Regional economics has shared many traditions with regional science, whose earlier development was propelled by Walter Isard and some economists' dissatisfaction with the existing regional economic analysis. Despite such a rather critical view of regional economics, however, it is hard to be denied that the "economic" approach to regional problems was and has been the most significant one throughout the development of regional science. As a sub-discipline of economics, it has also developed its independent traditions and approaches that conform with the subject matter or perspective of economics. The information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
