However, development of cement industry will also face disadvantageous factors: 1 along with the coming of high cost epoch, continued rising in costs of coal, power, mineral resources, environment, human resource and capitals and the increase in social responsibilities that enterprises should take on will bring restricting factors to the investment and development of cement industry; 2 on the basis of the gradual increase of industrial concentration, market competition will change from the current competition between large enterprises and small enterprises and between new dry process and backward shaft kiln technology to the competition among large enterprises and among new dry processes, so the extent of market competition may further extend; 3 along with RMB increasing in value, demand decreasing in north America, new production lines in Middle east being put into operation and the persistent high price of international shipping, national cement export will face huge menace; backward flow of export products will certainly aggravate market competition in some areas.

但水泥行业的发展也将面临不利因素。一是随着高成本时代的到来，煤炭、电力、矿产资源、环境、人力、资金等成本的不断提高及企业所承担的社会责任的增加，将对水泥工业的投资和发展平添抑制因素；二是在产业集中度逐步提高的基础上，市场的竞争将由目前大企业与小企业、新型干法与落后立窑工艺之间的竞争转为大企业与大企业、新型干法与新型干法之间的竞争，市场竞争的程度有进一步加大的可能；三是随着人民币的升值、北美市场需求的下降、中东新生产线的投产及国际航运价格的居高不下，我国水泥出口将面临巨大的威胁，出口产品的回流，势必将加剧局部地区的市场竞争。
