我国制造业环境管制的实证研究
杜凯,
科技进步与对策 , 2007,
Abstract: 从制造业的角度出发,分析了政府对环境管制(ER)的两种形式:正式管制(FER)和非正式管制(I-ER),建立了环境管制均衡方程,并且采用面板数据的分析方法对理论假设进行了验证。研究表明,假设的影响制造业环境管制的主要因素:政府保护意愿、劳动密集程度、产业规模、经济外向度、产业国有化程度、科技吸收转化支出和劳动力素质的高低均产生了显著的影响。环境管制制造业环境管制正式管制非正式管制环境管制均衡方程面板数据分析

环境规制与雾霾脱钩效应——基于企业投资偏好的视角
王书斌,
中国工业经济 , 2015,
Abstract: 本文从企业投资偏好视角,分析了环境规制对工业发展与雾霾污染脱钩的作用机制,在验证不同环境规制能否通过影响企业投资偏好实现雾霾脱钩的基础上,通过门槛回归模型,分析当各种环境规制强度提高时,异质企业投资偏好与雾霾脱钩效应关系的变化情况。结果表明:环境行政管制仅通过企业技术投资偏好的路径实现雾霾脱钩,而环境污染监管和环境经济规制则通过企业技术投资偏好和类金融投资偏好两条路径实现雾霾脱钩。不同环境规制工具对企业投资偏好的雾霾脱钩效应影响不同,其中环境行政管制和环境污染监管强度的提高可增强企业投资偏好的雾霾脱钩效应,但环境经济规制强度的提高反而减弱企业投资偏好的雾霾脱钩效应。相比于总体样本,环境行政管制下大规模企业和地方国有企业技术投资偏好的雾霾脱钩效应较弱,这两类企业发生雾霾脱钩效应的环境污染监管门槛较高,而且在更高门槛下,类金融投资偏好不存在雾霾脱钩效应,表明大规模企业在更高环境经济规制下可能存在脱离实体经济的现象。
能源消费、贸易开放与经济增长

财贸经济 , 2014,
Abstract: 本文采用中国1995-2012年省际面板数据,运用加工贸易额对贸易开放度进行修正,引入一步SYS-GMM动态面板模型,考察了中国能源消费、贸易开放与经济增长之间的相关关系和地区差异性。研究发现:能源消费和贸易开放对中国的经济增长存在显著的促进作用;在扣除了加工贸易量进行修正后,贸易开放对中国经济增长的促进作用进一步提升;贸易开放与能源消费交叉项对中国经济增长具有负向作用,即贸易开放通过提高能源利用效率从而间接地制约了能源消费对中国经济增长的贡献率;能源消费和贸易开放对经济增长的影响在中国东中西部之间存在显著的地区差异性,具体而言,能源消费对东中西部地区的经济增长具有显著的促进作用,但是贸易开放对东部地区的经济增长具有显著的促进作用,而在中西部地区的促进作用却不显著。最后,本文根据以上研究结论提出了若干对策建议。
内蒙古经济增长与资源优势的关系——基于“资源诅咒”假说的实证分析

资源科学 , 2010,
Abstract: 本文从“资源诅咒”假说出发,对内蒙古地区的资源优势与经济增长之间的关系进行了计量检验和分析,并给出了相应的政策启示。结果表明:从长期来看,内蒙古的确存在着“资源诅咒”现象,主要原因是资源开发导致的“荷兰病”效应。但西部大开发以后,随着国家及地区各项政策的实施,“资源诅咒”现象在内蒙古地区被破解。通过进一步实证分析,本文发现该地区破解“资源诅咒”的主要原因是该地区制造业部门全要素生产率(TFP)的提升,使得经济增长呈现出可持续性,但随着近年来该地区能源开发强度的增大,制度弱化的趋势日益呈现。
碳税与区域经济协调发展——基于分位数回归的实证研究

Abstract: 摘要 以碳税的征收如何最大限度地兼顾区域经济协调发展为出发点,通过分位数回归方法,考察了开征碳税对全国及东中西和东北四大区域经济协调发展的影响效应。结果表明:就全国而言,征收碳税将显著地降低区域经济协调发展水平,且其影响效应在条件分布的不同位置存在明显的差异性。扩大人力资本规模、促进区域贸易往来能够削弱开征碳税对区域经济协调发展的负面影响;开征碳税对东部和东北地区的经济协调发展存在负面影响,且在东北地区的负面影响最为明显,而对中部和西部地区的作用效果则恰好相反。据此,从实施阶段性、差异化碳税税率等角度提出对策建议。
Abstract:The effect of introducing carbon tax on the coordinated development of national and regional economy was explored by applying the quantile regression approach for the purpose of maximizing its positive impact. The results indicated that: as to China in the whole, introducing carbon tax has a significantly negative effect on promoting the level of coordinated development of regional economy, but enhancing human capital scale and reinforcing regional trading could alleviate the negative effect; as to the four regions, introducing carbon tax has a significantly negative effect on promoting the level of coordinated development of regional economy in the eastern and northeastern regions, and the negative effect in the northeastern region is much more serious, whereas introducing carbon tax shows a positive effect in the central and western regions. Finally, some relevant policies and suggestions like carrying out periodical and differentiated carbon tax were proposed based on the results.
我国产业发展的低端锁定困境与破解路径——基于矫正城镇化扭曲视角的实证分析

