Tourism in the Canary Islands: forecasting using several seasonal time series models

This paper deals with the analysis of the number of tourists travelling to the Canary Islands by means of using different seasonal statistical models. Deterministic and stochastic seasonality is considered. For the latter case, we employ seasonal unit roots and seasonally fractionally integrated models. As a final approach, we also employ a model with possibly different orders of integration at zero and the seasonal frequencies. All these models are compared in terms of their forecasting ability in an out‐of‐sample experiment. The results in the paper show that a simple deterministic model with seasonal dummy variables and AR(1) disturbances produce better results than other approaches based on seasonal fractional and integer differentiation over short horizons. However, increasing the time horizon, the results cannot distinguish between the model based on seasonal dummies and another using fractional integration at zero and the seasonal frequencies.

城市基础设施投资结构的动态仿真与分析——以北京市为例

基础设施在城市化进程中扮演着关键作用,合理选择基础设施投资结构对于城市可持续发展至关重要。鉴于基础设施的多系统复合特征,结合系统动力学和耦合协调理论,构建了城市基础设施系统效益仿真模型,通过调整各类基础设施投资占比参数,设计出资金投入总额有限下的4种基础设施投资情景,模拟了北京市2018~2030年4种情景下基础设施效益子系统间耦合协调水平,提出了在模拟期内优化基础设施投资结构的参考方案。结果表明：2018~2030年4种情景下基础设施效益子系统间耦合协调水平存在差异,整体处于上升状态,由低度耦合协调演变为极度耦合协调;均衡兼顾型和现状延续型情景下的城市基础设施效益子系统间耦合协调水平分别在2018~2027年和2028~2030年两个时段内表现最优,更有利于推动城市可持续发展,可将此两种情景下的城市各类基础设施投资占比参数作为相应时段内城市基础设施投资的参考方案。     

The Theory and Evaluation Method of the Sustainable Development System About the Harmonious Growth of Population, Resource, Environment and Economy in the County District of China

The linchpin of strategy about the Sustainable Development (SD) in Chinese county enforcement area is to accomplish the basic transformation about the mode of economic development from extensive mode to intensive mode. For most counties of China, the overmany population is an element which influences the Sustainable Development. But to achieve the Sustainable Development based on the harmonious development of population, resource, economy and environment, the most important thing is how to carry on its management and evaluation method under the guide of the Tenth Five-Year Plan of national economy and the Perspective Target of 2010. Therefore ,this paper aims at reforming the traditional judging method focusing on output value-Income and establishing a systematic management method and evaluation index system about the sustainable development based on the harmonious growth of population,resource, economy and environment.     

Integrated System of Economy-Environment Accounting of China (CSEEA)─System Design and Trial Estimation (1992)

On the basis of the general framework of United Nations' indirect/satellite accounting system--Integrated System of Environment & Economy Accounting SEEA (1992) and 93' SNA, this paper tries to construct one simple, effective and practical CSEEA, and thereby trial estimates the 1992 Chinese environmental adjusted GDP (Green GDP), under Chinese National Accounting System's reform practice.
