产业集群驱动的工业化道路——重新解读“温州模式”

通过对“温州模式”的研究,发现温州遵循“开放-发现-创业-扩散-升级”这样一条产业集群驱动的工业化道路,其发生机理是由于开放,增加了同外部市场接触的机会,发现了市场信息并完成了初始资本的积累,当企业家能人出现、开始在某地创业时,本地工业化进程便随之启动。     

Short-time at-the-money skew and rough fractional volatility

The Black–Scholes implied volatility skew at the money of SPX options is known to obey a power law with respect to the time to maturity. We construct a model of the underlying asset price process which is dynamically consistent to the power law. The volatility process of the model is driven by a fractional Brownian motion with Hurst parameter less than half. The fractional Brownian motion is correlated with a Brownian motion which drives the asset price process. We derive an asymptotic expansion of the implied volatility as the time to maturity tends to zero. For this purpose, we introduce a new approach to validate such an expansion, which enables us to treat more general models than in the literature. The local-stochastic volatility model is treated as well under an essentially minimal regularity condition in order to show such a standard model cannot be dynamically consistent to the power law.

Experience and a firm's performance in foreign markets: A commentary essay

Wu and Lin (2010) extend several prominent themes in the experience and subsidiary performance literature in their empirical examination of the foreign expansion of Taiwanese MNEs. This commentary essay considers the themes in Wu and Lin (2010) against the backdrop of the considerable volume of research that has been conducted on experiential learning and firm performance in both the international business and strategy literatures. Five weak axioms about the relationships between experience, foreign market entry strategy, and performance emerge in this review. Based on these weak axioms, the commentary concludes that scholars need to concentrate future research on understanding the management and process-related issues that concern the effective management of a firm's experiential learning processes to foster better capability and knowledge development from a firm's experience, as well as translate such developments into improved performance prospects for a firm.     

FOREIGN ENTRY,CULTURAL BARRIERS,AND LEARNING

This paper examines the longevity of foreign entries. Hypotheses are developed on the mode (start-ups vs. acquisitions) and ownership structure (wholly owned vs. joint ventures) in relation to cultural distance. The hypotheses are tested within a framework of organizational learning, using data on 225 entries that 13 Dutch firms carried out from 1966 onwards. Results show that the presence of cultural barriers punctuates an organization's learning. Cultural distance is a prominent factor in foreign entry whenever this involves another firm, requiring the firm to engage in ‘double layered acculturation.’ We also identify locational ‘paths of learning.’ The longevity of acquisitions is positively influenced by prior entries of the firm in the same country. Similarly, the longevity of foreign entries, in which the firm has a majority stake, improves whenever the expanding firm engaged in prior entries in the same country and in other countries in the same cultural block.     

经济欠发达地区商业银行信贷业务拓展与创新研究——以安徽信贷市场为例进行分析

从余额、增量、增幅、人均信贷水平等不同维度看,安徽信贷市场规模较小,但是面临巨大的发展空间。拓展和创新欠发达地区信贷市场需要重视四个方面:第一,在国家货币信贷政策上对经济欠发达地区信贷市场的扩展给予促进和推动;第二,大型商业银行的总行在制定区域信贷政策和分配贷款限额时,要对其在经济欠发达地区的分支机构实行倾斜;第三,欠发达地区各级政府要大力加强诚信社会建设,确保投资者和债权人合法权益,增强其投资信心和收益预期;第四,商业银行要建立适应欠发达地区信贷市场快速发展的信贷营销机制和信贷管理机制,确保信贷市场健康持续发展。

基于软件无线电平台的1090ES扩容信号收发处理

随着空中交通的信息传输与新应用拓展需求不断增加,1090ES信号容量有限问题日益显现,对1090ES信号进行容量扩充是一种有效解决途径。针对一种基于脉内调相的1090ES信号扩容技术,给出了叠加调制的信号模型,研究了1090ES信号的解调解码算法;在GNU Radio+ USRP软件无线电平台上,实现了1090ES扩容信号的产生和接收处理,包括脉冲位置调制（Pulse Position Modulation,PPM）与8PSK叠加调制、低通滤波、报头检测、载波同步、PPM解码和相位解调等,并利用Matlab对实验的解码错误率和信号的频谱特性做了统计分析与仿真,结果表明了该扩容技术的可行性。
