国际贸易对环境的影响:中国各省的二氧化硫(SO2)工业排放

为了更好地理解贸易对环境的影响,我们建立了一个四方程联立系统,其中SO2排放由规模、结构、技术这三个经济因素决定,并直接由贸易影响。然后我们利用中国29个省份1993—2001年期间工业SO2排放的面板数据来估计模型。我们的估计结果显示,出口和制造品进口在工业SO2排放的决定中起了完全相反的作用。结果不支持污染庇护地假说;出口企业所面对的市场竞争增强,是促进污染治理技术进步的积极因素。     

浙江工业产品贸易的“污染足迹”研究

改革开放以来,浙江省的贸易保持着快速的增长。工业产品作为浙江省对外贸易的绝对主体,每年巨大的贸易顺差,必然给浙江省带来很大的污染成本。文章从＂污染足迹＂的概念出发,利用浙江省各工业部门的对外贸易量及污染物的排放数据进行定量分析,核算出浙江省具有代表性的产业部门的产污系数,进出口污染系数及部门来源。结果表明：浙江省工业产品的对外贸易虽然向海外转移了污染物,但是总体来说,巨大的贸易逆差在浙江省留下了污染足迹核算和分析的结果表明,从1997年到2006年,浙江工业产品出口正慢慢偏向于低污染行业,进口偏向于污染密集型行业;浙江省工业产品出口带来的废水的增长速度最快,而废气和固体废弃物呈缓慢增长趋势;化学工业的进口转移了最多的污染物,而金属采选业的进口转移了最多的固体废气物。     

生产分工视角的中国对美国货物出口竞争力验证

考虑生产分工对中美间经贸联系程度、贸易规模和结构的影响,基于生产分工下价值链视角,构建出口竞争力测度指标体系,验证中国对美国货物出口竞争力。结果显示:2016年及之前,中国仅在杂项制品大类上,对美国显示出较强出口竞争力,机械和运输设备、动物和植物油、油脂和蜡我国具有比较优势,化学成品及有关产品、按原料分类的制成品双方竞争性较强,其余大类上,中国对美国出口竞争力不具优势。引入其他国家作对比的分析结果表明:中国对对比国家均无显著出口竞争力,而且对美国出口具有单价优势的资本技术密集型产品,对这些国家出口多缺乏单价优势,而2017年以来对美国和对比国家的贸易变化,进一步勾画出中国对美国货物出口竞争力不足。在生产分工主导全球产业发展背景下,提升我国在全球生产分工中的参与地位,宜强化自主技术研发、提升外资质量和技术外溢、加快"走出去"学习先进技术。     

外贸增长方式转变的环境效应实证研究——基于山东的数据分析

通过对山东省外贸出口、FDI与工业废水排放量关系的实证分析研究了外贸增长方式转变的环境效应,认为FDI对环境污染有抑制作用,但作用较小而且入世后较入世前作用降低;外贸出口加剧了环境污染,但入世后总体污染程度较入世前降低,最后提出相关政策建议。     

Trans-boundary Pollution and Brain Drain Migration

The economic effects of international brain drain migration in the presence of trans‐boundary pollution are analyzed. In autarky, both skilled and unskilled workers are expected to migrate from the less developed foreign country to the developed home country, if permitted. Surprisingly, under certain conditions, all workers, apart from skilled foreign ones, will gain (lose) from the migration of unskilled (skilled) foreign workers. Moreover, if skilled foreign workers are employed as unskilled domestic workers, then skilled foreign workers will gain but unskilled workers in both countries will lose. Whether or not skilled domestic workers will gain depends on the magnitude of the pollution spillover parameter. Brain drain migration persists under free trade if the demand for manufactured goods is strong.     

湖州市环境库兹涅茨曲线转折点分析

湖州市位于我国经济发达的太湖流域,近年经济发展迅速,同时又是我国的环保模范城市。分析该地区的经济增长与环境质量之间的关系,对于其他地区具有十分重要的借鉴意义。选择工业化学耗氧排放量、工业SO2排放量以及工业固体废弃物产生量表征环境污染的综合水平,以人均国内生产总值表征经济发展水平,对湖州市的环境库兹涅茨曲线进行分析,从工业污染物排放、三次产业结构变化以及环境保护政策和投资力度等方面分析。结果表明,1998～2008年湖州市环境库兹涅茨曲线大体呈现倒U型的变化特征,环境库兹涅茨曲线在2006年达到转折点,人均国内生产总值为29 088元,工业化学耗氧量、SO2、固体废弃物环境库兹涅茨曲线分别在1999年、2005年、2007年达到转折点,对应的人均国内生产总值分别是12 634.9元、25 030.0元、32 521.4元。     

