1 美国生产厂商及现状 美国生产厂商及产能见表1. 乙酸乙酯的产量具有极大弹性,这是因为乙酸乙酯可以与其他醋酸酯类用同样的生产设备生产,其产量主要取决于市场需求量.大多数工业生产的乙酸乙酯是用乙醇酯化乙酸法或作为正丁烷液相氧化副产乙酸乙酯的方法来获得,但也有一些由乙醛缩合制得. 相似文献

Viral marketing is used to widely distribute content. To achieve this goal, the basic decision‐making process from content reception to interaction must be clarified. This paper examines the decision‐making process of individuals in viral marketing using a new dynamic model. In addition, this work reviews the existing literature on viral marketing and structures to identify existing issues for further research. The decision‐making process is basically divided into two stages. In the first decision stage, individuals decide whether content should be considered. When individuals agree to view the content, they decide in the second stage whether they want to interact with it. These two decisions are influenced by three factors: the framework conditions, content, and interaction aims. With the help of the decision model, this paper summarizes the most important findings from viral marketing research over the last 20 years. In addition, this work provides new opportunities for further research in the field of viral marketing. 相似文献

Ilsoon Shin 《Small Business Economics》2006,26(3):241-256
Due to the rapidly changing business and IT environments, firm-level adoption of IT shifted from in-house development to purchasing
EA software. This paper analyzes the effects of EA (Enterprise Application) software – ERP, CRM, SCM, Groupware, KM, EAI –
on SMEs’ productivity. The distinct feature of this paper is that I use a formal econometric approach with combined data of
SMEs’ accounting and IT usage aspects, while case studies have been mostly used in the previous works. The empirical results
show that Groupware and SCM significantly raise the SMEs’ productivity, and the manufacturing sector has stronger effects
than the service sector. From these results, the following implications are derived. First, the adoption rate and the real
benefits of EA software are not closely related domestically. Second, in SMEs, EA software facilitating the inter-firm relationship
is more effective than EA software focusing on the internal efficiency. Third, easy-to-understand, and relatively long-experienced
enterprise applications are more effective than hard-to-understand and brand-new applications. Finally, the government IT
policy on SMEs should focus on the process coordination and standardization of the manufacturing sector with upstream and
downstream firms. 相似文献

This paper draws out lessons from the euro area (EA) that are transferable to the Eastern Caribbean Currency Union (ECCU) and other Caribbean economies with fixed exchange rates. Based on observations from both the EA and the ECCU, we present a new policy framework which is capable of imposing fiscal discipline, with the aim of avoiding the risk of unsustainable fiscal policies reappearing and of preventing monetary policy from being undermined by undisciplined national governments. In the ECCU case, we find that fiscal deficits are more a result of financial and trade imbalances than fiscal indiscipline per se. Consequently, constraints on overall debt, public and private, rather than direct limits on endogenous public deficits, appear to be the appropriate response. 相似文献
