Change in distribution environment has brought about many structural changes such as extension and monopoly of corporate distribution businesses after the opening of distribution. There are conflicting opinions on the effect of discount stores' growth on consumer prices through the structural changes, fortunately which are well shown in the preceding studies.
Discount stores growth of these structural changes has emerged early and contribute directly to price stability through competition with other Category stabilizing inflation entire Wal-Mart effect. Previous studies look at the effects of Wal-Mart due to price drops in the presence of some items that uncovered the presence of the materials studied the effects of Wal-Mart. , However, focused on the world's largest distribution company, to analyze the effects of Wal-Mart Wal-Mart entry that is causing the negative economic, social, according to results of a study side view of that study was Divide opinion through structural changes in the Wal-Mart effect, which is well in domestic and overseas study are shown.
Thus complementing the limitations of these preceding studies, this study purposes to analyze empirically prices the growth of discount stores' ripple effect on national economy, that is, direct/indirect impact on prices, to draw out implications and to suggest policy plans according to that. In addition, I carried out this research with the purpose of suggesting directions for the development of distribution industry, it examines Wal-mart effect, that is, the growth of discount stores on economy and society.
This study to test the effects of Wal-Mart has grown to large supermarkets and hypermarkets to target growth in inflation, which is based on macro-economic study is Therefore, this research literature on the internet and Census Bureau, through the Bank of Korea data for research topics with the data collected through the existing literature, previous studies were Through previous research and theoretical background, a set of hypotheses to test the hypothesis, and data were collected. The data collected statistics program 'Excel 2005' by the statistical processing and clean-up program 'SPSS 15.0', 'EViews 5.0', using the time series data and analysis of the stability test was carried out.
The growth of large retail stores in Wal-Mart effect on prices in order to analyze the impact of a proper analysis of time series analysis methods are judged. For this reason, time series analysis of the methods in this study the stability of time-series data by test vector error correction model (Vector Error Correction Model: VECM) was carried out.
In this study Hypothesis is that ‘discount store growth affects consumer prices index.’ As a result of the test of hypotheses, Wal-mart effect that discount store growth affects consumer prices has the increase effect of consumers prices index partially. However, it turned out that the seasonal adjustment index of the amount of sale of supermarket and special goods retailers partially drops the consumer prices index.
As a result of indirect effect analysis, the effect of seasonal adjustment index of discount store sale amount on consumer prices index turned not to be statistically significant.
To examine implications and plans for policy development drawn out by the result of the analysis: first, discount stores should be able to contribute to revitalization of local economy seeking for plans to purchase preferentially local products increase the weight of purchase; second, discount stores should attempt to stabilize consumer prices through rationalization of management; third, they should be able to contribute to the increase of the total employment rate deliberating plans to treat preferentially graduates from colleges in the areas with store; and fourth, discount stores should expand partnership with middle and small distribution firms.
