摘要:

垂直并购不仅要考虑价格的协调,还要考虑质量的协调以及质量与价格的协调。本文将一体化企业、中间品供应商以及下游生产商等多种类型厂商引入Salop模型,分析垂直并购对产品定价、产品质量以及社会福利的影响。研究发现,在一体化企业不参与中间品供给的情形下,市场中的垂直并购会提升并购企业的最终产品质量与定价,但是会降低非并购企业的产品质量与定价。从行业整体看,垂直并购行为会带来市场产品平均质量以及定价水平的下降。如果消费者对产品质量重视程度足够高(低),垂直并购会损害(提升)消费者剩余,进而带来整体社会福利水平的下降(上升)。本文进一步分析了一体化企业参与中间品供给的情形,发现上游企业与下游企业的垂直并购会带来平均产品质量水平的提升;而一体化企业与下游企业的并购则会导致平均产品质量水平的下降。

Abstract:

In order to reduce costs and optimize the allocation of resources, vertical merger and acquisition has become an important mode of capital operation and business location. Vertical mergers and acquisitions should not only consider price coordination, but also quality coordination and quality and price coordination. How does a firm's vertical merger affect the product quality and price of the acquiring and non-acquiring firms? Will such mergers and acquisitions improve social welfare?Various types of manufacturers such as integrated enterprises, intermediate suppliers and downstream manufacturers are introduced into the Salop model, and the impact of vertical mergers and acquisitions on product pricing, product quality and social welfare is analyzed by constructing a multi-stage game model. It is found that the integration of firm is not participate in the case of intermediate goods supply, the vertical mergers and acquisitions in the market can improve the quality of the final product of M&A and pricing, but reduces the M&A enterprise product quality and pricing. Look from the industry as a whole, vertical merger behavior leads to market products, on average, a decrease in the level of quality and pricing. If consumers attach high (low) enough importance to product quality, vertical M&A will damage (improve) consumer surplus, which will lead to a decline (rise) in the overall social welfare level. The situation is analyzed that integrated firms participate in the supply of intermediate goods, and it is found that vertical M&A between upstream firms and downstream firms will lead to the improvement of average product quality. And the integration of enterprises and the downstream enterprises mergers and acquisitions is to cause a decline in the average level of product quality. The results of this study have important reference value for government censorship enterprise vertical mergers and acquisitions.

Key words: vertical merger, product quality, pricing decision, social welfare, salop model
