近年来,随着中国社会经济的快速发展,中国居民的消费水平也发生了很大变化。消费是社会总需求中最重要的组成部分,是刺激经济增长的主要途径,因此研究消费对发展水平的影响具有重要的经济意义。根据2015年中国31个省的相关截面数据,本文通过国内消费支出和人均可支配收入的比例反映出的经济发展水平作为因变量,以食品支出、衣着、医疗保健、住房支出作为研究影响经济发展水平的实证因素,运用最小二乘法进行实证研究,同时通过多重共线性检验、自相关性检验等计量经济学检验方法对模型进行检验,得到各因素对于消费的影响方向及大小,得到相关结论。  相似文献

采用单位根检验、协整检验等计量经济学方法对2001—2011年黑龙江省13个地级城市面板数据进行实证研究,结果表明:现代服务业集聚与区域经济增长之间存在互为因果的负相关关系,即黑龙江省现代服务业集聚的专业化效应大于多样化效应,并对经济增长产生了抑制作用;政府过度干预尤其是直接投资能够加剧现代服务业集聚的专业化程度,继而加大现代服务业集聚对经济增长的抑制作用;同时,经济的增长要求区位熵下降,即要使现代服务业集聚能有效地促进经济增长,就必须实现代服务业集聚的多样化。  相似文献

Reliable short‐ to medium‐term prediction of the tender price index (TPI) is crucial to construction stakeholders, and this has stimulated the interest of the research community to seek a more analytical method for TPI forecast. The purpose of this study is to establish an econometric model for accurately predicting the tender price movements based on a group of associated financial and macroeconomic variables. Applying Johansen’s method for multivariate cointegration analysis, the tender price was found to be cointegrated with the gross domestic product, construction output and building cost. A vector error correction (VEC) model imposing the cointegration restriction was then developed for the purpose of forecasting. The model was verified against various diagnostic statistical criteria and compared with the Box‐Jenkins and regression models. With a mean absolute percentage error for a three‐year ahead forecast at 2.9% level, the developed VEC model outperforms the Box‐Jenkins and regression models, and is proven to be efficient and reliable in forecasting the short‐ to medium‐term tender price movements. The model can assist estimators to predict the TPI pattern in advance, and it can also help the public sector in planning for the construction workload to improve the stability of the construction market. Although the VEC model developed focuses on the Hong Kong construction market, the econometric technique can be applied to modelling other economic variables.  相似文献

In this paper, we investigate the role of input-output data sources in regional econometric input-output models. While there has been a great deal of experimentation focused on the accuracy of alternative methods for estimating regional inputoutput coefficients, little attention has been directed to the role of accuracy when the input-output system is nested within a broader accounting framework. The issues of accuracy were considered in two contexts, forecasting and impact analysis focusing on a model developed for the Chicago region. We experimented with three input-output data sources: observed regional data, national input-output, and randomly generated inputoutput coefficients. The effects of different sources of input-output data on regional econometric input-output models revealed that there are significant differences in results obtained in both forecast and impact analyses. The adjustment processes inherent in the econometric input-output system did not mask the differences imbedded in input-output tables derived from different data sources. Since applications of these types of models involve both impact and forecasting exercises, there should be strong motivation for basing the syste on the most accurate set of input-output accounts.  相似文献

Whether inter-regional migration equilibrates regional economic performance is a question which has received considerable attention in recent literature. The author examines that question, focusing upon regional unemployment rates and real wages within the context of a 24-hour equation econometric model of the interaction between regional wages, regional unemployment, and inter-regional migration in Australia. Used to solve for steady-state values of wage and unemployment differences, the model determined that the steady state involves non-zero unemployment rate differences and non-zero wage differences. The model is also used to investigate the stability of the equilibrating mechanism and to simulate the effects upon unemployment, migration, and wage rates of a shock to employment growth. The main findings are that inter-regional equilibrating forces are slow and do not help equalize regional unemployment rates or wages.  相似文献

Conclusions Because of the many theoretical and statistical problems inherent in the construction of regional econometric models, I believe that considerable caution should be exercised by anyone who tries to use one of these models. I intentionally chose to emphasize the negative aspect of these models because I believe there is widespread misuse of econometrics and I fear that many people do not realize how tenuous the conclusions drawn from econometric models really are. This does not mean that I recommend the abandonment of econometric techniques in regional analysis. Instead, I wish to emphasize the weaknesses of regression analysis which are usually not treated by model builders.Regional models may be useful in providing short term forecasts and in assessing the immediate effects of policy decisions. The national econometric models have had limited successes in this area, and it is possible that regional econometric models will also serve in this area.However, given the structural problems of econometric models and the dubious forecasting properties of national models when compared with simple projections of time trends, I remain skeptical as to whether regional econometric models are worth building for structural analyses or as long term forecasting aides. Probably, the best reasons for employing regional econometric models in these capacities are that these models yield information which may be better than nothing at all and that there still are no better techniques available.This research was sponsored by a grant from the Economic Development Administration (project number OER-224-G-68-12). The conclusions found in this paper are not necessarily those of the Economic Development Administration.  相似文献

We specify a system of equations that fully reflects the supply and demand sides of the market for agricultural open space at equilibrium. Although simple, the system is exceedingly flexible and allows for household and parcel heterogeneity. We derive an empirical model directly from the structural equations and contrast this using a simulated landscape with the econometric specification most often found in the literature. We then show how the model can be used to project land-use change into the future and for policy simulation. Finally, we use the model to examine the impact of common land conservation policies in Europe.  相似文献

A simple econometric model of a state personal income tax is presented. The model is designed for economies subject to rapid population increase by means of a double log specification of an average tax schedule. Various tests are presented to validate the model. It is then incorporated into a full econometric model and the revenue and general equilibrium effects of two types of tax cut are considered. It is found that changes in state personal income tax rate schedules and deduction provisions have significant general equilibrium effects on open economies and these result in substantial induced revenue impacts.  相似文献

This paper presents an econometric approach to analysis of the relationship between tourist expenditures and state tax revenues. Following earlier writers, a multiplicative tax production model is employed with number of tourists included as a proxy variable for tourist expenditures. Time-series and cross-section regressions are run for several tourist impacted categories of state tax. Data from Florida are used for the 1960–70 time period.The results indicate that the model performs well using ordinary least squares. Tourist elasticity estimates generated are used to compute hypothetical tax contributions. These appear to be reasonable, though no definitive statements about direct tax exportation can be made. The contribution of the paper is that it provides a beginning step toward econometric quantification of the tourist impact on state economies.The author wishes to thank Jon Silberman, Wayne Talley, and Tony Huggins for their help.

"An econometric model for forecasting net migration and natural increase is proposed and then estimated using time-series data for Texas. The model is simulated five years out-of-sample and found to be quite accurate in forecasting future population growth. It outperforms simpler prediction methods, thus indicating that explicit modeling of net migration and natural increase is superior to modeling only total population."  相似文献
