This is a very stable social relations, however, limited in scope, this is a &quot;strong relationship &quot;; the same time, there is another type of social relations relative to the former shallow, but there is much more extensive social relations, Granovetter to the latter as&quot; weak relationship &quot; ? Found: in fact the cause of a person&#39;s work and social relations most closely is not the &quot;strong relationship&quot;, but often the &quot;weak ties.&quot; &quot;Weak relationship&quot; Although not as &quot;strong relationship&quot; as solid (pyramid), but has extremely fast, may have low cost and high efficiency of transmission. In fact, the proliferation of information dissemination, weak ties play the same role. One&#39;s circle of friends and family who may know each other, therefore, in such circles, the exchange of information provided by others is always redundant. For example, I heard from this friend or relative, and may already have heard of another friend, and they all talk to each other than between this topic. No shortage of daily life such examples.

Closest circle of friends, and you may live almost, your life is almost completely overlap. To meet those long-suppressed people, who may have a lot of you do not understand the situation. Only these &quot;weak relationship&quot; exists, the information can be spread in different circles. Herein lies the power of weak ties. Relationship is usually strong connections between actors that have a high degree of interaction, the interaction of some type on the existence of more intimate, so strong relations generated by the message is often repeated, self-contained closed system is easy . As a member of the network have a similar attitude, high degree of interaction frequency is usually the original understanding of the views will be Jiang Hua was reduced and with the other point of view integration in the organization so that the network is not a strong relationship can provide innovative opportunities in ways. .

Do not know since when, all of the msn or qq signature became a platform for information dissemination: a securities company&#39;s financial analyst job vacancies occurred, someone had just returned to find the four returnees audit of a person to find business school teacher, a Dong Building, set to sell the whole ... ... This is the strength of weak ties is not a complete stranger on the release of information, but you can not say with a soul mate, but also have an associated person to push your career turning point. Might say, how widespread our weak ties, determines how we stage. &quot;And we know better, but not close friends who provide us with new opportunities&quot; 里德霍夫曼 (reid hoffman) in relation to this topic on the very weak voice, he is well-known U.S. professional people linkedln founder of social networking sites. This site established business relationship between the professional network of people, &quot;people can create relationships to achieve a definite purpose, this relationship is known as weak ties. For example 来 说 , bob is cindy and fred&#39;s friend, fred understanding joe and michelle, michelle they know sara, sara and then something on the help of the bob, this is the role of weak ties. &quot;he said. In Hoffman seems, is that we recognize but not close friends with a &quot;weak relationship&quot; provides us with more new opportunities. In real life, one&#39;s social network decided that the person&#39;s survival and development of this relationship in which the strong relationship between network members in their personal character, family composition, educational background, work situation, education information and details such as the situation they have a relatively high level of understanding of social resources.

Excerpt: The works of sociologist Mark ? There is a link to play a role in reflecting the wonderful example. In his excellent research work in 1974, &quot;a job&quot; in the Boston suburb of Granovetter interviewed several hundred professional workers, technical workers, details about their employment experience. He found that 56% of those interviewed who were to have gained through personal relationships work. Another 18.8% of the people is the use of formal channels - recruitment advertising, executive search firm - find jobs, about 20% of the interviewees are their own to apply for jobs directly. Best to pull strings is through personal relationships, it is not surprising. However, Gelannuowei Patel surprise, he found that the majority of people use personal relationships are &#39;weak ties&#39;. Those who use personal relationships among those looking for work, only 16.7% of those seeking help with their own (if this person is your friend) &quot;often&quot; travel, 55.6% of people only &quot;occasionally&quot; to see the supplicants. There are 28% &quot;rarely&quot; to see to pull strings to help their own people. Moreover, by friends is usually a job, generally have 12 plane by the turn of the people found new jobs. Why? Granovetter that, in order to understand the situation a new job or the work of the new information or new ideas, &quot;weak relationship&quot; is always better than the role of a strong relationship more. After all, a friend and you know about the situation. ... ... On the other hand, acquaintance, by definition, and a large circle of your life not the same. They may know something you do not understand the situation. This apparent contradiction to capture the exact meaning of Granovetter coin a catchy: the power of the weak link.
