Decreasing Concentration and Reversibility of the Resource Partitioning Process: Supply Shortages and Deregulation in the Bulgarian Newspaper Industry, 1987-1992
研究了1987-1992年保加利亚报业在资源短缺和放松管制下，行业集中度下降如何影响组织多样性和企业定位策略，发现资源分割过程是可逆的，且集中度下降掩盖了子行业集中度上升，形成多中心资源空间。
This paper examines the effect of decreasing industry concentration on organizational diversity and on the choice of positional strategies in the population of Bulgarian newspaper enterprises between 1987 and 1992. The results of the exit rate analysis of specialist organizations in a period of resource depletion confirm the reversibility of the resource partitioning process. In the case of post-socialist foundings spurred by deregulation, decreasing overall industry concentration is interpreted to conceal increasing concentration at the sub-industry level and points to the emergence of a second market centre. The formation of such polycentrist resource space accounts for the unexpected effect of overall diminishing industry concentration, which deters the entry of generalists and favours the start-up of specialists.
