产业融合的识别方法研究——基于系统论的研究视角

产业是一个由技术、产品、企业与市场等要素构成的系统，产业融合是开放产业系统中，新奇的出现与扩散引起不同产业构成要素之间相互竞争、协作与共同演进而形成一个新兴产业的过程，其外延包括技术融合、企业融合、产品融合、市场融合、制度融合等。识别产业融合的原则包括功能与结构、定性与定量等。在定性方面，识别产业融合的方法有序参量判断法，在定量方面，主要有网络分析方法、赫芬达尔指数与熵指数等方法。     

Socio-Economic Gaps within the EU: A Comparison

This research investigates socio-economic gaps between countries of the European Union (EU). The countries, for comparison purposes, are grouped into five sets to find out if the different groupings differ in means and variances. The overall conclusion is that the 15 core combinations outperform the rest when comparisons are made on the basis of 45 socio-economic variables. However, the newly added countries in the enlargement appear to be fairly homogeneous when compared in accordance with the 45 variables. Of special interest is whether the inclusion of Turkey among the newly admitted would have changed the pattern of homogeneity among them. The answer to this question is a guarded yes.      

Growth with many agents and wages paid ex ante

In this paper, we consider a one-sector model of economic growth with several infinitely-lived heterogeneous agents, who are endowed with diverse discount factors as well as preferences over consumption. In line with the classical Ramsey model, agents are not allowed to borrow against future income. Unlike the traditional assumption of ex post wage payment, wages are paid ex ante in our model. We first explain the difference between the assumptions of wages being paid ex ante and wages being paid ex post in the framework of a simple illustrative two-class model. Our main result shows that in contrast to the many-agent Ramsey model with ex post wage payment, the capital stock sequence converges to the steady state stock irrespective of production technology employed by the firms. Further, all impatient agents own zero capital stock, whereas the most patient agent owns the entire capital stock from some time onward. Thus, we have shown that a slight modification in the timing of wage payment in growth models can lead to significant changes in the stability properties of equilibrium dynamics.     

Convergence of the world’s energy use

This paper uses the sequential panel selection method to examine the convergence of the energy use of 107 countries. It contributes by analyzing the order of convergence and the factors affecting the difference in convergence using improved methods. We provide robust evidence to indicate that seven out of ten countries have been convergent during the period examined, and strong decoupling across countries does not exist. Additionally, high-income and upper-middle-income countries show convergence characteristics earlier than lower middle-income and low-income countries. This means that high-income and upper-middle-income countries are the first to achieve steady-state levels by adjusting their industrial structure and adopting new technologies, and energy exporters have dominant control over energy use. We find that energy-exporting countries converge before energy importers do. These results mean that the energy use of most countries is in accordance with the convergence theory. It also shows that GDP per capita, industrialization level and latitude have great impacts on convergence, especially for industrialization. Our research provides a reference for countries around the world to adjust their energy use policies and to realize a rational flow of energy resources.     

中国城市建筑景观与后殖民主义批评——中国城市建筑景观“趋同”的思想根源及其出路

全球化使各个国家和地区之间的文化差异越来越小,呈现一体化的趋势,而城市建筑作为人类现代文化的载体,也有一种趋同的发展势头,由此也引发了人们对传统和本土文化的担忧.我国城市建筑景观也面临着“趋同化”的问题,其深层的原因在于受西方中心意识主导下的现代化思想的影响.后殖民批判理论解构“中心”,主张多元文化共存,这对于从根本上...     

Universal service in Turkey: Recent developments and a critical assessment

The meaning of universal service in telecommunications has changed considerably in the last decade. Technological advances have created the necessity to redefine the legal framework. While the demand for old universal services falls, new and wider services are to be included in the scope of legal obligations such as broadband. In this transformation of public policy toward universal services, political preferences take precedence over economic considerations. Turkey provides a good case in point. In this paper, the authors assess the legal framework of universal services and its institutional structure in Turkey. The tension between enlarging the scope of universal service and pressures on using revenues efficiently is emphasized.

基于空间效应的科技企业孵化器运营效率俱乐部收敛研究

科技企业孵化器在区域间的互动既有利于孵化器运营效率提升,同时又给各地孵化器运营带来新机遇和新挑战。在考虑空间效应情形下,科技企业孵化器运营效率是愈发极化还是更加趋同值得探究。构建Super-SBMDEA模型,测量中国内地29个省份2016—2019年国家级科技企业孵化器运营效率,采用探索性空间分析法探究科技企业孵化器运营效率的空间分布收敛情况。结果发现：中国大多数省份科技企业孵化器运营处于有效状态,效率分布呈现“东高西低”特征。中国整体组和L—L组运营效率呈收敛趋势,但空间效应不显著;H-H组和H-L组运营效率呈收敛趋势,且空间效应显著;L-H组收敛趋势不明显。研究结论表明在空间效应情形下,科技企业孵化器运营效率呈现整体收敛和多稳态趋同的特点。

中国对外贸易发展地区差异的收敛性分析

本文利用收敛σ、β收敛和俱乐部收敛理论检验了中国对外贸易发展地区差异的收敛性.总体而言,1978-2005年中国对外贸易发展存在β收敛但不存在σ收敛,并出现了一定程度的俱乐部收敛特征.究其原因,主要是地区经济发展不平衡、经济贸易体制改革的逐步推进以及各地区发展基础的不同.最后,本文对中国各地区对外贸易的协调发展提出了政策建议.
