使用2002-2013年的工业企业数据和进出口贸易数据,重点估计了国际分工及结构转型对就业和收入的影响作用。结果表明,初级加工品分工和设备零部件分工对就业扩张和收入增长均产生正向影响,由设备零部件分工占比上升构成的国际分工结构转型能够产生就业质量效应和收入提升效应。生产率、技术进步和价值链是国际分工结构转型影响劳动力市场就业结构和收入分配的关键因素。国际分工结构转型引起的就业质量效应和收入提升效应均呈现先上升后下降的趋势,并且最终平稳到较低的正常范围,就业质量效应和收入提升效应分别在滞后5期和滞后7期最为突出。研究意味着我国企业想要通过升级国际分工结构层次继而推动就业质量和收入水平的提升,就需要不断扩大在设备零部件国际分工方面的增量影响,还要加强对设备零部件国际分工所含知识产权和科技专利溢出效应的学习吸收能力,以及提高外部知识专利与内部研发技术相结合的创新水准。

在信息化时代,产业的互联网应用已经成为实现制造业高质量发展的重要途径之一。本文利用2010—2022年地级及以上城市面板数据,结合上市公司数据,探讨了互联网发展对企业市场竞争力的影响。研究表明:互联网促进企业市场竞争力提升。在影响机制方面,互联网通过促进生产率提升、技术创新、产业结构升级、收入和规模效应、高级要素流动推动企业市场竞争力增强;互联网对企业市场竞争力提升作用在中小城市更加明显,这主要是由于互联网的知识技术空间外溢效应发挥了作用。未来应大力推动互联网基础设施建设投入,促进互联网与传统产业融合发展,加强互联网关键核心技术的研发支持。

随着全球生产分工体系的进一步发展,中国参与国际化承接外包和对外发包生产方式的程度和规模呈不断膨胀趋势,这种趋势还伴随着价值链水平的提升而加强,本文着重探讨了承接外包和对外发包对中国工业行业价值链影响的差异性。研究结论表明:承接加工品、零配件和资本品工序外包对价值链的提升具有正向影响,并且这种正向影响较为稳定且逐渐增强;承接消费品工序外包对价值链的提升效应难以确定;材料发包比率的提高会降低行业的价值链水平,平均工序环节外包对价值链的正向影响会随着材料发包的提高而削弱;服务发包比率的提高会增加行业价值链的水平,平均工序环节外包对价值链的正向影响会随着服务发包的提高而增强。

An anaerobic/oxic membrane bioreactor (A/O MBR) was used for treatment of dyeing wastewater from a woolen mill. COD and color of the wastewater were 54—473 mg/L and 40—400 dilution time (DT) respectively. The ratio of boD 5/COD was less than 0.13. By the A/O MBR process, the average removal of COD, boD 5, color and turbidity was 82%, 96%, 71% and 99%, respectively. The average COD, boD 5, color and turbidity of effluent was 37 mg/L, 0.8 mg/L, 40 DT and 0.44 NUT respectively. The effluent COD met the local standard of reuse water in Beijing, China. The average COD volume load of the anaerobic biological tank was 0.0483 kgCOD/(m 3·d) and that of the aeration tank of the MBR was 0.3589 kgCOD/(m 3·d). The sludge load of the MBR was 0.19 kgCOD/(kg·MLSS·d) on average and the maximum of that was 0.4 kgCOD/(kg·MLSS·d). The flux of the A/O membrane bioreactor could be remained at larger than 50 L/(h·m 2·0.1MPa). The results indicated that A/O membrane bioreactor has technical feasibility for treatment of woolen mill wastewater.