Abstract: 经济发展与社会结构变迁之间的矛盾运动关系表明,扭曲的城镇化发展模式是造成我国产业发展低端锁定的重要的社会结构原因。文章将我国的产业发展低端锁定问题拓展至工业化弱质和服务业滞后两个部门,将城镇化扭曲投影到城镇化建设的动因扭曲、主体扭曲和功能扭曲三个维度,构建“两部门?三维度”分析框架,采用典型化事实与评价指标体系相结合的方法分析了我国产业发展低端锁定的困境,并构建PLS-SEM结构方程模型,实证探讨了矫正城镇化扭曲,实现我国产业发展低端解锁的路径选择。研究结论表明,我国的工业化弱质问题表现为结构演进受阻和效率提升缓慢,我国的服务业滞后问题表现为生产性服务业的配套生产能力和生活性服务业的保障消费能力不足。改善地方财税制度可以显著地降低土地城镇化水平,加强对农民工劳动技能和素质的培养可以显著地降低农民工城镇化水平,在供给侧提升基本公共服务供给水平可以显著地降低城市病水平,进而矫正我国城镇化建设的动因扭曲、主体扭曲和功能扭曲。矫正城镇化扭曲对于改善我国工业化弱质和服务业滞后问题具有显著的促进作用,可以推动我国产业发展的低端解锁。
中国三次产业生产用水消耗的时空演绎分解 ――基于LMDI-I模型的经验分析
Spatial-temporal Deductive Dissolution of Productive Water Consumption in Three Industries of China ―Empirical Analysis Based on LMDI-I Model

Abstract: 本文借鉴Kaya恒等式,并应用LMDI-I分解模型,分析驱动中国2003-2014年三大产业生产用水消耗的人口效应、经济水平效应和用水效率效应的时空演绎特征。研究发现,人口效应是抑制第一产业和促进第二产业以及第三产业生产用水消耗的主要因素之一,同时经济水平效应对三大产业生产用水消耗主要表现为正向促进效应,而用水效率效应则主要表现为负向抑制效应。每个省区的从业人员变动、经济水平变动和用水效率变动共同决定了全国生产用水消耗的变动,在当前特定情况下,地区生产用水消耗的下降与全国生产用水消耗下降存在不一致性,因此,为了顺利实现全国水资源节约的整体目标,需要及时评估各省区对全国水资源节约的贡献度,准确把握中国生产用水消耗的空间分布特征,重点关注那些对生产用水消耗影响较为关键的省区,以尽快实现对水资源消耗总量的有效控制。
The Relationship between Economic Development Mode and Natural Resource Advantages in Inner Mongolia: An Empirical Analysis Based on the Resource Curse Hypothesis
内蒙古经济增长与资源优势的关系——基于“资源诅咒”假说的实证分析

XU Yingzhi,HU Yongshun,

资源科学 , 2010,
Abstract: The annual economic growth rate of Inner Mongolia Autonomous Region ranked first from 2002 to 2007. In the meantime, it maintains remarkable natural resource advantages nationwide. This has prompted people to think whether Inner Mongolia has obviated the resource curse, and whether the development mode can shed light on the economic development across western regions of China. In addition, it is meaningful to investigate if the high growth rate of economy is due to the rising of energy price, or to the mechanisms of economic growth itself, and if the Dutch disease exists in Inner Mongolia for the rapid investment on resource-based industries in that the Dutch disease is generally applicable to areas with rapid growth of the primary product. Based on the resource curse hypothesis, the authors carried out an empirical analysis on the relationship between economic growth and natural resource advantages in Inner Mongolia in the context of its high-speed economic development and an abundance of natural resources. Economic development of Inner Mongolia over the period 1987-2007 was comprehensively explored. Results revealed that in the long-term economic development, the resource curse hypothesis still exists in Inner Mongolia. An increased intensity of resources exploitation showed a negative effect on the economic growth due primarily to the Dutch disease. On the other hand, technological progress played an active role in the economic growth. When considering the periods 1990-1999 and 2000-2007 respectively, we suggested that the resource curse existed in Inner Mongolia during the period 1990-1999. Nevertheless, after the implementation of the western development strategy, the resource curse was greatly weakened over the period 2000-2007 when the role of development of the manufacturing sector positively contributed to the economic growth. It was also found that during the period 2000-2007, the weakness of institution was gradually emerging combined with intensifying energy development. The effect of technological progress on the economic development appeared to be immaterial as other studies had suggested in Inner Mongolia. The reason for circumventing the resource curse in Inner Mongolia could be ascribed to the enhancement of the total factor productivity (TFP) of the manufacturing sector. The main reason for the growth of TFP was the government increasing investments in the manufacturing sector in Inner Mongolia given its ability of sustainable development. Some policy recommendations are given on the economic development of Inner Mongolia in the context of the resource curse.
STUDY ON AQUATICD OFF FLAVORS IN EUTROPHIC DONGHU LAKE
东湖富营养水体中藻菌异味性次生代谢产物的研究

XU Ying,

生态学报 , 1999,
Abstract: The Donghu Lake,in Hube Province,is selected as a typical eutrophic water for the study.The off flavor compounds from different locations monthly were indentified and monitored in the years from 1995 to 1996.Meanwhile,the species and biomasses for algae and bacteria were identified and counted.It was found that the principal compound producing earthy musty odors in the Donghu Lake was 2 methylisobornel (MIB),which came from the secondary metabolites of P.tenue and Actinomycets. There were three apex periods for MIB occurrences,i,e.January,April and September.Furthermore,their concentrations were directly proportional to the eutrophication levels and the biomasses of P.tenue and Actinomycets.
