The impact of the post-1972 floating exchange-rate regime on US exports

By employing the techniques of cointegration and error-correction models, this article empirically investigates the impact of the post-1972 floating exchange-rate regime on the volume of US bilateral exports to Canada, Germany, Japan and the UK. The econometric models specified in the analysis were estimated using quarterly data for the sample period 1959:1–1997:4. The empirical results provide evidence that the post-1972 exchange-rate regime is less conducive to trade than the Bretton-Woods fixed exchange rate regime.

基于新疆经济增长的财政支出最优规模估算

财政支出规模反映了政府对经济的干预程度,然而财政在支出过程中有个量的把握,即占GDP的比重存在一个最优值。在最优值以内,财政部门为私人企业提供公共产品以及弥补外部性等,提高财政支出能够提高经济增长率,当财政支出超过这个最优值时,税收的扭曲作用会不断加强,增加财政支出对经济增长起阻碍作用。将财政支出纳入生产函数模型中,通过实证分析,估算出新疆的最优财政支出规模。     

人民币升值对两岸经贸关系影响的实证研究

本文利用1999年7月至2008年4月的月度数据,运用协整检验以及基于VECM的Granger因果检验等计量方法,封人民币升值封两岸经贸关系的影响进行探讨。结果表明,人民币汇率与两岸经贸关系的三个核心指标都存在长期稳定的均衡关系。从长期来看,两岸经贸关系的三个核心指标都是人民币名义汇率的单向Granger原因;而从短期来看,不存在Granger因果关系。至于人民币升值封大陆封台出口、大陆自台进口以及台商对大陆投资的影响,无论是长期还是短期,都不明显。简言之,人民币升值封两岸经贸发展的负面影响不明显,而且从长远来看,两岸经贸关系的发展将有利于人民币汇率的稳定。     

The transition of China's monetary policy regime: Before and after the four trillion RMB stimulus

This paper studies the monetary policy of China in a flexible time-varying parameter vector autoregression model with stochastic volatility, with a focus on the monetary policy regime change around 2009 when the four trillion RMB stimulus started. We find that China has been transiting from targeting money quantity to targeting interest rate since 2009. The interest rate policy instrument played a bigger role in the central bank's monetary policy toolbox. We check an alternative identification strategy and a couple of different model settings to show the robustness of this conclusion.

A model of deep ecotourism development and its empirical study

Ecotourism requires the harmony of all factors involved in tourism system for a multilateral benefit. Based on such cognition, a concept of deep ecotourism development is put forward which includes two connotations： on the one hand, it should give prominence to the display of the eco-culture of the tourist destination and tourists＇ eco-experience, in which way the development behavior on the tourist destination and the tourists＇ behavior will be regulated; on the other hand, it implies the deep harmony among tourist entrepreneurs and tourists, the local governments and the local residents, as well as tourist activities and the ecological environment in the tourism development for the multilateral benefit of every element involved and sustainable tourism development. The common sense is that the degrees in a certain tourism destination will differ and that consequently four levels of ecotourism are divided - very shallow ecotourism, shallow ecotourism, deep ecotourism and very deep ecotourism. To move shallow ecotourism toward deep one, two models of ＂four subjects and two wings＂ and ＂connecting the two wings＂ of deep ecotourism development system are introduced to make ecotourism industry favorable to the display of eco-culture and the sustainable development of the destination community. With the two models, a case study of ecotourism development in Louguantai National Forest Park was made as a demonstration. The ultimate purpose is to build an ideal new Shangri-La.     

服务型制造试点政策对企业服务绩效的影响

服务型制造是制造业转型升级高质量发展的重要方向。国家高度重视服务型制造试点工作,推动服务型制造创新发展。现有研究聚焦企业内部因素和外部市场因素对制造企业服务绩效的影响,对试点政策因素的促进作用缺乏关注。以浙江省经济和信息化厅分别于2017和2018年公布的第一、第二批服务型制造试点企业名单为基础,选取包含试点企业在内的浙江省200家具有服务特征的上市制造企业2013-2019年面板数据,通过双重差分分析,检验服务型制造试点政策对企业服务绩效存在的影响。研究发现,服务型制造试点政策的实施对制造企业服务绩效的提升具有显著正向的影响,并且理论上试点带来的企业声誉可能会进一步增强这种提升作用。此外,试点政策对服务绩效的影响存在异质性特征,其净影响随着试点政策的持续而不断加强。具体表现为从试点第一年到试点第三年,企业服务绩效提升速度逐年提高。研究结论有效验证了浙江省服务型制造试点政策实施效果,为我国服务型制造试点政策的制定、实施与改进提供了启示。     

