自主研发、技术引进与能源强度——基于中国地区工业的实证分析

本文采用2005-2007年中国30个地区工业面板数据,将地区工业的研发总支出划分为自主研发、国外技术引进和国内技术转移三个部分,在估算自主研发存量和技术引进存量的基础上,实证检验了自主研发、技术引进对地区工业能源消耗强度的影响。研究表明,自主研发、技术引进对地区工业能源强度的影响存在差异：自主研发对工业能源强度有显著负效应;国外技术引进对工业能源强度有显著正效应;国内技术购买对工业能源强度没有显著影响。研究还发现,国内技术购买并没有通过R＆D途径促进地区工业能源强度的下降。     

河南省国内旅游客源市场时空结构分析

国内旅游已经成为我国越来越多居民生活方式的选择。通过相关资料,分析了近10年来河南省国内旅游客源市场时空结构特征。结果表明,近10年来河南省国内旅游客源增长速度较快,总量较大,国内游客分布存在地域不平衡的现象,但这种差异在逐渐较小;河南省省内游客流量一直大于省外游客流量;河南省国内游客主要流向旅游经济发展比较好的地市和经济比较发达的地区以及河南周边地区如陕西、湖北和经济发达地区如江浙、广东等地。     

絮凝法处理木薯淀粉生产废水试验研究

木薯淀粉生产加工过程中所产生的生产废水给环境造成了很大的污染。对木薯淀粉生产废水进行了絮凝试验研究。试验分别采用了3种絮凝剂:聚合硫酸铁、聚合氯化铝、精制硫酸铝,助凝剂采用聚丙烯酰胺。通过对试验数据进行分析得出,处理木薯淀粉生产废水的最佳条件是:pH值为7.5,采用聚合氯化铝作絮凝剂,聚丙烯酰胺为助凝剂,处理每吨废水需花费0.14元。     

How a Firm's Domestic Footprint and Domestic Environmental Uncertainties Jointly Shape Added Cultural Distances: The Roles of Resource Dependence and Headquarters Attention

Even though many firms conduct most of their business domestically, international management research has remained remarkably silent on the role of a firm's domestic footprint in its internationalization strategy. We shed light on that role by exploring how the size of a firm's domestic footprint influences the cultural distance that the firm adds to its country portfolio when expanding internationally. Integrating resource dependence theory and the attention‐based view, we hypothesize that a firm's domestic footprint has a negative relationship with added cultural distance (ACD), and that domestic policy uncertainty strengthens this relationship whereas domestic demand uncertainty weakens it. We find robust support for our hypotheses in a sample of the world's largest retailers covering the period 2000–07, indicating that a firm's domestic footprint and domestic environmental uncertainties jointly shape cross‐cultural expansion strategies. Our findings suggest that ACDs reflect headquarters executives' desire to avoid ineffective foreign expansions, hinting at possible biases in studies of the performance effects of distance.     

外商直接投资对国内投资影响的实证分析

以1993—2007年常州市FDI、国内投资以及GDP的时间序列数据为基础,利用Panel Data模型,对常州市FDI对国内投资的挤入挤出效应进行计量分析,结果表明常州市FDI对国内投资的影响表现为挤出效应。     

靖江市污染源普查现状分析及污染控制措施

江苏省靖江市作为长江三角洲经济区的组成部分,在综合实力快速攀升的同时,造成的环境污染也不可小觑。利用污染源普查数据和社会经济统计数据,对本区域内的污染物产生、排放特点及污染现状进行了分析,指出了在工业污染得到重视的同时,生活污染和农业污染也不可忽视。它们共同作用,造成环境质量水、气、土壤(底质)中多项指标超标。并针对工业污染、生活污染和农业污染的不同排放特征提出相应的治理措施。     

青岛高端产业发展水平国内外对比分析

基于国家统计局、青岛市统计局、世界知识竞争力指数等数据,采用层次指标分析、聚类分析等方法,分析了青岛与国内19个城市的高端产业发展水平的差异,绘制了全球138个城市或地区的高端产业人力资源分布,并研究了青岛高端产业的绩效情况。结果显示,青岛高端产业具有较高生产率及较高增加率的特点,但与国内外先进城市相比,尚处于弱势位置,整体发展水平仍存在不小差距。     

关于实现内外贸一体化的障碍和对策思考

在中国流通领域,内外贸一体化改革在体制上、机制上、政策法规上、观念上、管理上等存在着诸多障碍。要加快内外贸一体化进程,必须深化流通体制的改革,促进内外贸市场的互补,加快流通业的法制建设,培育跨国公司,加强中介组织的建设,建成统一的内外市场,以提高中国经济的整体实力。     

China's agriculture,smallholders and trade: driven by the livestock revolution?*

China's sustained rapid economic growth and development has contributed to the surge in consumption and production of livestock in that country  termed the livestock revolution. Consumption trends are first reviewed, and changes in food consumption patterns include a marked shift away from grains and towards meats and dairy products. A question is to what extent this rapid increase in demand for livestock products is reflected in China's agri‐food trade statistics? While her agri‐food imports have dramatically increased since China's accession to the WTO, livestock products have not made a noticeable contribution, although the import of certain animal feedstuffs has. This implies China's continuing self‐sufficiency in most livestock products. The paper next considers developments in China's livestock farming sector and policies that have been contributing to these supply‐side developments. The paper concludes with an examination of issues that may be important to the future development of China's, and the world's, livestock situation;  this includes future demand developments, and the question of whether future demand growth in China might be met with local production, imports of final product, and/or imports of feedstuffs.     

培育新的消费热点 大力发展国内旅游

影响旅游需求的客观因素主要是收入和闲暇时间,主观因素主要是旅游动机。我国旅游业经过改革开放以来20年的发展,形成了相当规模的产业基础,需求条件和供给条件逐步成熟,因而国内旅游业在未来应该可以获得更大的发展,这既是提高旅游资源和旅游资本的边际效益的有效途径,也是提高人民生活质量的现实需要,它有利于稳固和提高旅游的产业地位,是促进经济发展和结构调整、扩大国内需求的有效措施。