外商直接投资对浙江省外贸结构的优化效应研究

本文通过分析商品进出口中的初级产品与工业制成品比重、一般贸易和加工贸易比重、产业内贸易指数、市场集中度指数和外贸企业主体结构的变化,来揭示外商直接投资与浙江省的外贸商品结构、外贸方式结构、外贸模式结构、外贸市场结构和外贸主体结构这5类外贸结构变化的关系,并以外贸商品结构为例,利用截面时间序列模型实证分析了外商直接投资对浙江省外贸结构的优化效应。研究表明：外商直接投资促进了浙江省外贸商品结构的优化,但对各产业的外贸结构优化效应存在显著差异,其中外商直接投资对机电产业的优化效应最为明显,其次是高新技术产业、服装产业和纺织产业,对第一产业的优化效应最小。     

Environmental regulation and trade pattern：a case of China

As a growing number of countries, including both developed and developing countries, have in recent yearstaken environmental regulation at different levels, a question of great concern has been raised： can the regulation alterthe existing trade volume and trade pattern, and ultimately drive pollution-intensive industries to countries with low-levelregulations or even those without regulations at all？ Starting from the three different propositions concerning therelationship between environmental regulation and trade pattern, this paper applies cointegration analysis and errorcorrection model to empirically testing the relationship between environmental regulation and trade in China during theperiod of 1985-2005. Our empirical results indicate that in the short run the collection of pollution discharge fees bearsa positive impact on the export share of clean products of total exports. Thus, higher pollution discharge fees raise theratio of clean products exports to total exports. This further indicates that more stringent environmental regulationpromotes the exports of clean products. In the long run pollution discharge fees are positively correlated with the exportshare of clean products but negatively associated with their import share. Such correlations imply that environmentalregulation tends to facilitate the international specialization in line with comparative advantages.     

中国对外贸易对环境污染影响的实证研究——全球视角下投入产出技术矩阵的环境赤字测算

文章以1993-2006年中国制造业的对外贸易和污染物数据为基础,结合投入产出表,测算了我国制造业对外贸易中的污染含量,借以考察对外贸易对我国环境污染的影响。研究结果表明:通过对外贸易我国正在为发达国家承担了高额的环境成本。     

Trade,Growth, and Environmental Quality*

This paper examines linkages between international trade, environmental degradation, and economic growth in a dynamic North–South trade game. Using a neoclassical production function subject to an endogenously improving technology, North produces manufactured goods by employing labor, capital, and a natural resource that it imports from South. South extracts the resource using raw labor, in the process generating local pollution. We study optimal regional policies in the presence of local pollution and technology spillovers from North to South under both non‐cooperative and cooperative modes of trade. Non‐cooperative trade is inefficient due to stock externalities. Cooperative trade policies are efficient and yet do not benefit North. Both regions gain from improved productivity in North and faster knowledge diffusion to South regardless of the trading regime.     

FDI对出口贸易结构影响的实证分析——以江苏省为例

本文利用江苏省1993-2011年的样本数据,实证分析了FDI与工业制成品出口额总体和内部结构两个层面之间的关系以探究FDI对出口贸易结构的影响。文章通过协整检验、Granger因果检验以及误差修正模型实证分析得出了：FDI促进了江苏工业制成品的出口额、内部的资本和技术密集型工业制成品出口额的增长,反映出FDI促进了江苏出口贸易结构的优化,即FDI是江苏出口贸易结构优化的一个重要影响因素。最后,文章提出了一些江苏合理利用外资以促进出口贸易结构优化的政策建议。     

The Question of Access to the Japanese Market*

It is now widely accepted that Japan has relatively low official barriers to merchandise, particularly manufactured goods, trade relative to other industrial countries. Yet, Japan's current account and trade surpluses have encouraged the view that there must be special ‘hidden barriers’ to accessing the Japanese market, and a literature has developed on the premise that Japanese business organizations (keiretsu) limit foreign penetration of markets of manufactured goods. This paper surveys the main elements of this literature and questions some of the assumptions upon which recent American policy in this area seems to have been developed.     