A novel time-series model based on empirical mode decomposition for forecasting TAIEX

Stock price prediction is regarded as a challenging task of the financial time series prediction process. Time series models have successfully solved prediction problems in many domains, including the stock market. Unfortunately, there are two major drawbacks in stock market by time-series model: (1) some models cannot be applied to the datasets that do not follow the statistical assumptions; and (2) most time-series models which use stock data with many noises involutedly (caused by changes in market conditions and environments) would reduce the forecasting performance. For solving the above problems and promoting the forecasting performance of time-series models, this paper proposes a hybrid time-series support vector regression (SVR) model based on empirical mode decomposition (EMD) to forecast stock price for Taiwan stock exchange capitalization weighted stock index (TAIEX). In order to evaluate the forecasting performances, the proposed model is compared with autoregressive (AR) model and SVR model. The experimental results show that the proposed model is superior to the listing models in terms of root mean squared error (RMSE). And the more fluctuation year (2000–2001) occurs, the better accuracy of proposed model will be obtained.

An empirical study of firm productivity growth based on the dynamic selection model: Effects on the recent decline in Korean exports

Export and productivity growth in the Korean manufacturing sector have both been slow since 2011. To understand this relationship, we examine the productivity distributions of manufacturing firms in Korea by applying the dynamic selection model developed by Sampson (2016). The fitness of the dynamic selection model suggests that a slowdown in the market selection mechanism may be a crucial contributor to the stagnant growth in the productivity. In addition, we find that the productivity difference between exporting firms and non-exporting firms has decreased and the low productivity growth of firms exporting to non-foreign affiliates has contributed to this trend.     

Technological progress and market growth: An empirical study based on the quality-ladder approach

This paper develops an extended version of the quality-adder model by allowing for heterogeneous markets. Based on this model, it presents an empirical analysis of innovation-based growth at the market level using a technometric measurement concept. It can be shown that a growth-promoting effect due to technological progress in a particular single year is observed after between 2 and up to 7 years. This is true not only for highly innovative markets but also for those in which fewer R&D resources are invested.

The mapping arrays details on the evolution of the technology under study and contributes to understanding the macro-technology development status. We generate a global technology roadmap for electric vehicles to demonstrate the approach in an empirical study.     

An empirical analysis of night-time light data based on the gravity model

This article aims to explore the feasibility of applying night-time light data to the study of trade. Based on 61 countries’ panel data from 1995 to 2012, this research used night-time light data, as the substitute for GDP, to study trade development based on the traditional gravity model. The method of ordinary least squares, Poisson pseudo-maximum-likelihood and two-stage least squares were used. The results show that geographical distance, country borders and regional agreements have a significant effect on China’s trade with other Belt and Road countries, which verifies the validity of trade research based on night-time light data analysis. Additionally, comparisons reveal the trade trends predicted by night-time light data from 1996 to 2012, were highly consistent with the actual data. This article stands as the first study to apply night-time light data to the gravity model in the research on trade between China and other Belt and Road countries. Breaking new ground, this research uses night-time light data as an economic indicator to study trade, in combination with micro foundations and the latest findings of the gravity model. Thus, this article deepens the understanding of trade analysis and contributing to the field of related researches.     

The choice of exchange rate regime: An empirical analysis for transition economies*

We analyze the choice of exchange rate regimes of the 25 transition economies in Europe and the CIS after 1990. The empirical results show that the traditional Optimum Currency Area considerations provide relevant guidance for the regime choices in these countries. Moreover, regime choices are influenced by inflation rates, cumulative inflation differentials, and international reserves sufficiency. That is, macroeconomic stabilization and the ability to commit to exchange rate pegs also play important roles. Large government deficits have ambiguous effects; they increase the likelihood of moving from flexible to intermediate regimes as well as that of moving from fixed to intermediate ones.
