How can China's rural governance and agricultural production development embrace the "Internet Plus" development mode? How will the emergence of new business forms help China's rural areas contribute to the development of China's economy? In response to these questions, Chen Jing, director of Research Center for Technology Innovation and professor at School of Economics and Management of Tsinghua University, pointed out in the latest W.E. Talk that cyber governance will greatly improve the social effectiveness of rural governance, attracting more entities to join the governance process.
He further added that by empowering agricultural production, e-commerce and rural tourism, internet technologies will help the rural economy achieve better development. (Xue Lingqiao)

连云港市住建局工程质量安全监管处负责人表示，江苏明确发文不让用镍砂的就两个地方西岛隆弘女友，淮安市淮阴区和徐州市，其他地方没有明确发文。虽然连云港去年也发文了，但是因为已经用了很长时间了，不能因为发文就直接不让用了，“不能一禁了之，所以我们发文叫审慎使用。镍渣做成机制砂，如果处理不好的话会有问题，镍渣本身粗不能作为细骨料用就需要粉碎，第二原始的镍渣可能含铁，含铁就会给工程带来影响，所以处理过程中需要磁选。”
“假如重金属含量比较高的话，我也不建议用，按照标准方法短时间测出来的结果，重金属浸出量不多或者浓度比较低。但是从另一个方面来讲，它一直在不断浸出，国内没有严格禁止镍砂的规定，国外有些国家明确规定不锈钢的渣子就不能用，你是什么过程出来的你就不能用。”亚洲混凝土联合会主席、湖南大学土木工程学院教授史才军介绍。
