- Sphere of influence
A sphere of influence (SOI) is an area or region over which an organization or state exerts some kind of indirect cultural, economic, military or political domination. Also, in some areas of habitation, shopping or retail outlets or indeed destination outlets, have a sphere of influence over towns of certain areas, for example the
Central business district (CBD). A country within the "sphere of influence" of another more powerful country may become a subsidiary of that state and serve in effect as asatellite state or de factocolony . The system of spheres of influence by which powerful nations intervene in the affairs of others continues to the present day. It is often analyzed in terms ofsuperpower s,great power s, and/ormiddle power s.Post-Imperial China
In rare instances, multiple spheres of influence by different imperial powers were established in a single country as a compromise between the imperial powers and also when establishing a single sphere of influence is not feasible due to the size of that single country. For example, between the 1870s and the 1910s, although the Chinese Empire still existed as a sovereign country, it was divided into 6 SOI zones officially in which Russia took the area north of the
Great Wall , Germany theShandong Province, Japan theFujian Province, Britain theYangtze River basin, France the southwestern Chinese provinces borderingFrench Indochina and Britain/France jointly theGuangdong Province. Similarly, theOttoman Empire was divided by the imperial powers into several SOIs at around the same time.Empire of Japan
For example, during the height of its existence, the
Japanese Empire had quite a large sphere of influence, with the Japanese government influencing, or directly governing events inKorea ,Manchuria ,Vietnam ,Taiwan , and parts ofChina . The "Greater East Asia Co-Prosperity Sphere " could thus be quite easily drawn on a map of thePacific Ocean as a large "bubble" surrounding the islands of Japan and the Asian nations it controlledCold War
During the
Cold War ,Eastern Europe ,North Korea ,Cuba ,Vietnam , and, to a lesser extent (until theSino-Soviet split ) thePeople's Republic of China were said to lie under the sphere of influence of theSoviet Union . While, to a much lesser degreeWestern Europe ,Japan , andSouth Korea were often said to lie under the sphere of influence of theUnited States . For instance France and Great Britain were able to act independently to invade (withIsrael ) theSuez Canal , and France was able to withdraw from the military arm ofNATO ; such behavior would not have been tolerated under a true sphere of influence.Sometimes portions of a single country can fall into two distinct spheres of influence. In the colonial era the
buffer state s ofIran andThailand , lying between the empires of Britain/Russia and Britain/France respectively, were divided between the spheres of influence of the imperial powers. Likewise, afterWorld War II ,Germany was divided into four occupation zones, which later consolidated intoWest Germany andEast Germany , the former a member ofNATO and the latter a member of theWarsaw Pact .Australia
Australia n economic interests in neighboring island nations are reflected by rapid response to cases of military actions (including theIndonesian invasion of East Timor and subsequent changes in its political status), natural disasters (the2004 Indian Ocean earthquake ), political upheavals (with less success, the2006 Fijian coup d'état ), and conditional economic assistance. A predominantly Australian sphere of influence has been described forPapua New Guinea , theSolomon Islands ,Fiji , andEast Timor .New Zealand works closely with Australia in foreign policy and trade and has been described as a "junior partner" within this sphere of influence.

In
California "sphere of influence" has a legal meaning as a plan for the probable physical boundaries and service area of a local agency. Spheres of influence at California local agencies are regulated byLocal Agency Formation Commission s (LAFCO). Eachcounty in California has a LAFCO.Corporations
When talking in corporate terms, the sphere of influence of a business, organization or group can show its power and influence in the decisions of other business/organization/groups. It can be found using many factors, such as the size, the frequency of visits, etc. In most cases, a company described as "bigger" has a larger sphere of influence. For example, the software company
Microsoft has a large sphere of influence in the market ofoperating system s; any entity wishing for its software product to be successful must ensure that it is compatible with Microsoft's products. For another example, for companies wishing to make more profit, they must ensure they open their stores in the correct location. This is also true for shopping centers, who, to reap most profit, must be able to attract customers to its vicinity. There is no defined scale on how to measure the sphere of influence. However, the spheres of influence of two shopping centers, two business can. This can be done by measuring how far people are prepared to travel to the shopping center, how much time they spend in its vicinity, how often they visit, the order of goods available, etc.References
