【摘要】：我国的快递业起源于上个世纪80年代初，当时主要由中国邮政垄断经营，在改革开放初期发展较为缓慢。到了90年代，一批民营快递企业如雨后春笋般发展，近几年由于电子商务的带动，快递产业飞速发展。时至今日，我国已经形成了一个由国营、民营快递企业共同主导的国内快递市场，市场结构逐步完善。在社会主义市场经济的大浪淘沙下，我国的快递市场形成了同时由国有企业和民营企业共同竞争的混合寡占市场。国营快递企业以社会总福利或总成本为主要目标，而民营快递公司以最大化自身利润为主要目的。针对快递市场中国营企业与民营公司共存且行为分歧这一特征，本论文假设国营企业与民营公司分别同时选择服务费率与服务容量投资规模，分别建立混合寡占竞争模型和市场竞争模型。前者描述国营企业最大化总的社会福利或者总社会成本，民营公司最大化自身利益，而后者描述国营企业和民营公司均各自最大化自身利益。本文得出，若国营企业与民营企业提供服务的技术条件完全对称，则无论国营企业选择福利最大化为目标或利润最大化为目标，社会总福利均不变；当技术条件不对称时，若国营企业效率高于民营企业，则国营企业以福利最大化为目标能使社会福利达到最大，，然而，若国营企业效率低于民营企业，则国营企业应以最大化自身利益为目标。
[Abstract]:China's express delivery industry originated at the beginning of -20s, when it was mainly operated by the Chinese postal monopoly and developed slowly in the early stage of reform and opening up. In 90s, a group of private express delivery enterprises sprang up like bamboo shoots. In recent years, with the development of electronic commerce, express delivery industry has developed rapidly. Up to now, China has formed a domestic express delivery market, which is jointly dominated by state-owned and private express delivery enterprises. Under the background of the socialist market economy, the express delivery market of our country has formed a mixed oligopoly market in which the state-owned enterprises and the private enterprises compete together at the same time. The main goal of the state-owned express delivery enterprises is the total social welfare or the total cost, while the private express companies aim at maximizing their own profits. In the express market, the state-owned enterprises coexist with the private companies and the behavior is different. This thesis assumes that both state-owned enterprises and private companies choose the scale of investment of service rate and service capacity respectively. The former describes the state enterprises to maximize the total social welfare or total social costs, private companies maximize their own interests. The latter describes that both state-owned enterprises and private companies maximize their own interests. This paper concludes that if the technical conditions of services provided by state-owned enterprises and private enterprises are completely symmetrical, No matter the state-owned enterprise chooses the welfare maximization as the goal or the profit maximization as the goal, the total social welfare will remain unchanged; when the technical conditions are not symmetrical, if the efficiency of the state-owned enterprise is higher than that of the private enterprise, However, if the efficiency of state-owned enterprises is lower than that of private enterprises, the goal of state-owned enterprises should be to maximize their own interests.