新疆经济增长中的能源消费与环境污染

本文的研究目的在于分析新疆经济增长与能源消费、环境污染之间的数量联系机制。文章首先对新疆经济增长过程中的能源消费与环境污染现状做了详细的描述性统计;然后基于1985年～2007年的时序数据,建立经济增长与能源消费、环境污染的协整方程。研究发现,新疆存在从能源到经济的单向格兰杰原因,为能源依赖型经济体系;新疆经济增长、能源消费、对外贸易构成环境污染的单向格兰杰原因;在影响新疆环境污染程度的各因素中,对外贸易对环境污染的影响是很大的。     

外商直接投资对中国环境污染影响的再考察——基于外资来源和行业差异视角

基于中国城市统计年鉴数据和中国工业企业数据库,采用GMM估计实证检验了外商直接投资(FDI)对于中国环境污染的影响效应。研究结果表明,FDI对于不同污染物的影响效应存在巨大差别,FDI提高了工业废水排放,降低了工业二氧化硫排放。进一步分析表明,造成这种现象的原因是港澳台投资和外国投资的质量和行业分布差异。港澳台投资具有负面的环境绩效,而外国投资对中国的环境污染状况具有改善作用。利用中国工业企业数据库,统计分析不同行业的外商资本金构成情况,发现不同来源的FDI在行业间的分布情况存在差异。FDI的质量和行业分布差异,导致FDI对不同污染物产生不同的环境效应。论文为学者们关于FDI对中国环境影响的争论提供了一个合理的解释,也对中国的引资政策和环境治理具有一定的参考价值。     

利用外国直接投资与贸易条件分析

通过大量数据说明。中国FDI主要流向劳动力密集型出口部门。这种流向特征一方面导致中国出口消费品的超额供给,另一方面又带动了对资本、技术等密集型产品的进口FDI需求的增长,使中国的贸易条件趋向恶化。要改善中国的贸易条件,应当进一步加强对外资流向的引导,从根本上增加外资流向资本技术密集型部门和服务业的比重,降低流向一般制造业的比重。     

Transboundary Pollution and International Migration

We analyze the welfare effects of international migration in the presence of transboundary pollution. We use a simplified Copeland and Taylor (1999) model, where the (developed) home country's pollution abatement technology is superior to that of the (less developed) foreign country. If there is no trade, workers will migrate from the foreign country to the home country. The foreign country gains from migration, but whether the home country gains or not depends on the abatement‐technology gap and the magnitude of the coefficient of transboundary pollution. World welfare will increase under migration. If there is free trade in goods, international migration occurs when the home country specializes in the production of the environmentally sensitive good. In this case, migration will result in increased production of the manufactured good and increase the level of world pollution.     

金融发展促进了对外贸易吗?——来自中国的证据

Using China’s panel data of 30 provinces during 1990–2003, this paper attempts to explore a possible link between financial development and China’s foreign trade. Four indicators are used to identify the role of financial development, which capture both the scale and efficiency feature of China’s regional financial development. The effects of other variables are also investigated, including traditional factor endowments, foreign direct investment, infrastructure and institutional quality, etc. In general, the estimation results suggest that financial development has a quantitatively large and robust effect on China’s manufactured goods trade, among which the financial efficiency indicators play a more significant role in promoting manufactured goods trade than those scale indicators. Sensitivity estimations show that the effect of financial development on China’s total trade essentially differs from that on trade in manufactured goods.     

我国对外贸易与环境协调发展的思考

从2008年开始,我国已成为世界第一大贸易强国。在对外贸易发展迅速的同时,环境污染十分严重。环境污染是经济快速增长的产物,而对外贸易则是我国经济增长的强劲动力。对外贸易发展对环境造成了不良影响,而环境问题又阻碍了对外贸易的进一步发展。因此,为了使我国的对外贸易与环境走向良性循环,必须协调好两者的关系。     

环境规制竞争对经济增长效率的影响:基于省级面板数据分析

利用1992-2008年中国31个省级面板数据,检验了环境规制竞争对生产率增长及其构成的影响。结果发现,SO2减排对生产率增长及其构成有正向影响,说明SO2的减排竞争将会促进经济增长效率的提高。相反,工业COD减排对生产率增长及其构成存在不利的作用。这种不利影响不是由省际间环境规制竞争引起,而是由废水治理策略不当造成的。这些研究结果似乎表明,环境规制竞争并非是发展地方经济的"良策"。     

The determinants of pollution levels: Firm-level evidence from Chinese manufacturing

Using a large, unique, firm-level dataset from the Chinese manufacturing sector, we study important factors that are related to emission intensity for three pollutants in China – sulfur dioxide, wastewater, and soot. Our main findings are as follows: (1) compared to state-owned enterprises (SOEs), both foreign-owned firms and domestic public-listed firms exhibit less intensive pollutant emissions; (2) firms in regions with less local protection have lower pollution intensity; (3) better property rights protection is negatively correlated with pollutant discharge over and beyond the national standards; and (4) larger firms, firms in industries that export more, and firms with more educated employees pollute less. These results suggest that China should not target foreign firms more harshly in its effort to reduce industrial pollution. Better institutions in the form of more effective law enforcement and lower entry barriers across regional markets are also means of curbing China’s pressing environmental problems during its current stage of economic development.
