How to inhibit a partner's strong and weak forms of opportunism: Impacts of network embeddedness and bilateral TSIs

This study investigates the moderating effects of a firm's network embeddedness and a partner's transactional specific investments (TSIs) on relationships between the firm's TSIs and its partner's strong- and weak-form opportunism, and compares the efficiency among these moderator variables. The regression results suggest that (1) a firm's TSIs are positively related to partner's opportunism when network embeddedness and the partner's TSIs are relatively low; but (2) a firm's TSIs are negatively related to partner's opportunism when network embeddedness and the partner's TSIs are relatively high. Furthermore (3) network embeddedness is more effective in inhibiting partner's weak-form opportunism than in inhibiting strong-form opportunism resulting from the firm's TSIs. Finally (4) with regard to the relationship between TSIs and weak-form opportunism, the negative moderating effect of network embeddedness is greater than the negative moderating effect of partner's TSIs. This study explains reasons why conflicting views exist about the relationship between TSIs and partner's opportunism, reveals the differences in the moderating effects of network embeddedness and partner's TSIs, and makes new contributions to both transaction cost theory and embeddedness literature. It also provides, for firms involved in TSIs in a buyer–supplier relationship, insightful managerial suggestions about ways to reduce their partner's varying forms of opportunism.     

3-羟甲基四氢呋喃的合成研究

3-羟甲基四氢呋喃是合成第3代烟碱类杀虫剂呋虫胺和核苷类抗病毒药物喷昔洛韦的关键中间体,但长期以来由于使用大量金属硼氢化物造成生产成本高、安全风险高、废物多等缺点。以γ-丁内酯为原料,经Aldol缩合、硼氢化钠还原两步反应得到3-羟甲基四氢呋喃,总收率为51.9%,该法中间体α-羟甲基-γ-丁内酯只有一个内酯羰基需还原,原料γ-丁内酯和甲醛价廉易得,整个工艺路线适于工业化。

Chemical Fiber： Better lhan Expected

According to China Chemical Fiber Industry Association, during the first half year of 2014, China＇s chemical fiber output has been keeping steady, the benefit has been turning better in comparison to the first quarter of this year, the new production of polyester amounted to 2.62 million tons, upstream suffered imbalance between supply and demand, and some large enterprises have been afflicted with capital chain issues etc. The association forecasts annual production will reach 43500 thousand tons, up by 6% roughly, the gross profit will increase over last year and the operational quality will improve.

Intelligence in Textile Machinery Industry

The development of textile machin- ery industry, at present, is in dilemma to some extent. For instance, the amount of newly-commenced projects is on the decline, which witnessed a year on year decrease by 0.96% in the past half year of 2014. It can be attributed partly to the rising cost of labor and raw material, and thus the product prices cannot be as pleased as before. In this manner, many small enterprises have difficulty in find-ing clients, only to have rising stocks. Therelbre, they are obliged to have more days off as to tion. It may be is due partly to ing market. maintain tile deduced that daily opera- this dilemma the neglect of the changing market.     

基于SARIMA-SVR组合模型的 空气质量指数预测

空气质量指数(AQI)在波动中既具有整体的时间序列线性特征和明显的季节性波动周期,又具有多种因素影响的不确定性,为了提高AQI的预测精度,基于Ri386 3.3.3和Matlab R2014a两种编程软件,提出了一种同时具有线性和非线性的复合特征的时间序列预测模型——SARIMA-SVR组合模型。以太原市2014年1月—2019年7月的AQI月均值数据为基础,利用SARIMA时间序列模型进行线性预测,利用SVR模型对残差进行非线性预测,加和得到组合预测模型的预测结果,分析比较SARIMA,SVR和SARIMA-SVR这3种模型的预测结果和平均绝对百分比误差。结果表明,组合预测模型发挥了2种模型各自的优势,相较于单一预测模型的预测结果而言,其预测精度更高,稳定性更好。通过此模型得到的空气质量预测结果不仅可为人们的日常生活提供指导,而且可为大气污染的防治工作提供科学依据和借鉴意义。     

创新团队公平感知与知识共享行为关系研究——以成员信任为中介变量

创新团队组织形式的蓬勃发展使得团队成员的绩效激励方式成为众多管理者的研究课题。团队中掌握独特隐性知识的成员往往不愿意共享自身的有利于团队的创新知识,从而给团队的发展带来困难。如何针对这类员工做出有利于团队整体绩效提升的激励活动,是创新团队管理者和所有创新团队工作模式研究者的共同目标。通过数据模型的回归,得出如下结论:创新团队的成员公平感知与成员知识共享行为正向相关,成员对互动公平的感知对知识共享行为的影响最为显著。验证了创新团队成员信任在成员公平感知与知识共享行为之间的中介效用。

Do ongoing networks block out new friends? Reconciling the embeddedness constraint dilemma on new alliance partner addition

Research Summary: This study addresses a theoretical dilemma regarding how alliance network constraint (reflected by network cohesion) affects a firm’s alliance formation with new partners. Using a network pluralism approach, we separate a firm’s ego alliance network into two activity‐based networks—an exploratory network and an exploitative network—based on the primary value chain activity involved in each alliance. We argue that the cohesion of exploratory or exploitative networks has an inverted U‐shaped effect on the addition of new partners in the same activity‐based network, and a positive effect on the addition of new partners in the other network. Results based on data from the biotechnology industry largely support our predictions with one exception. Our study contributes to both scholarly understanding of network embeddedness and alliance practice. Managerial Summary: The structure of firms’ ongoing alliance networks may have paradoxical implications for their efforts to search for and form alliance with new partners. That is, when a firm’s alliance partners are tightly connected with each other, the cohesive network tends to both encourage and impede the focal firm to add new partners. We resolve this dilemma by showing that when a firm is deeply entrenched in a cohesive alliance network conducting a certain type of activities (e.g., R&D activities), it may not easily add new R&D alliance partners. However, it may still be able to escape from the cohesive R&D alliance network by seeking new partners conducting other activities (e.g., manufacturing activities).
