The Relationship between Urbanization and Domestic Energy Consumption:An Empirical Study of Shandong Province,China

The rapid development of urbanization has led to a rapid increase in total energy consumption.The proportion of domestic energy consumption to total energy consumption has gradually increased and has become the major driving force for energy consumption.With the pressure from urbanization and domestic energy consumption,it is necessary to study the impact of urbanization on domestic energy consumption of the regional level and to explore the function paths of these two factors.The findings are helpful to realize sustainable development based on the actual situation analysis,horizontal survey data and statistical yearbook panel data.The current situation and changing trends in domestic energy consumption of Shandong Province are systematically examined through field investigation and survey questionnaire.The time-series econometric model is applied to analyze the relationship between urbanization rate and total domestic energy consumption.The research results show that the total domestic energy consumption and urbanization rate of Shandong are generally increasing.The urbanization rate development and domestic energy consumption have a long-term stable and balanced relationship.An increase in urbanization rate can cause an increase in domestic energy consumption.There is a slight difference between the average total energy consumption levels of urban and rural residents,but their energy consumption structures differ a lot.These findings provide basic data support and reference for local governments to formulate energy-conservation and emission-reduction policies.

The ASEAN experience of the purchasing power parity theory

We used panel data analysis to evaluate the relative purchasing power parity(PPP)hypothesis of the ten ASEAN member countries between 1973 and 2015.We incorporated the cross-sectionally augmented panel unit root test as proposed by Pesaran(J Appl Econ 22:265-312,2007).For panel cointegration analysis,we employed the four error-correction-based Westerlund(Oxf Bull Econ Stat 69:709-748,2007)panel cointegration tests.The Westerlund(Oxf Bull Econ Stat 69:709-748,2007)tests are general enough to permit a large degree of heterogeneity,both in the long-run cointegrating relationship and in the short-run dynamics,and dependence within as well as across the cross-sectional units.To check the robustness of the results,we further estimated the cointegration test excluding Indonesia and Brunei.The findings support our initial results.Further,all the results overwhelmingly support the relative PPP hypothesis.Consequently,the monetary authority would be able to implement a self-regulating monetary policy.It would also be able to control the exchange rates.

Research on the Relationship between Salary Incentives for R&D Personnel and R&D Investment in China’s Pharmaceutical Industry

Objective To explore the relationship between salary incentives for R&D personnel and R&D investment in China’s pharmaceutical industry through an empirical analysis so as to propose suggestions for increasing more R&D investment from the perspective of stimulating R&D personnel.Methods Based on the relevant data of the China’s pharmaceutical industry in the“China High-tech Industry Statistical Yearbook”and other data from the National Bureau of Statistics from 1995 to 2018,co-integration tests was used to construct error correction models and Granger causality tests to explore the relationship between R&D personnel salary incentives and R&D investment.Results and Conclusion There is a long-term balanced relationship between the salary level of R&D personnel in China’s pharmaceutical industry and the investment of R&D.For the per capita salary of R&D personnel increases by 1 unit,the internal expenditure of R&D investment will increase by 2.2451 units.In the short term,the per capita salary of R&D personnel has a slight negative impact on the internal expenditure of R&D investment.In addition,the salary incentives for R&D personnel have the most significant role in promoting R&D investment after five years of implementation.
