根据预测，2015年国内工程机械销售规模将达到9000亿元，主机产品国际需求量将达到2100亿美金，中国工程机械产品出口将达到260亿美金，成为世界出口大国。工程机械经历了2011年的动荡发展，在2012年将进入缓慢发展期，据预测，在2012年，工程机械行业会增长12％，但是这增长从何而来，我国工程机械行业在这一年到底是该怎么发展？
绿色环保仍是主流工程机械行业发展从粗放型、模仿型、数量型向科技创新型、质量效益型、美观环保型转变。工程机械行业“十二五”科技发展目标是以科技先行，重点围绕低碳、绿色、高效、节能、信息化工程全面展开。而节能、降耗、减排的发展目标实现一方面是通过产品结构优化与轻量化设计、减低尾气排放；另一方面改造传统制造工艺，提高专业化生产规模，在生产过程中采用节能、环保、低碳工艺设备进行产品制造。因而在2012年，工程机械行业进行节能、环保、低碳涂装技术应用势在必行。
零部件发展势在必行我国虽已成为工程机械大国，但是为其配套的基础关键机械零部件依然受制于人的局面并未改变，液压马达、泵、阀等关键机械零部件，70％以上依靠进口！机械零部件是工程机械产品发展重中之重，当工程机械发展到一定阶段，就会面临技术壁垒，而技术壁垒的关键问题就是核心机械零部件的发展与生产，只有能拥有核心机械零部件的生产能力，才能提高企业的竞争力，才会在工程机械市场有话语权！我国工程机械企业要做的就是要打破国外对机械零部件市场的垄断，创造出属于自己的机械零部件市场。
租赁市场逐渐火起随着我国大规模基础设施投资的持续，为中国工程机械租赁行业带来了绝佳的市场机遇。据统计，我国建筑行业每年超过23％的复合增长率及国家40000亿元投资的后期效应，使工程机械租赁市场的总额超过3000亿元人民币。国内施工企业使用设备观念的转变使得设备租赁的渗透率逐步提高，从而也为设备租赁业带来了新的市场机遇。
持续发力海外市场2011年，中国工程机械业的营业收入同比增长17％，达5000亿元左右，出口额更是突破150亿美元，创历史最高水平。但目前国内工程机械企业的国际化程度并不高。2011年上半年，徐工机械海外收入占总销售额的13.9％，柳工为9％，中联重科为4.2％，三一重工为3.89％。目前国内工程机械巨头无不将“海外扩张”视为核心战略。从备受瞩目的中联重科收购CIFA，到三一重工收购普茨迈斯特；从徐工另辟蹊径加速收购海外研发机构，到柳工“安营扎寨”80国，无不显示出本土企业与国际品牌同台竞技的决心。
2012是我国工程机械持续发力、不断变革的一年，相信行业经过2012年不断发展，我国不但是工程机械出产大国，而且是工程机械科技大国！
