Public Private Partnership (PPP) mode is increasingly applied in civil air defense (CAD) projects to improve project quality and reduce the government's financial pressure. Because CAD project has different attributes during wartime and peacetime states, it's necessary to comprehensively consider the project performance under different states to conduct scientific performance measurement. This paper focuses on the process of construction, operation, and handover of CAD PPP project to construct a unified project performance measurement indicator system, then a system dynamics (SD) model is established to carry out dynamic performance measurement and simulation of CAD PPP project under different social states respectively. A case study is conducted to verify the effectiveness of the proposed SD model, model validation, sensitivity analysis and result analysis were included as well. The study result can make the project performance management of CAD PPP more scientific and reasonable, and help decision-makers to formulate effective performance improvement strategies. It's found out that government plays an important role in CAD PPP projects, when resources are limited, the government should give priority to measures such as reducing tax rates and increasing subsidies to ensure project benefits. The research methods can also provide reference for performance measurement of other PPP projects.

Construction industrialization (CI) has been adopted worldwide because of its potential benefits. However, current research shows the incentives for adopting CI may differ in different regions. While the promotion of CI in China is still at the initial stage, a systematical analysis of the driving factors would help decision makers get a comprehensive understanding of CI development and select proper strategies to promote CI. This research combines qualitative and quantitative methods to explore the construction industrialization driving factors (CIDFs) in China. The grounded theory method (GTM) was employed to explore CI concepts among 182 CI-related articles published in 10 top-tier journals from 2000 to 2017. A total of 15 CIDFs were identified, including one suggested by professionals during a pre-test questionnaire survey. The analysis showed that the development of CI in China is pushed by macrodevelopment and pulled by the government and is also a self-driven process. The major driving factors for CI adoption in China are the transformation and upgrade of the conventional construction industry and the solution of development dilemmas. Our study also suggests that pilot programs are, currently, the most effective method to promote CI in China and to accumulate experience so to gain recognition by the society. This research is also of value for CI promotion in other developing countries.

Aiming to balance the interests of the principal stakeholders (the private sector, the government and the general public) in Public–Private Partnerships (PPP) projects, the satisfaction of stakeholders were researched thoroughly in this paper. A satisfaction evaluation model was structured based on authors' prior questionnaire survey focusing on the performance objective indicators (POIs) of different stakeholders. The parties' preferred POIs were identified as follows: all three parties emphasize the objectives of construction quality, service quality, cost, time, and lifecycle cost very much. Individually, the private sector prefer the objectives of profit making and government support, the government prefer the objectives of budget saving and risk transfer, and the general public prefer the objectives of toll rate and the facilities' quantities. Furthermore, a satisfaction adjustment model was proposed based on the interrelationships of the adjusting POIs and their impact on the stakeholders' satisfaction by using the feedback loops of System Dynamics (SD). An illustrative case was also introduced, the results of which indicated that the satisfaction evaluation and adjustment model could be well applied to balance the interests of stakeholders and also improve the general performance of the project.

In recent years, China needs far more financing for transportation infrastructure than can be provided by the government alone. Meanwhile the capacity of the Chinese government to provide public services on its own in an effective and efficient way is being questioned and reassessed at various levels. Accordingly, the involvement of private investors in the development of Metropolitan Transportation Systems (MTS) has been promoted by the Chinese public sector by means of adopting the Public Private Partnership (PPP) model. However, China's dynamic and complex political, financial, legal and regulatory environment makes the private sector adjust to accommodate the existing regime by way of understanding the driving factors in PPP applications for improving the chances of project success. This paper presents two case studies in China's MTS. Based on a case study and comprehensive literature review, 15 driving factors associated with PPP projects from the perspective of the Chinese public sector have been identified. A structured questionnaire survey targeting the public sector has been conducted to seek, analyze and integrate its perception of the driving factors. Through statistical analysis of the relative significance of each of these driving factors, the writers determined five common major dimensions of the Chinese public sector's purpose in developing PPP schemes, and the key factors that quantify each purpose. The establishment of the measures for these objectives and the key factors that quantify each of these purposes will likely be useful in encouraging private participation in infrastructure management and directing/concentrating efforts of the private sector to deliver quality public services under mutually beneficial long‐term contractual arrangements. Santrauka Pastaruoju metu Kinijai reikia daug daugiau finansavimo transporto infrastruktūrai pletoti, nei gali suteikti vien šalies vyriausybe. Jos galimybes veiksmingai ir efektyviai teikti viešasias paslaugas tiriamos bei vertinamos ivairiais lygiais. Skatinamas privačiu investuotoju itraukimas i metropolijos transporto sistemu (MTS) pletra, taikant viešojo ir privataus bendradarbiavimo modeli. Tačiau Kinijos dinamiška ir kompleksine politine, finansine bei teisine aplinka priverčia privatu sektoriu derintis prie egzistuojančios tvarkos, atsižvelgiant i pagrindinius viešojo ir privataus bendradarbiavimo veiksnius, kurie padidintu projekto sekmes tikimybe. Straipsnyje pateikiami du Kinijos metropolijos transporto sistemu pletros pavyzdžiai. Remiantis nagrinejamais pavyzdžiais ir išsamia literatūros analize, iš Kinijos viešojo sektoriaus poziciju identifikuota 15 pagrindiniu veiksniu, susijusiu su viešojo ir privataus bendradarbiavimo projektais. Buvo atlikta apklausa, orientuota i viešaji sektoriu, išanalizuota, kaip pagrindiniai veiksniai suvokiami ir pritaikomi. Atliekant kiekvieno iš šiu veiksniu santykiniu reikšmingumu statistine analize, buvo apibrežti penki pagrindiniai Kinijos viešojo sektoriaus tikslu aspektai, pletojant viešojo ir privataus bendradarbiavimo schemas, ir pagrindiniai rodikliai, ivertinantys šiuos tikslus skaitine išraiška. Minetu tikslu nustatymas ir pagrindiniu skaitiniu rodikliu ivertinimas galetu būti naudingi, skatinant privatu sektoriu prisideti prie infrastruktūros valdymo, galetu padeti koncentruoti bei nukreipti privataus sektoriaus jegas kokybiškoms viešojo sektoriaus paslaugoms teikti, remiantis abipusiškai naudingomis ilgalaikemis sutartimis.
