This study analysised the condition of Xinjiang's petroleum resource and made an evaluation and it points out that the development of petroleum and natural gas of Xinjiang is still in the developing period in which it aims at discovering the petrol field and increasing its reserves.Although it has a great exploring potential,because of its geograghy limitation and a lack of exploring funds,the exploring level is till low,even lower than the everage level of the whole country. The study is based on theories of industry distributions,its concentration,macroscopic analysis,government regulations and continuing development.From microcosmic and macroscopic aspects,it scientifically and systematically analyses the problems in the development of petroleum industry in Xinjiang.It points that the developments of middle and upper reaches lack a balance and have no rational industry structures.So it is hard to form an integral industry chains.Moreover,the upper reach covers a too much large proportion in the development,so it can not give a strong impetus to other industries.Based it,the paper points the industrial concentration of Petroleum Chemical Products Manufacture of Xinjiang should be enhanced and Input to Petroleum Chemical Products Manufacture of Xinjiang should be increased.Due to a lack of an established fair and competitive market and government's perfect laws and regulations on petroleum industry,it points that the phenomenon of mixed operation has become common in monolopied business and competitive business,so the systems of petroleum industry needs to be restructured.It states clearly that the country should take the development and benefits of Xinjiang's economy into consideration when making strategies for petroleum development .Besides,the allocation of profits between the center and the local should be well arranged so that we can guarantee the profits of Xinjiang ,considered as a resource area.It also reveals that we should not only overcome limitations of resources,environment,economy and technology on continuring development,but also we should deal with some realistic problems well.For instance,contradictions between the concept of limited resource and continuing development,the relationship between petroleum industry's own features and continuing development,the contradictions between the limits on supply of petroleum and the need of future development of continuing resource ,outdated petroleum technology and the need of advanced technology for continuing development,tremendous damages to environment and requirements of environment protection for continuing development and Xinjiang continuing economic development,outdated policy of industry and continuing development,the relationship between continuing development of Xinjiang petroleum industry and continuing economic development of Xinjiang.
本研究以产业布局理论、产业集中度理论、灰关联分析理论、政府规制理论、可持续发展理论为依据,从微观、宏观两个层面,科学、系统、全面地分析新疆石油产业的发展问题,指出:新疆石油天然气目前仍处于油气田发现和增储的主要发展阶段,开发潜力巨大,但由于地质原因及勘探投入的不足,石油天然气探明程度偏低,低于全国平均水平;新疆石油产业产业结构布局不合理、上中下游发展不平衡,难以形成完整的产业链条,对工业的带动力与其本身具有的经济总量很不匹配;新疆石油开采业和石油加工业属于高度寡头垄断的市场类型,新疆石油化工业属于竞争型的市场结构,要想石油产业对新疆经济有较强的带动作用,新疆石油化工业必须上升到一定的层次和规模,在提高规模的基础上,提高新疆化工业的产业集中度;新疆石油加工业和化工业与农业呈现较高的关联度,加大对石油加工业和化工业的投入,对新疆经济的协调发展有着深远的影响;政府要从石油产业本质特征和发展趋势为着眼点,实施规制改革,分开政府规制政策的制定部门和监管部门职能,建立健全石油产业法律法规体系,对垄断性业务和竞争性业务实施分类规制;国家石油发展战略的制定应兼顾新疆区域经济的发展和利益,应切实处理好新疆与中央的利益分配,切实保证新疆作为资源产区合理的资源收益;新疆石油产业要想得以可持续发展,不仅要克服影响可持续发展的资源、环境、经济和技术等客观因素,还要处理好观念、需求、政策等诸多主观因素。
