Firm efficiency,industry performance and the economy: three-way decomposition with an application to Andalusia

An economy may perform better because the firms become more efficient, the industries are better organized, or the allocation between industries is improved. In this paper we extend the literature on the measurement of industry efficiency (a decomposition in firm contributions and an organizational effect) to a third level, namely that of the economy. The huge task of interrelating the performance of an economy to industrial firm data is accomplished for Andalusia.

Mail survey abroad with an alternative web survey

The large decline in cooperation in surveys experienced in the first decade of the twenty first century has placed representative surveys in a veritable quagmire, although numerous researchers have shown that the decline in the total nonresponse has been much higher in administered surveys (face-to-face and telephone) than in self-administered (mail and web surveys). The move from the “traditional” mail survey to the internet survey has brought important changes, but, at the same time, new challenges have arisen related to the lower coverage and the reduced visibility, the need for certain skills to fill out a questionnaire, changes in response rates, etc. This is a self-administered survey that informs the addressees by mail that they have been selected to participate in a research survey to which they can respond either by using the paper questionnaire (in the letter there is a prepaid envelope), by means of a web questionnaire (accessing a link and using a password), or by telephone (the respondent provided a contact time telephone number via a prepaid envelope or by calling an answering machine). The respondents themselves, therefore, choose the mode of response. An analysis of the responses achieved by each modality shows that the majority of the questionnaires were received by ordinary mail (83.6 %), 359 by internet (14.4 %), and 51 were answered by telephone (2.0 %).     

珠三角纺织行业物流发展现状、问题及其对策研究

珠三角是中国最大的服装生产加工基地、纺织品服装贸易集聚和批发中心,拥有大量的纺织行业民营企业和一定数量的大型企业.随着后配额时代的来临,珠三角纺织工业发展面临更多的挑战与机遇.本文对珠三角地区纺织行业物流发展现状、存在问题进行了分析,并结合珠三角纺织产业物流发展需求,指出必须通过加强纺织集群间合作、推动纺织企业物流共同化、使用物流外包、采用纺织行业电子商务物流和建立自动化仓库提升企业生产效率等方式来发展和提升珠三角地区的纺织行业,并增强其在国际纺织行业市场核心地位与竞争力.     

模拟移动床色谱在拆分奥美拉唑对映体中的应用

以乙醇/二乙胺(100/0.1)为流动相,用纤维素三苯基氨基甲酸酯涂敷型手性固定相在模拟移动床色谱(SMBC)上拆分了奥美拉唑对映体.考察了在保持柱子切换时间不变的情况下,流动相内部流速对分离效果的影响.实验条件下,通过有序地优化SMB各区的流量,S-奥美拉唑的纯度、回收率均大幅度提高.使分离后S-奥美拉唑的纯度最高可达98.71%,R-奥美拉唑的纯度最高为95.47%.     

Stability of Risk Premia in the Italian Stock Market

In this work, we estimate the arbitrage pricing theory (APT) on the Italian Stock Market using the reduced-rank regression technique recently propossed by Bekker et al. (1996). Due to its computational simplicity, this technique allows extensive empirical analysis of the properties of the estimator employed. In this work, we carry out an initial exploration of the cross-sectional stability of the risk premia estimates in relation to the stocks' sample composition. We show that, by choosing an appropriately diversified sample, some acceptable degree of stability may be obtained. We also investigate, using the bootstrap method, the small sample properties of the estimator. (J.E.L.: G11, G12).     

梯度转移理论下我国区域创新极化效应与扩散效应的非对称性影响研究

我国区域创新极化效应和扩散效应存在显著的非对称性影响，即创新极化地区在吸纳创新资源形成极化影响的同时，其反哺作用却十分微弱，未能对创新资源输出地形成对称性的扩散影响，这也是引致我国区域经济发展非平衡的重要原因。为此，我国需要切实打破地缘限制，改善欠发达地区的技术承接环境，通过招商引资积极推动区域间的产业转移，并对创新资源输出地的对称性补偿额度进行科学量化。从而实现我国区域间的创新资源优化配置和区域经济发展非平衡矛盾的最终解决。     

从美国保险市场第三方资产管理看中国保险市场的未来

第三方资产管理模式又称外部委托投资模式，是指保险公司自己不进行投资和资产管理，而是将全部的保险资金委托给外部的资产投资公司进行管理。保险公司则按照保险资金的规模向受委托的投资公司支付管理费用。     

论我国企业技术创新的三大策略

上世纪90年代，我国盛行“以市场换技术”作为企业引进发展技术的主要途径。结果市场让出去了，却未获得先进技术，究其主要原因不外乎两方面：一方面，从跨国公司内在动机及技术战略来看，跨国公司既不可能转让先进技术也不可能让我们掌握落后技术中的关键技术。外资投资于东道国的首要目的是获利，保持其先进技术的垄断优势对跨国公司来说是保持其核心竞争力的关键。因此中国企业很难从跨国公司获得关键性技术。另一方面，由于中国企业发掘引进技术潜力的能力弱，在技术引进过程中，又将主要资金和精力用于硬件设备和生产线的进口，缺乏对引进技术的系统集成和综合创新，这种引技模式并不能真正提升中国企业技术水平，反而对跨国公司的技术形成依赖。
