solve the optimization problem, and propose an innovative numerical integration by substitution technique to deal with the implicit integration problem. The numerical simulation results recognize the existence of Pareto improvement of the two counterparts, which shows that the utilities of the policyholder and the insurance company can be simultaneously improved by switching into the weighted objective and appropriately amending the contract.

The theory of monetary integration

Research dealing with the theory of monetary integration is reviewed. After briefly describing the genesis of the theory as foreshadowed in work on optimum currency areas, the paper assesses two main areas of recent research — the analysis of the effects of disturbances on participating countries in a currency area, and reputational considerations. With regard to disturbances, the paper finds that it is difficult to draw clear-out inferences from theoretical work on the optimal degree of exchange rate management and from empirical studies on the effects of shocks. Work on reputational issues is found to suffer from conceptual problems and has generated empirical results that have not supported the hypothesis that participation in a currency area is a sufficient condition to enhance reputation.
