Abstract: In recent years, the competition in agricultural machinery industry has become increasingly fierce, and the living environment of agricultural machinery manufacturing enterprises is not optimistic. In order to improve the market competition level of M agricultural machinery manufacturing enterprises,  the evaluation system of the core competitiveness of agricultural machinery manufacturing enterprises from the perspective of their own characteristics and the impact of supply chain is constructed from the perspective of supply chain, and the comprehensive weighting method combining analytic hierarchy process and CRITIC method is introduced.The evaluation model of core competitiveness of agricultural machinery manufacturing enterprises is established by means of matter-element extension evaluation method. Taking M agricultural machinery manufacturing enterprise in Xinjiang agricultural machinery supply chain as the research object, the comprehensive correlation degree of its core competitiveness level is calculated. The results show that the core competitiveness of M agricultural machinery manufacturing enterprises is in the excellent level, but 17.8% of the indicators are still in the general level. Finally, the extension innovation method is used to improve it. The research shows that the established evaluation model and the extension innovation method can effectively judge and improve the core competitiveness of M agricultural machinery manufacturingenterprises.

Key words: core competitiveness, agricultural machinery manufacturing enterprises, supply chain, matter element extension method, analytic hierarchy process, extension innovation method

摘要： 近年来农机行业竞争日益加剧，农机制造企业生存环境不容乐观，为提高M农机制造企业市场竞争水平，从农机制造企业自身特性和供应链影响等角度，构建供应链视角下的农机制造企业核心竞争力评价体系，引入层次分析法和CRITIC法相结合的综合赋权法，结合物元可拓评价法建立农机制造企业核心竞争力评价模型。以新疆农机供应链上M农机制造企业为研究对象，计算其核心竞争力等级的综合关联度。结果表明，M农机制造企业的核心竞争力处于优秀等级但仍然有17.8%的指标处于一般的等级，最后采用可拓创新方法进行改善。研究表明，建立的评价模型和采用的可拓创新方法可以有效判断和提升M农机制造企业核心竞争力水平。
