关于深化农电体制改革的建议

总结了我国农电体制改革在构建农村供电所或营业所、促进农业经济发展等方面的成效,分析了县级供电企业存在的政企未完全分开、股份制改革困难较多、产权关系复杂等问题,提出在深化农电体制改革的过程中,应优先考虑上划方式结束对县级供电企业的代管,明晰农电资产所有权,对农电工管理采用农电业务外包方式,建立有效的农电投融资机制及合理的农村电价形成机制。     

The effects of strategic and market complementarity on acquisition performance: evidence from the U.S. commercial banking industry, 1989–2001

Most traditional research on mergers and acquisitions tends to focus on the role of similarity in explaining acquisition performance. While scholars have recently begun to examine acquisition complementarity, there is still little evidence concerning how complementarity influences acquisition performance. Further, previous research has not drawn the connections between related contexts and the potential benefits from complementarity. In this article, we move the study of acquisition complementarity forward by investigating the effects of strategic and market complementarity on acquisition performance in the context of related horizontal acquisitions. We also propose that two key attributes of acquirers—strategic focus and out‐of‐market acquisition experience—will moderate this relationship. We investigate our research questions in the context of all 2,204 acquisitions made by publicly traded U.S. commercial banks during the 12‐year period from 1989 to 2001. Our findings are generally supportive, suggesting complementarity is an important antecedent of acquisition performance, and raising important issues on the nature of acquisition research in general.

深化柴油降冷凝技术提高柴油对国家标准的符合性

在由低标号柴油生产高标号柴油过程中,为使其凝点、冷滤点更好地符合标准要求,向轻柴油中添加多种柴油流动性改进剂（又称降凝剂）后,针对轻柴油感受性较差的问题,在经过多次实验的基础上,分析原因,提出了深化柴油降冷凝技术措施。该措施实施后,提高了柴油冷凝性对标准的符合性。     

How does the partner type in R&D alliances impact technological innovation performance? A study on the Korean biotechnology industry

The number of strategic alliances for R&D activities in the biotechnology industry is sharply increasing. Some studies show that each alliance partner type has different alliance motives, resources and capabilities, organizational structures and cultures, and degrees of competition with partners, which can lead to different performances of strategic alliances. In this regard, this study conducts an empirical analysis of the different impact of each type of alliance partner on technological innovation performance and finds the moderating effect of absorptive capacity and potential competition by categorizing strategic alliances for R&D activities in the biotechnology industry into three types: vertical-downstream alliances, vertical-upstream alliances, and horizontal alliances. This study analyzed 206 Korean biotechnology firms and their strategic alliances for a total of 292 R&D activities. The results of the analysis showed that vertical alliances have a positive impact on technological innovation performance, while horizontal alliances have an inverted U-shaped relationship with technological innovation performance caused by the effect of competition. Additionally, it was confirmed that the R&D intensity of biotechnology firms has a moderating effect of increasing the impact of vertical-upstream alliances on technological innovation performance.
